Editor's Okna Window Review

Okna vinyl windows sit at the very top of the rather large vinyl window industry as a whole, along with Soft-Lite, Sunrise, Kensington, Polaris, and Vytex. (But remember that many companies make 3 different levels of window—their economy, mid range and premium series.) The fact that Okna is often mentioned in this very top tier is impressive given that fact that there are literally hundreds of vinyl window manufacturers in the United States. Okna offers some nice wood veneer interior options that consumers would do well to take a look at - the look of wood without the maintenance and cost! (Click to explore Sunrise window reviews.)

The company manufactures 6 different window models that have both names and numbers attached to them. There is the 400 Series or Precision Weld, 500 Series or Insul-Tec, 600 Series or Eco Pro, 700 Series (Casements and Awnings), 800 Series or Envirostar, and finally the 900 Series or Starmark. Note that the 900 Starmark is a composite window, not a vinyl window frame like the other 4 series.

The company offers two basic packages, their Standard and Deluxe. The Deluxe is an upgraded glass and performance package that will improve the energy efficiency of the windows - expect to add $50 per window for this upgrade.

The only real downside to Okna is availability - they are Pennsylvania based and have good distribution in neighboring states and the region in general, however they are not available in the west. We hope they do expand, because they are one of our top picks for consumers.

Okna Vinyl Windows

The 400 Precision Weld is their economy or entry level window that is okay. It's not a bad window (a good one for an entry level window), but it isn't going to offer the same energy efficiency numbers or durability as the 500, 700 or 800 models. The step up is the 500 Insul-Tec and here is where you are getting a very good vinyl window. It might lack a few of the bells and whistles of the 800, but it is an excellent window and probably the best consumer value in the Okna fleet.

The 500 model is going to be on the thinner side compared with other vinyl windows, which consumers are going to like (more viewing area, less frame.) Other window companies often market a thinner frame, but these come with worse performance, while the 500 maintains some nice energy efficiency marks. (If someone asked me, what is the best window for the price, I would have to mention the 500 Series with the Deluxe glass package) The 700 series is their casement and awnings and they are comparable in quality and cost to the 500 Series.

The 800 EnviroStar is the premium vinyl window from Okna and one of the best vinyl windows available. An excellent window, but it is pricey and some consumers balk at paying such a premium price for a vinyl window. (It is worth noting that well made vinyl windows will blow the doors off of wood windows in terms of energy efficiency - organic materials can never match inorganic in this regard.)

Okna Composite Windows

The 900 Starmark window is a composite window that also sits at the very top of the composite windows on the market. The 900 is quite bulky, but if you can get past the depth and bulk, it is a fantastic performing window that is sturdy and strong. The Starmark is going to be thicker from the edge of the glass to the edge of the frame compared to their 500 or 800 model.

Okna Windows Warranty

The Okna window warranty is one of the strongest in the business. It covers the windows for the life of the owner and is completely transferable to another homeowner. It's a single page warranty that you can actually read, instead of the some 3 page tiny print warranty that looks like its written by a team of lawyers and full of confusing language.

Okna 400 Windows Reviews

The Okna 400 window is one of the best low priced models on the market. With the Deluxe package, you get a U-value of 0.28, AI of 0.05, and SHGC of 0.30. You can see advertised deals of around $400 but to get the best install, expect to pay around $450, which is still a good price. It doesn't have some of the fancy options and upgrades that more expensive windows offer, but it is an excellent budget window.

Okna 400 Window Bid

Hi Dane, I got a quote from Okna dealer. $11200 for 1 slider door, 1 bow (5 windows) and 11 slider windows. These are all foam filled and triple pane. Among these 11 original Windows, 1 is single casement. rest are all 2 casement with a picture window in the middle. Some are pretty wide. thus he suggest to use slider since double hung will looks strange on some of the wide windows. it is a old brick house with metal frame around it. My house is close to a train station. He also said laminated option will be $250 more per window.

Wonder if this is a fair price? I live in long island not sure if local price is higher than national average.

Thanks so much

Ming - Homeowner - from 2018

[Site Editor's Answer]

I'm going to assume the slider is $2K and the bow is $2.5K, which makes the breakdown for the 11 windows $558. That's a very good price for an Okna 400 window—for the triple pane and foam fill, that's a great price!

In terms of noise reduction, I'm not sure that a laminated glass for $250 per window makes a lot of sense. The biggest factor in noise reduction is the amount of space between the panes of glass. I would think that the triple pane would go a long way towards this. You may want to ask the Okna dealer about different glass thickness between the panes. Using panes of glass that have different thicknesses will reduce different sound frequencies. Also ask if the company sells an NRG or noise reducing glass that isn't a laminated, but will help with the sound.

To be honest, a good Okna window is probably all you need for noise reduction (from a sensible cost perspective). You should probably think about air-sealing your walls, this can make a huge difference. I would get a few estimates on this and get their opinions on how to best reduce the noise.

Okna 400 vs. Simonton ProFinish

I need 10 slider windows and 5 sliding patio doors. I have narrowed down my bids to two: Sunrise standard windows and Simonton ProFinish Doors. The other option is the Okna 400 series and SoftLite Doors This process has been mind boggling and I'm spinning at the quotes and different options.

Nan - Homeowner - from 2018

[Site Editor's Answer]

Nan, I like both these options to tell you the truth. I think I would do the Okna route with the Soft-Lite doors. I like Sunrise windows, but the Soft-Lite door is better in my opinion over the Simonton ProFinish door.

Tim - Site Editor - from 2018

Okna 400 vs. Simonton 6100

Recently bought a townhouse that needs to facelift, especially the windows. Home Depot gave us a quote on the Simonton 6100 window. For 12 windows it would be $7,500. I live in New Jersey and was wondering if you have any suggestions on this bid, or any others.


Karen - Homeowner - from 2017

[Site Editor's Answer]

Karen, the Simonton 6100 is decent, but the bid is pretty high at $625 per window.

Since you are in New Jersey, you should be able to access a bid on Okna windows, which are a full step up from what you have. Also Ideal makes a good premium window in the Majestic series that might be about that same price. However, you would be getting a MUCH better window.

Okna 400 Series In Wisconsin

Dan - I'm interested in pocket replacement windows for 7 of my home's slider windows and the Okna 400 series appeal to me as a good choice. However, how do I locate a dealer in my area of FondduLac, Wisconsin or nearby area who would come to my home for a quote. Any assistance in this matter would be appreciated.

Dick. - Homeowner - from 2017

[Site Editor's Answer]

Dick, this company looks like it sells Okna windows. I know nothing about them but certainly call them up and get a quote, then make sure they have good reviews!

Okna 400 Window Review

I got quotes from a dealer for both the 400 Precision Weld and the Gorell 5100. I need 4 sliders, 3 of them large ones, and 6 double hung windows. The Oknas would be $5750. The Gorells are $5950. The dealer said the Oknas are better, but the price difference is mainly because their sliders are less expensive. My question is, if price is ignored, which is better in quality? Are the prices reasonable, or should I look at something else?

Mary - Homeowner - from 2011

[Contractor Response]

Gorell is a good window, but Oknas are better. They're just a higher class window. The pricing for the Oknas is great, you'll have decent energy efficiency too. If you're install is good, then you won't really do any better than these.

Holland - Contractor - from 2011

[2nd Response]

Okna... although the Gorell is also good. The only thing I'd recommend is looking at the Okna 500s. They're a little more expensive, but not much, and they are a better product. I work with both of these windows, and I have to say the Okna is better all around. There's nothing wrong with Gorell, they just aren't at the same level as the Oknas. That price quote for either one is really good.

Okna 400 vs 500 Series

Hi Dane, I am looking to install the OKNA windows and have requested the installer in my area about the 500 series. He told me the 500 is not used for replacement windows but for new construction. Yet I see from a number of reviews this is not so. They only carry the 400 and can obtain the 800 but they informed me there is minimal difference.

From what I read I feel like u am not being provided full disclosure. How do I find an installer who carries the 500 series. I live in Easton PA.

Kind regards,

Ann - Homeowner - from 2015

[Site Editor's Response]

Ann, the 500 Series or Insul Tec is listed right on their website under replacement windows so unless something has changed with their line up that I am unaware of, I don't what he's talking about. Yes, something seems a bit off about the person you are working with.

I tried to contact Okna, but I couldn't get an actual person on the phone to see if anything has changed. I would suggest filling in your information on their website and see what they come back with in terms of installers in your area. I would also suggest getting a couple of additional bids, Sunrise and Soft-Lite should be in your area.

Okna 500 Windows Reviews

The Okna 500 window (also known as the Insul-tec) is used as a replacement window, but sometimes is seen in new construction as well, with a nailing fin or a flange and J-channel. The efficiency numbers are a little better than the 400, with a U-value of 0.25, AI 0.02, SHGC 0.28, and DP50.

In addition, it has some upgraded features. The sill wall is improved and it comes with a Duralite spacer. The 500 series is an excellent vinyl window that is certainly a window I would have in my own home.

The Okna 500 series differs from the upgraded Okna 800 series in the following ways. The 500 gets a .02 AI (the 800 gets a .01), the 500 does not have a magnetic seal along the bottom of its lower sash (the 800 does), the 500 uses a vinyl lift rail (the 800 uses a metal lift rail), the 500 does not allow consumers to upgrade to a brass or nickel harware (the 800 does), and finally the 500 offers only internal grids (the 800 offers SDL).

OKNA Insul-Tec Complaint

Good day. I came across your site on Okna reviews and found your information quite useful.

We live in Maryland and had our windows replaced in 2015 with OKNA Insul-Tec replacement windows. 27 windows in all which cost $18, 425 (with discounts). The original quote was $22,746. Here is a breakout of the windows installed:

I was told these are some of the best performing windows for the price. However, I am no longer convinced. We had two windows develop cracks on the inside pane (the half moon and one 24x62 DH w/o grids). Also we just noticed one 32x64 DH w/grids has several areas that are fogged up. I thought the outside glass was dirty but it is not. The issue is between the glass panes. When it is windy out I can feel the cold air come thru where the window sashes meet.

Have you come across issues like these regarding these windows?

I’m also baffled on how I could be using more energy than my neighbors:

Jesse - Homeowner - from 2019

[Site Editor's Answer]

Jesse, normally Okna makes a very good window. I would definitely call the local rep and have them come out and look at the windows, which should be under warranty. They should not be fogging up inside the window panes. As a company Okna is alos good, on par, at taking care of their warranty issues.

Every company has some issues and I have heard of Okna windows having problems, but not many. Not as many as most other companies. I would definitely try to get some relief from them first.

Dane - Site Editor - from 2019

[Jesse's Reply]

Thanks for the reply, Dane. I spoke with the rep and he mentioned that the fogging issue I had was probably due to the drastic changes in temperature and the fact that the windows are filled with argon, however only about 95+% since it’s impossible to fill them up 100%. He did state that if it didn’t go away to let them know and they would have it replaced for free since it is warranted.

Jesse - Homeowner - from 2019

Okna 500 series or Harvey Classic

Hi, I live in Massachusetts and am debating between the Okna 500 series and the Harvey Classic. I know you like the window, but I didn't like the bid from the Okna guy. I have 16 windows, all of which are sliders, except for two of them, which are XOX. The bid from the Okna guy was 12600, while the Harvey guy was $11,275 with a 20 year warranty on the installation/labor.

Which bid is more reasonable?

Marty - Homeowner - from 2018

[Site Editor's Answer]

Marty, it's a sham about the Okna rep and your experience. For the money, the Okna bid is probably better, but I would not advise you to go with someone who gave you a bad feeling when they came out. I might give them one more shot to give you a bid though just to see if your first impression was correct.

The Harvey bid is not bad and they make a solid vinyl window. If you can't change your opinion on the Okna, then the Harvey bid is the place I'd go next.

America’s Windows Basement Windows

Hi. I am in Cincinnati. I was quoted over $6000, down to $5000 and a final price of $4500 for six hooper basement windows, (two need to be vented, so, a composite vs. glass to be used). My windows are steel encased which I was told encasement has to be removed (adding to the cost, but included). The company is America’s Windows. I was told they use Okna windows, I think the 500.

I’ve received quotes from companies $1800 (for three windows) to over $7500 for these windows, all claiming to use quality windows. Two other makers were Alside and Improveit, LLC (Improvit said they make their own windows?) Is the America’s Windows a fair quote ?

Another question, are there windows other then glass block that can keep the glass and be vented ?

BT - Homeowner - from 2018

[Site Editor's Answer]

BT, I can't quite tell you if that's a fair quote only because this sounds like a pretty specific project. However, if the lowest quote you have is $1800 for 3 windows, then I'll assume the total quote for that bid would be $3600. So going with an Okna 500 window (one of the very best windows around) for an extra $800 sounds like a decent deal to me.

I'm not familiar with America's Windows. I would call up Okna headquarters and ask them to vouch for the company. Not sure how that will play out but it may bear fruit. I quickly looked them up online under the google search "america's windows reviews" and saw that the yelp reviews on them were pretty impressive. Also, Okna is a well respected company so their dealers tend to be pretty good as well -- I'm not saying they are in every case, I'm simply pointing out an industry rule of thumb.

If you aren't satisfied with this bid and the others you have so far, keep getting more until you have your answer. That's the one nice part of this process, its free. It's just a pain in the arse. :)

Okna 500 Quote vs. Ideal Duraweld

We have been looking at quotes to replace our vinyl windows in our 1920s home. There are 22 windows and 1 inside and 3 outside storm doors. The quotes have been all over the place. The most recent uses Okna 500 series windows and Larson and ProVia for the doors. The doors are custom sizes, but I believe the windows can use standard sizes, even for the basement. This quote came in at $17,470.

We also have a quote for 22 Ideal Duraweld windows, and doesn’t include the cost of any doors. That was $12,800.

I believe the Okna windows are a better choice, but I don’t have a good idea of what the doors should cost. Should I expect the doors to be $4,500+ for 4 doors?

Thanks for your expertise and input!

Kelley - Homeowner - from 2018

[Site Editor's Answer]

Kelley, the Okna quote looks quite solid, lower I would estimate than the Ideal quote. I would say the doors would be $1500 at least, so $6000 for 4 doors. I'm totally speculating here.

The Okna dealer who gave you the bid should be able to break down that bid for you to show you what the windows cost and what the doors cost. It's also worth noting that Larsen and ProVia make very good doors.

The Ideal Duraweld is quite a good vinyl window, but I'd still put the Okna 500 above it. Assuming I felt like the installer was going to do a good job, I would pursue the Okna bid myself.

Okna 500 Double Hung Deluxe Quote

Hello, I was quoted $11,088 for 13 Okna 500 double hung deluxe 35.75X53.5 , 2 Okna 500 double hung deluxe 35.75X37.5, 2 of the same model with dimensions 23.75X53.5, and 1 picture window insul-tec 510 deluxe 47.75X53.5.

The price includes all installation, labor, and materials. This is for the NC area. Would you be able to tell me if this is a fair price? I feel as if it's a bit high. I can provide more info as needed. Thank you for the help!

Catline - Homeowner - from 2016

[Site Editor's Answer]

Catline, at frist glance that feels quite high. Is the cost of the installation high? Can you get a bid breakdown of materials and cost?

So you definitely need additional bids to see whether the bid is high or fair. I'm thinking that it's at the top price range of the bids you might get. Now the Okna 500 is a fantastic window, so that's good you got the bid.

I would contact a dealer from Sunrise, Soft-Lite, Zen, Vytex, Polaris, Kensington and possibly Wincore and Simonton. Not all of these of course, but I wanted to give you more options than you might need.

The other reason to get some more comeptitve leads is to use them as a bargaining chip to possibly lower the Okna bid, assuming that's the one you eventually want to go with.

Okna 500 vs Paradigm 8300

I am in the beginning stage of getting information & quotes on replacing 15 windows in my house. I just had a price quote for the Paradigm 8300 ($600 to $650 installed). I also just spoke to a neighbor who has Okna windows and was wondering how the Paradigm 8300 compares to the Okna 500 or other Okna windows. Thanks Brian

- Homeowner - from 2018

[Site Editor's Answer]

Brian, while the Paradigm 8300 is a very solid vinyl window, the Okna 500 is better in my opinion. If for no other reason, than the Paradigm 8300 uses a pocket sill, which is a poor sill design that funnels water through the frame and out weep holes that can clog over time with gunk and mold. The Okna 500 is one of my favorite vinyl windows out there and the winner in this head to head match up. I would think the Okna would be in the ballpark price of the Paradigm quote.

Okna 500 Delux vs. Wincore 7700 Series

Hi, I have a 1992 built house with original wood windows, 22 in total. I am looking to replace them all and I saw your advice on replacement windows and I am having a contractor come to me on Thursday to give me a quote.

Meanwhile I have 2 quotes one from home depot and other from another local contractor that is planning to install Wincore 7700. The quote is around $16,500 with a patio door installed with aluminum moulding outside and with windows with grills inside.

I was hoping for it to be around 12K-13K for best windows I can get like Okna 500 Delux, is that in the right range or is there some other advice you can give?

I live in Wisconsin.

Thanks in advance for your help.

K - Homeowner - from 2018

[Site Editor's Answer]

K, for simplicity sake, I'll assume that the patio door quote is $2K. That breaks down your per window cost to $650. That doesn't strike me as out of the ballpark of what I'd expect for the Wincore 7700 series. It would feel excessive for the lower end Wincore 5400 series windows. The overall bid is perhaps a bit high but that could simply be accounted for based on the size of your windows. Most contractors bid out their windows by the lineal foot, which isn't practical for our cost calculator because its way too complicated and time consuming.

The key to getting the best prices is simply to get a ton of bids. Not only will it give you a better sense of what an appropriate price is for your particular project, it will possibly draw out lower bids from companies who may need the work more. You can also use the bids you get as leverage to find the companies lowest price (which often isn't their initial bid). Also, bids can be all over the boards.

You are correct that the Okna 500 often comes in at the $550 to $650 price range -- get your next bid and see where it is. If you don't like it, get a couple more bids. The process can feel like a lot of work, but it's worth it in the end.

Okna Insul-tec Window Bid

Hello Dane, got a quote for Okna Insul-tec window from one of the local window installation company. Any comments you may have is appreciated in terms of type of windows and overall if the estimate is fair. The sunseal glass package on some of the window is for the rear of the house which gets quite of bit sun throughout the day in Altanta area.

I am replacing builder installed original wooden windows. The installation will include replacement all Rotten Wood Sills & Trim and Cover with PVC coated Aluminum Trim Coil. Overall is installation considered standard installation? I tried to price it online but it gave me a quite low number, as such the email.

The windows have a u-factor of .25, shgc of .30 and an air leakage of .02.

Here is what the quote came in at -- 28 windows, several of them pretty big - $16,900 but with a cash discount I would pay $15,522.

Arpan - Homeowner - from 2018

[Site Editor's Answer]

Arpan, that's a good price for the Insulation-Tec, replacing woods sills/trim and aluminum wrapping. Very good in fact (comes out to $603 on the non-cash price). Great window, great price. If the installer has a solid reputation (many Okna dealers do), then I'd say you are one lucky guy. Now knock on some wood and move forward on your project!

Dane - Site Editor - from 2018

Okna 500 vs. 800

I just got a bid from Okna windows on 11 windows total. 8 of them are 36 inches by 58 inches and 3 are 20 inches by 38 inches. The bid came in at $580 per window and that included foam in the frame, some sort of added upgraded. I could also use their better 800 series but that would be $800 per window.

Which is the better option?

Chuck - Homeowner - from 2018

[Site Editor's Answer]

Chuck, the Okna 800 window is one of the best out there, but it isn't worth $220 more than the 500 series. The Okna 500 is a very good vinyl window and $580 per window is a very fair price. This would be the option that I would go with.

Okna 500 Double Pane Glass

Hi Tim, I think I’m going with the Okna 500 double pane glass. Louisville only has one dealer in the area that sell the Okna window. America’s windows. I was wondering if you have heard of any complaints about dealers selling a model to a customer but the customer actually gets the next lower product or window model?

Michael - Homeowner - from 2018

[Site Editor's Answer]

I have never heard of a company doing that, but it doesn't mean it can't happen. If the company is reputable, they won't do that. Just double check with the installers when they deliver the window.

The Okna 500 is a fantastic window, good luck to you.

Tim - Site Editor - from 2018

Okna 500 Deluxe vs. Polaris UniShield Plus

I am looking at 2 replacement windows by Universal Windows Direct but different contractors. One is Okna 500 deluxe (energy saving package). The other is Polaris ( UniShield Plus). In your opinion, which are the better windows? The warranties are the same. Thank you for help.

Robert - Homeowner - from 2018

[Site Editor's Answer]

Robert, I would go with the Okna 500 DX over the Polaris Unishield Plus. Universal relabels the Polaris window and sells the Unishield Classic, which is the Polaris ValuSmart window and the UniShield Plus, which is their ThermalWeld. The ThermalWeld is a nice window, but the Okna 500 DX is the much better of the two.

Dane - Site Editor - from 2018

Okna 500 vs. Provia Endure

I’m down to the provia endure double pane and Okna 500 double pain. Have you heard of many complaints with painted vinyl? I’m favoring the provia that will be painted, does the paint hold up?

Michael - Homeowner - from 2018

[Site Editor's Answer]

Michael, I actually don't know what process ProVia uses to paint their vinyl. Most companies will offer a warranty on the a vinyl window that isn't white, i.e. uses an exterior or interior colored.

There are a number of ways to add a color to vinyl -- painting, profile wrapping or laminates, and a co-extrusion process. There isn't one method that is more popular than another.

The ProVia Endure is a very good window.

Okna 500 Deluxe vs. Harvey Classic Window

Good Morning Tim – I have been using your site for the last week, comparing different vinyl window reviews. My question is: We are replacing 17 double hung windows and 2 picture windows. We are down to 2 names: Harvey Classic Window and Okna 500 deluxe. They are both with different contractors and comparable in price.

Please advise on which one you think would be the better option. (we are replacing the original windows with storms on them in our 1968 ranch)

Any help/advice you can give, would be great.

Thank you.

Vicki - Homeowner - from 2018

[Site Editor's Answer]

Hi Vicki, thanks for using the site. Both Harvey and Okna are quite reputable companies. While I find the Harvey Classic to be quite a good window, the Okna 500 Deluxe is an excellent window. Either that or the 800 model is what I'd have in my house if Okna was actually available where I live. Obviously, you want to make sure that the installer is reputable and know what they're doing, but assuming this is true, the Okna is my pick hands down.

Dane - Site Editor - from 2018

Okna 500 InsulTec Deluxe vs. Simonton Relections 5500

I've been on your site getting all the information and now have 2 quotes from A-rated contractors for 9 windows installed. I'm in Raleigh, North Carolina where it's hot in the summers.

Simonton Relections 5500 - $4595

Okna 500 InsulTec Deluxe - $4703

Sue - Homeowner - from 2018

[Site Editor's Answer]

Sue, both quotes look good, and these are both good window series. However, the Okna 500 is better and is only $100 more. This is the route I would go if I were in your shoes.

Tim - Site Editor - from 2018

Okna 500 Basement Windows

I am looking to replace 6 basement windows in my home, which was built in the late 1950’s. The windows were installed with steel frames securing the windows to the foundation. A reputable local contractor has suggested the mid-range Okna 500 series vinyl hopper windows.

These seem to be well constructed windows, better than most others that I have seen. The cost of the windows, including installation is a bit over $800 per window. The contractor claims it will take about a half day to remove the old and install the new. Is this a fair cost to pay?

Thank you for your time.

Glenn - Homeowner - from 2017

[Site Editor's Answer]

Glenn, the “mid range” Okna 500 is an excellent window – a top tier vinyl window to be sure. The price your contractor quoted sounds quite fair to me given the amount of work entailed.

However, I would get a couple more quotes to confirm this. It might help you sleep better knowing you did your due diligence. If local window companies give you a much better quote, you can then ask why he’s charging more than them for the labor portion for the windows.

Up to you of course, but I tend to think contractors may act like you’re being a pain in the arse, but they respect you more and tend to price out other portions of the remodel lower knowing that you might go out and have independent providers/suppliers confirming the bid.

[Glenn's Reply]

Tim, Thank you so much for your response. I appreciate your advice. I have asked for 2 more estimates from area contractors to gauge whether the first estimate is reasonable. Interestingly, the first contractor called me back yesterday and left a message saying he had "great news" which was they can do better on price. Of course, the message did not include what the new price would be and I certainly understand that. It does tell me his price of $800 per window has a lot of fat built into it. I did see a Harvey window on line that would cost approx $500 per window installed. The U factor was 27 versus 25 for the Okna 500. Both are double pane hopper windows and all other specs were similar (insulated frames, metal latches, fiberglass screens).

I will have a conversation with the first contractor to get the details on his so-called great news. I will not make a decision until I have at least 1 other estimate, preferably 2.

Again, thanks for taking the time to respond. It is appreciated more than you know.

Glenn - Homeowner - from 2017

[Site Editor's Answer]

Glenn, good to see you getting that cost bid down to its real price. Harvey makes a good window and $500 per for the Harvey is a good price for the Classic model (I'm sort of assuming its for the Classic). The Okna 500 is the better window, but the Harvey is a solid vinyl window. If you had come to me originally with this brand and price, I would have said to go with this. At this point, it's your call on whether you want/need a great vinyl window or you are fine with a good vinyl window.

Okna 500 vs. 800 Soft-lite Imperial LS

Have trouble comparing: Is the Okna 500 or 800 similar to the Soft-lite Imperial LS. I have quotes as follows for 16 windows:

Okna 500 DS - $523 ea. From ClearView

Soft-lite Imperial LS $531 ea from Window Nation

Vytex Grandview with triple silver glass at $470 each from Window Nation

Any input would be greatly appreciated I am trying to decide today if you could possible respond today.


Sandra - Homeowner - from 2017

[Site Editor's Answer]

Sandra, those are good prices on the Okna 500 DS and Soft-lite Imperial LS. I think they are definitely worth the extra money from the Vytex Grandview. The Soft-lite Imperial LS is the better window from the Okna 500, but not by much. In fact, I would turn from the windows (unless you have a clear preference for one or the other) to the company doing the installation. This would be the deciding factor for me.

The two windows you have quotes on are excellent.

Okna Deluxe 500DX Insultec vs Gentek Sequoia Select

We had researched windows and decided on the Okna Deluxe 500DX insultec only to find out there are no dealers in our area to install them. We live in the Midwest-KC area. In our search we found a company that carries a different window called Gentek. The specific Model is the Sequoia Select BarrierXP TG2. This window has a U-factor 0.23 and SHGC 0.25. This is a triple glass with two surfaces of of low-e glass and two air spaces of argon. Of course, the company owner believes this is the best window on the market.

However we cannot find a lot of current reviews on this window. The cost is $750 per window installed with colonial grids. We have 11 windows total 8 double hung, 1 large picture window and 2 casement windows. This price also includes wood rot repair on several of the windows. Before committing have you had any experience or heard current reviews on the Gentek windows?

Rachel - Homeowner - from 2017

[Site Editor's Answer]

Rachel, you are correct that there is precious little information on Gentek replacement windows, possibly because they are a Canadian based company. Or because they are a building company that sells most of their windows to big builders and not so much through smaller distributors. Whatever the case, I have heard good things about the Gentek Sequoia Select window. However, paying $750 per window for a vinyl window is at the upper end of the cost spectrum.

If it were me, I would keep looking for a couple of reasons. One, you want to get a few bids to see what's out there and what sort of price range you're looking at. Two, it's nice to see, touch and feel different windows to know how sturdy they feel and how well they open, which hardware you like the best etc. And to see if their is a particular installer who has good reviews that may be the best for your project. Finally, you can use the bids (particularly the lower priced ones) to negotiate the best price possible on the Gentek windows if you want to go that route. Here's an article that suggest one way to go about this process.

I would look at our page on the best replacement windows and then google "sunrise windows Kansas City" etc. to see if there are any local companies who service your area.

Okna 500 Window vs Vytex Grandview

I have bids for 24 replacement windows - one for Vytex GrandView windows from Window Nation and the other for Okna 500 windows. Both prices are approximately $15,000. Can you tell me whether one window is significantly better than the other and whether I am getting a fair price? Thanks for your help.

John - Homeowner - from 2017

[Site Editor's Answer]

John, the Grandview window is from Vytex and then relabeled by Window Nation. It's a good window for sure. .26 U-factor and .08 air infiltration rating. Window Nation has a good reputation and sells a good product.

The Okna 500 is an excellent vinyl window, one of the best out there.

If the prices are the same, I would go with the Okna 500 from WoW in a heartbeat. Great window, great installation as far as I've heard.

You should hear some of the horror stories I hear from consumers getting poor windows or poor installs -- issues and headaches for years. Consider yourself lucky or just smart :)

Okna 500 vs Ply Gem Premium

I’m trying to evaluate some of the major brands available in the Kansas City area by their NFRC data on U-Factor and SHGC. I was surprised when I rank ordered data on PlyGem PremiumEP, Soft-Lite Imperial LS and Elements, and Okna 500 and 800, that the Plygem Premium has significantly better U and SHGC ratings than any of the other brands.

Given that Plygem is considered a mid-grade vinyl window and the others are Tier 1, how can this be explained? Should I really be considering a Plygem Premium over these other brands?

I don’t have pricing on any of them yet, that’s coming next week.

In trying to find a quality local installer that could obtain OKNA windows in Kansas City (no dealers locally), I found one that has very high install ratings, but installs solely Plygem. He is willing to look into obtaining Okna product, but is very high on Plygem. Is Plygem really better than your reviews might lead one to believe relative to Okna, Soft-Lite, Sunrise? Or should I really exclude Plygem from my serious consideration and only look at this installer for any Okna opportunities?

Bob - Homeowner - from 2017

[Site Editor's Answer]

Bob, thanks for the question, it is an EXCELLENT one. The nfrc data is difficult to wade through and can be confusing because there are so many ways to slice and dice the numbers. For instance, the Ply Gem Premium window with clear glass gets a .39 U-value, with the HP 2 gets .27, with the Max glass gets down to a .25, and the HP 3 delivers a .22. All based on glass, but no changes to the window frame itself. I try to always compare windows with a basic low-e glass and grids as a way to do an apples-to-apples comparison, but even then sometimes that comparisons are a bit off.

SHGC is the amount of solar heat that is allowed through the window, so this is more a function of your location (you want a higher shgc in cold locations and less shgc in warm climates) and also the direction the window faces -- both places where a good contractor or window company should be able to help you out.

Vinyl windows are tricky because they often look the same and, as you noted, the NFRC values can be very similar depending on the glass packages. Where the differences lie is with the the manufacturing tolerances, the rigidity and overall strength of the extrusion, as well as the long term manufacturer's reliability.

Ultimately, I think the best performance number to compare is air infiltration or air leakage. The Ply Gem Premium is a good window, but I believe their air infiltration is something like .08 to .12 (I may be a bit off, if you know the exact number do let me know). The Soft-Lite Imperial LS is .02 and the Elements is .01, the Okna 500 is .02 and the 800 is .01. I typically say .10 or lower is good, .05 or lower is great.

The bottom line is that the Ply Gem Premium is a good window and I like the fact that the local installer has a good history with the window, installs it a lot, knows who to contact if their are issues etc. I still think that most industry experts would rate the high end series of Soft-Lite and Okna above the Ply Gem Premium and I feel that the AI number bears witness to that. Quality of the installer though has to play an important role in your decision as well.

Okna 500 vs Thermal Industries 5000 Series

Hi - my builder - who I completely trust and over all the years working with contractors on many houses I've owned he is one of the most thorough and detailed I've found. He takes care of all my siding and wood replacement and installed new roof and has built new porch and deck and many things. When any wood rots on the house he replaces with non rot pvc. (Like the Masonite siding to hardie plank)

The house was built in 1991 and I have replaced nearly everything on the house now. The last big thing I have now is all the windows. Due to money I will have do the windows in stages doing 6 or 7 at a time. The existing windows are double hung wood windows with 1 inch old style pull out grills and exterior wood trim. Scott said the best route is to replace all exterior trim to pvc and use ply gym vinyl sash replacement kits. (They can do 1 inch contoured grills) that way I won't get any glass loss compared to using pocket replacement windows. Cost per window for all that is around $600.

I don't like the idea of pocket replacement windows and have had many estimates from contractors for those. My favorite of those is a guy who will replace all exterior trim to pvc and use thermal industries 5000 series 1 inch grills. Cost is around $450 per window all in.

The best window guy I've found though is a window contractor who refuses to do pocket replacements...he will only price for full frame and believes that pocket replacements are bad news. He replaces all exterior wood trim to pvc and also does all new interior wood trim. This looks like a great thorough job but it will be more mess on the inside of the house than using my builders method. He proposes to use okna 500 series windows and for all exterior and interior trim with window it's $660 per window. Many thanks .

Rowland - Homeowner - from 2016

[Site Editor's Answer]

Rowland, sash replacements can be a mess, unless the installer really knows what they are doing and has some experience putting in sash replacement. If it were me, I would go with the full frame and the best window in the bunch -- the Okna 500. At $660 per window, that's a pretty great price for all that that entails.

I did take a look at the performance numbers of the Thermal Industries and I was impressed with those, but again I think it's worth the extra money to go with the more thorough approach, especially considering it sounds like you will be living here for a long long time. Although I have to say that $450 per window is a pretty good price :)

Ply Gem makes a pretty good window -- they make a number of models so I'm not sure which is offered in the bid. I think I'd put the Ply Gem below the other two options you have though.

Okna Insul-Tec vs Soft-Lite Elements

My neighbors have chosen Okna Insul-Tec for replacement windows in their 20-year old homes. We live in the south central region of the U.S. The same company offers Soft-Lite Elements for a few hundred dollars more. I'm confused with all the numbers, ratings and online rants. What's the best choice? I'm only doing the front of the house at this time. Thanks for your guidance. Enjoying the read.

Natalie - Homeowner - from 2016

[Site Editor's Answer]

Natalie, the Okna Insul Tec is quite a good vinyl window, but not as good as the Soft-Lite Elements in my opinion. The Elements is more or less the best vinyl window out there (the Okna EnviroStar or 800 series is equal to the Elements). If the Elements is only a few hundred more, I think it's worth it. The bottom line is that either way, you are buying an excellent product and assuming you have good installation, you should be well served for a couple of decades at least!

Okna 500 Series vs Andersen Silverline 9500

Hi Tim. I was looking to replace 7 55 yr old double hung windows in my house in north/central NJ. Was about to buy Andersen Silverline (9500 series), but after reading your website I thought I should look around some more.

Any suggestions for other options in my area? I am currently working with a contractor on a kitchen remodel, so if I need to purchase the windows through his account if not offered directly to the consumer, that's not an issue.

Mike - Homeowner - from 2016

[Site Editor's Response]

Hi Mike, I'm not quite sure what he has access to, but my top four vinyl window manufacturers on the east coast would be Okna, Soft-Lite, Sunrise, and Polaris - in that order. The companies are going to be more expensive than the Silverline for sure, but I always point out that from a long term basis, you will usually save money by going with a high quality brand coupled with proper installation. Each of these companies has a number of models they sell, each of which has a different price point. I typically recommend going with the mid range option to get the best value for your dollar - so the Okna 500 model, the Standard Sunrise, the Soft-Lite Pro or Classic and the Polaris ThermalWeld.

Let me know if any of these recommendations works out!

Okna 500 vs 800 Series

The contractor reviews say the Okna 800 is one of the very best windows. The U value is .36. The 500 U is .25. Seems like the 500 would be a better choice. What am I missing?

Mark - Homeowner - from 2015

[Site Editor's Response]

Mark, there are so many variables when it comes to testing windows that it's easy to see numbers(especially online) that sort of spin the truth one way of the other. Check out the nfrc.org website. Go to verify ratings, residential, search by manufacturer - compare the Okna 500 vs 800 against one another and you should see very similar numbers. The U-factor on their standard low-e glass should be MUCH less than that. The 500 is an excellent window and honestly probably the better value. The 800 is a top of the line vinyl window that will have similar numbers, if anything just slightly better numbers.

Tim - Site Editor - from 2015

Okna 500 Series vs Sunrise Windows

I have quotes on Sunrise windows classic and Okna windows 500. The Oknas are $300 cheaper. The Sunrise guy told me that the glass they use is better than Oknas. Is that true?

Nat - Homeowner - from 2015

[Site Editor's Response]

Nat, off hand I don't know what glass Okna uses, but I've never heard it pitched as better than Sunrise. I would assume that pound for pound the Okna 500 would perform a bit better than the Sunrise "Classic." The bottom line is you have to very good windows to choose from. I would choose the company that I thought was going to do the better install instead of selecting based on the window.

Okna 500 Double Hungs

I'm currently looking to replace some old steel casement windows in my home, which was built in 1950. I was interested in the Okna 500 series in the double hung style, but the only local dealer in my area which carries Okna windows only seems to deal the 400 and 800 series. While looking at the 400 series display in their showroom, it looked to me that the 400 series features an interior weeping system, but the brochure they gave me on the 400 series features a picture of the double hung which appears to have holes in the exterior sill for external weeping (not sure if that's the correct terminology) and it doesn't explicitly state anything about the weeping system. I'm thinking either the dealer's display model was old/outdated or that the picture in the brochure was not of an actual window.

Does anyone know which type of weeping system the Okna 400 windows use?

Jason - Homeowner - from 2015

[Site Editor's Response]

Hi Jason, it's interesting you are having an issue finding the 500 Series, someone else just mentioned having the same problem, not sure why the local rep would not carry their most popular replacement window model. You may want to submit your information to their website and see if any additional dealers are available in your area. The best way that I can explain this is that the weep holes on the 400 Series are secondary drain paths. The window has a 1 piece sloped sill that properly drains most or all of the water and is the best sill system on the market. The weep holes on the 400 are there as a sort of conduit for water in the event of sustained rain.

Okna 500 vs Harvey Windows

We're replacing 35 windows in our PA home. My contractor is pushing the Harvey Tribute, but I like the Okna 500s and 800s. I think they're better as far as performance, ratings, and looks too. Then today I saw a Tribute that was loaded with options and features, grids, triple pane, self cleaning, krypton, etc. I was quoted $390 installed, which seemed like a fantastic price. Some of the windows are smaller, and would be a little cheaper. I want a good window, not just a cheap one, but I don't want to spend more if it isn't a lot better.

Max - Homeowner in Pennsylvania - from 2012

[Contractor Response]

The 500 is one of the best windows out there. I wouldn't call the Harvey bad, exactly, but they aren't even close to the Okna 500. Your price is going to vary a lot from dealer to dealer and installer to installer. I'd find the dealer that offers you the best deal, but you don't want an installer that's going to cut corners and do a slapdash job. You have to be willing to pay a decent price for the install. A great window put in badly will be a mediocre window in terms of energy efficiency.

Harry - Contractor in Wisconsin - from 2012

[2nd Response]

The Harvey Tribute is a decent window, but it can't compare to the Okna. The Okna 500 has a U-factor of .25, DP structural rating of 50, and air leakage is somewhere around .02. The Harvey has just OK numbers - U-factor .30, DP 30, and over 0.1 for air leakage. The Harvey loses in every way.

Okna 500 vs Soft-Lite

I've looked at so many windows I'm sick of them. I have 16 windows to replace and I've managed to narrow it down to the Okna 500 Insul-Tec and Softlite Imperial LS. The quotes I got were $9680 for the Oknas and $9920 for Softlites. Any opinions on which is better?

Rob - Homeowner - from 2012

[Contractor Response]

They are both great options that will last a long time. With a fairly close match I would probably let the installer be the deciding factor. Either window should last a long time and not give you any problems.

Holland - Contractor - from 2012

[2nd Response]

Both of them are great choices. The Soft-lite is always a good deal, they're a good company and have some good options, I realty like their Edgetech Super Spacer. They are also simple to reglaze if you need it. The Oknas are also really good, reliable and nice. I'd pick the one whose installer you like best.

Okna 500 Windows Reviews

I've been looking into Oknas and I've found out a lot of info. The Starmark has a thicker frame and I don't like that so much. The 500 and 800 are very similar as far as the frame goes. The 800 has smaller lifting rails (I think they look nicer than the 500) and it has a magnetic seal which I like. My biggest problem with the 500 is that you can see from the outside if it's locked or not. Basically, I like the 800 better, but it is also more expensive. It isn't much in terms of cost and I think the difference is worth it. Also, the 800 I was looking at qualified for a tax credit, but the 500 didn't, which kind of makes up for the higher cost.

Okna 600 Windows Reviews

The Okna 600 Eco Pro is the company's newest window that uses a slightly less robust extrusion than the other Okna models. It has fews bells and whistles, but it looks pretty similar to the 500 and has the same foam inserts, weatherstripping, standard glass and locking mechanism. The window is overall well built and delivers very solid performance numbers.

OKNA 00 Eco-Pro Quote

I live on top of a mountain and need to replace my windows. I'm in the middle New Hampshire. I just got a quote for OKNA 00 eco-pro for $1000 per double hung window installed.

$1k for all size windows was a joke as was the salesman's knowledge of building practices. I contacted a neighbor(contractor) to see who he deals with. Thanx for the help...my wife said keep our windows as is and buy a boat!!

Wayne - Homeowner - from 2018

[Site Editor's Answer]

Quite a good window, but quite a steep price tag. I'm not quite sure which companies are available in your area but I'd suggest you google, "sunrise windows in [your town], new hampshire" and see if any local companies come up. Do this for Sunrise, Okna (which you already did), Soft-Lite, HiMark, Kensington, Vytex, Zen, and Polaris.

Hopefully, you can get three bids to actually compare because you need to see if the $1K per window is because of how complex your project or if it's just an Okna rep trying to see how much you're willing to pay.

I went to the Sunrise website and did a zip code search and came up with a company on the Mass border. You might want to call them up and see if they'll give you a bid or if you're outside their area.

To answer your Window World question, they are on the lower end of the spectrum, both quality and price wise. Some WW brancehs have good reputations and others have very poor reputations. I would tred lightly when it comes to WW myself, lots of things can go wrong with the windows come years 7 and beyond.

Okna 600 Window Bid

Getting 10 normal windows and 2 sliders. One for kitchen sink window and 1 3 slider replacing bay window. The bid on the Okna 600 window is $12,250.

I'm feeling that's even high if they were 800 series! Please help me.

Steven - Homeowner - from 2018

[Site Editor's Answer]

Steven, that does potentially sound high, although the XOX slider would obviously run quite a bit. However, I can't honestly tell you whether the bid is definitely too high or not. The only way to tell is to get a couple more bids. Comparable companies to Okna include Soft-lite, Sunrise, Polaris, Zen, HiMark, Kensington, Alpen, and Vytex.

If you still like the Okna window after you get the other bids, take a lower priced bid to them and ask them to match it. Also here is an article that talks about how to negotiate a window bid to find the best price.

Okna 600 Windows vs. Alside Mezza

Hi, We just bought a historic home with 38 beautiful wood, lead lined, windows (most are casement, with just a few double hung). Unfortunately, they have not been cared for, and most of the wood is rotted. This is our first home, and we don’t really know where to start. We are planning on just replacing the ones in the back to begin with, so don’t necessarily have to replicate the look exactly.

And we have been given quotes that span the prices - from Renewal by Anderson at $80,000 to Alside Mezza for about $15,000 (keeping some casement and doing double hung for the rest). With the Alside, the double hung are quoted at $375 a window, including full grid pattern and installation.

At this point we are completely lost as to what to do. We were leaning towards just going with the Alside Mezza and doing the back of the house to begin with. The company (NewVue) and their installers have great reviews in the Cincinnati area, and they have lifetime installation warranty. However, after doing research, it seems that most people do not have great reviews of Alside Mezza.

Are we naive going for the Alside Mezza because of what feels like a great price? We haven’t seen it in person, and are also nervous about ruining the look of the house by just going with a window that will look cheap.

Do you have recommendations for reasonably priced windows that look good in historic houses? We can’t seem to find a middle ground in terms of aesthetic and pricing.

Catherine - Homeowner - from 2018

[Site Editor's Answer]

Catherine, so your two bids are more or less on the opposite sides of the window price spectrum. The Renewal bid is at $2K per window and the Alside Mezzo is $375 per window. I think you need to keep looking. The Mezzo isn't a bad window, but I'm not a fan of the pocket sill or the overall strength of the frame. I think you can get a MUCH better window for $500 to $600 per window.

On the plus side, Ohio has lots of options that will offer better energy efficiency and durability at a competitive price -- again, I'm hoping in the $500 to $600 installed range. So Okna windows should have a local dealer in the Cincinnati area. They have a 600 series that is not quite as good as their 500 series but might work price wise. Their 500 series Insultec option is quite good and their premium 800 series is one of the best vinyl windows on the market. Each of these models comes in an interior wood laminate that is pretty tough to tell apart from real wood except at close range. The performance data on any of these is going to be far superior to any wood clad window.

Sunrise and Soft-Lite also should have dealers in your area and these two companies, along with Okna, are the three best vinyl window companies out there (in my opinion). So they all carry a number of different window series from entry level to premium. With Soft-Lite and Sunrise, I would love to see you NOT go with their entry level window, but their mid range offerings are very good and the dealers should be able to order all of them in an interior wood laminate that hopefully will work with your historic house requirements and aesthetics.

If and when you do get bids from them, send them over to me and I'll be happy to take a look and tell you which one is offering the best deal.

Good luck and congratulations on the new purchase!

Okna 600 or Soft-Lite Classic In Cincinnati

Dane,I need some direction. I should replace my Anderson wood windows, barely double pane windows original to my Cincinnati, OH, 1982 home as I notice some dampness in the more SW facing windows near the glass. They also create a lot of heat in the summer, and I’m sure AI in the winter. I’m looking to replace them with vinyl windows as my home is mid-range not high end.

I have 18 windows. 6@ 32”x67” and 7@32”x50,” and the remaining are smaller sized.

I received a quote for Prolite Elements windows for $11,886. I don’t know if that’s a good quote? I’m not sure I want to spend that much. I don’t know if I’ll be in the home for more than 5-10 yrs.

Which mid-range window would be the best value to investigate? I think I have several options here such as Polaris, Zen, and others.

Thank you.

Melissa - Homeowner - from 2018

[Site Editor's Answer]

Melissa, so the Soft-Lite Elements is an excellent vinyl window, one of the very best on the market. $660 per window for the Elements is a very fair price. However, if you are only going to be in the house for 5 to 10 years, you probably don't need to get a premium vinyl window. For instance, you could go back to the Soft-Lite dealer and see what he would charge for the Classic or Pro models. These are both good vinyl windows, great for your purposes, but should be more in the $500 to $550 per window price range.

You could also get a bid from an Okna dealer on their 600 series, which is a very solid vinyl window that should be in that same range. You should also consider Sunrise windows as well, their Standard series is quite a nice unit. You are correct that Zen (they sell Soft-Lite relabeled windows) and Polaris also make a good product.

The bottom line is this: a good solid mid range vinyl window from one of these brands should be perfect for your window replacement project. Get a couple of bids and see how they stack up to one another. I'm happy to take a look and give you my opinion on what your have.

OKNAEco-Pro 600 or PROVIA Endure Windows

Hello, which is a better double hung window...OKNA Eco-Pro 600 series or PROVIA Endure windows?

It is going to be very expensive. Six of the windows are large...35 by 70. Eight are 35 by 58. Three are 34 by 50. Two are 33 by 40. Three are 33 by 70. Three are 21 by 43. One is 31 by 52..........26 windows all together. Provia Endure estimate is $19,491. The OKNA Series 600 Eco-Pro estimate is $20,544.

I am still waiting for the estimate on the OKNA series 500 to come in ( also how the 3rd company will install the windows). I do want them to remove the siding and remove the old flange and install new and then replace the siding. What do you think. Right now I have builder grade windows (Farley windows).

Mary - Homeowner - from 2018

[Site Editor's Answer]

Mary, those bids are pretty good considering all of the siding work that is involved. You are right to do the job correctly and get it done properly. I think I would pay the extra for the Okna 600. I like the Okna 500 more but 600 is still quite a good window. Let me know how the project turns out and good luck!

ONKA ECO-PRO 600 Series Quote

I have a quote for ONKA ECO-PRO 600 series. It is for 10 windows including installation for $9,9093.30. Is this a reasonable quote or do you think this is high for 9 windows.

Mary - Homeowner - from 2018

[Site Editor's Answer]

Mary, this is an expensive quote, although I don't have any information on the details. I would absolutely recommend getting a few more bids to see how they compare.

Search for Sunrise, Soft-lite, Polaris, Zen, Vytex, and Wincore. I listed these vinyl window manufacturers in order from best reputation to good reputation. Find the local companies that carry these brands, call them up, and get a few free bids. Make sure to tell each one that you are comparing bids and that you would appreciate their best bid at the start.

Okna 600 Window Series vs. NEBP Trustguard

How does Okna 600 replacement windows compare to Trustguard?

Jackie - Homeowner - from 2018

[Site Editor's Answer]

Jackie, the NEBP's Trustguard window is decent; it's essentially the drop down or step down from the Crusader series that they sell. All in all, a decent but not great vinyl window.

The Okna 600 Eco Pro is an excellent window, with performance numbers to back it up. The Okna is the better brand and the better window. Now, how do the installers match up? Okna usually uses well respected local dealers, but NEBP's has a solid reputation as well. Assuming the installation quality is the same, the Okna 600 wins hands down.

Okna 700 Windows Reviews

The Okna 700 window is the company's casement and awning vinyl window styles. The 700 Okna is considered a very good vinyl window.

Okna Casements vs. Simonton 5500 Series

We have 14 windows that need to be replaced. I looked at the Simonton 5500, which was nice, but really bulky. I looked at Okna casements, but they are $12,500, which is way over my $10K budget.

I'm waiting to get a bid from Ply Gem and Sunrise windows.

Jeff - Homeowner - from 2015

[Site Editor's Response]

Jeff, the price quoted on those Okna casements is pretty darn high. I agree with you that Simonton Windows are fairly bulky.

Sunrise makes a good vinyl window that is slimmer, but is going to be similarly priced to the Okna.

Ply Gem windows are on par with Simonton and the Ply Gem premium window is a good option that should be less expensive. Not sure how it compares frame thickness wise, but definitely worth a look.

Okna 800 Windows Reviews

The Okna 800 EnviroStar window is regarded as one of the top vinyl windows available. The Envirostar is very popular, with a frame thickness of 0.80, which makes it very durable and strong. The U-value is 0.25, SHGC .30 (without grids), condensation resistance 62, and air infiltration is 0.01. This AI cannot be beat -- literally it's as low as you can get.

The Okna 800 series differs from the Okna 500 series in the following ways. The 800 gets a .01 AI (the 500 gets a .02), the 800 has a magnetic seal along the bottom of its lower sash (the 500 does not), the 800 uses a metal lift rail (the 500 uses a vinyl lift rail), the 800 allows consumers to upgrade to a brass or nickel harware (the 500 does not), and finally the 800 offers SDL (simulated divided light) while the 500 offers only internal grids.

Okna 800 is one of the highest priced vinyl windows on the market and with good reason. This is the window I would put in my house if I could afford it. The Okna 800 is available in a variety of colors and finishes for both the interior and exterior, plus some excellent hardware options including brass.

OKNA 800 vs. Harvey Tribute

Hi, I'm looking at the Okna 500 and Harvey Tribute series for our colonial comeback east. I was wondering which window you would recommend between these two. Would you recommend I upgrade to the 800 if I do go with the Okna option?

Thanks for your time!

Jim - Homeowner - from 2019

[Site Editor's Answer]

James, between the Okna 500 and Harvey Tribute, my pick would be the Okna 500. It's the better window in my opinion. The Okna 800 is an excellent window, with a few nice upgrades. I would get a bid on both and have the sales person point out the little differences between the windows. Once you see them and the price difference, you can make the decision on whether you want the upgrade or not. The 500 is an excellent window though. The 800 is even better.

Okna 800 vs 500 windows

Dear Tim, I am replacing 9 double hung Windows i have a price that is $50 a window higher for the 800 than the 500. Is the $450 worth paying for the 800? Please advise as to your thoughts. Thanks Rick

Angela - Homeowner - from 2016

[Site Editor's Answer]

Rick, $450 for the Okna 800 is kind of ridiculously low. I usually expect this window to run more like $650 to $700 per window. Yes, the 800 model is worth an additional $50 over the Okna 500 model. Both are excellent vinyl windows, some of the best in the business.

I almost hate posting this to the website because other consumers might expect to get Okna windows at this price. If the deal is from a reputable dealer with a good track record for installation, I would jump on it!

Tim - Site Editor - from 2016

Okna 800 vs Marvin Integrity

Hi Dane, Love your website! It is very helpful. Question: Would you go with Marvin Integrity over one of the high end vinyl replacement options from Okna? Even though Integrity only has a 10 year warranty (from what the salesman told me) I am leaning toward it. I live in Washington DC where we get both warm and cold weather. Maybe that is crazy and I should just choose the one with the lifetime warranty like the Okna.

I would love to buy Infinity (life of the home warranty) but they are quoting $48,000 for that line versus $28,000 for Integrity.

Angela - Homeowner - from 2016

[Site Editor's Answer]

Hi Angela, I would go with high end vinyl window like Okna over the Integrity. The performance data is going to be much better on the Okna 800 than the Integrity or Infinity. I agree that the Infinity is the better window, but not for almost double the price. That's crazy. If it were me, I'd get a bid on one or two of the high end vinyl windows like Okna 800 and Soft-Lite Imperial LS or Restorations and compare the cost, overall look, and all of the performance data to the Integrity. This should give you enough information to make a much more informed decision.

Tim - Site Editor - from 2016

Okna 800 vs. Marvin Infinity

I have found your website very helpful, and appreciate the advice you offer. We are in a traditional colonial with wooden (1990's) oriel windows. One broken window, a few difficult to open, and no tilt in feature have me in the market to replace. I have narrowed to Okna 800 series for high end vinyl, and Marvin Infinity...both are highly rated on this site. Cost is significantly higher with the Marvin (9K for 8 double hung) vs under 5K using Okna. I'm sold that Okna is an efficient window, and it is nice looking with an upgrade to metal hardware. I am simply concerned about losing glass space and overall appearance in comparison to my existing wood.

Of course the Marvin rep says his window would outperform vinyl in resale, appearance and durability. I know that windows are a great and worthwhile investment, but I am still undecided if better to invest in the much more expensive Marvin Infinity line or in the very highly rated Okna vinyl. Both seem to have solid warranties. Any input on these...or would you steer me to another brand that supplies northeast Ohio?

Lisa - Homeowner - from 2016

[Site Editor's Answer]

Hi Lisa, I think you have two very good options here in the Marvin Infinity window and the Okna 800 window. I would say that the price difference definitely warrants going with the Okna -- I think the loss of glass area would be very minimal between the two. One option you may want to ask the Okna rep about is an upgrade to an interior wood grain laminate -- Okna makes a very nice one that looks quite similar to wood, but without the requirements of wood.

In terms of performance, the Okna 800 is superior to the Infinity by far. The Infinity is quite a nice looking window in my opinion, but the Okna with the interior laminate and the metal hardware is pretty tough to beat.

As far as resale value, I can't see that being much of a factor. Keep the performance numbers handy on the Okna (especially the .01 air infiltration number) and hand it to the potential owners and tell them that they are buying a house with the most energy efficient windows on the market -- just leave out the vinyl part, it's got to one of the least sexiest words in the english language!

Okna 800 vs Soft-Lite Pro Windows

I have been looking for replacement windows for a vacation home I have in Franklin, NC. I do not want to buy them at a big box store. And I have my own installer. I am considering the Affinity Elite series, Soft-Light Pro series or a similarly quality product. I need excellent protection from the cold. I have been unable to find where to purchase them from directly. Could you please help me with information of where to purchase a good window? Thank you for your help

Cynthia - Homeowner - from 2016

[Site Editor's Response]

Cynthia, the Soft-Lite Pro is a very good window. Can I ask you about the Affinity Elite, because the company is now out of business and if you have access to their windows, I'd love to hear about it because I have a homeowner who wants to finish up her house with these windows (she used them for ½ and then stopped the project) but now can't find them. Having said that, if I were you, I would NOT use the Affinity Windows, although your contractor may be giving you a great deal because the company is no longer making the windows (obviously I don't know the details).

If you already have an installer, have him call up Okna and see if he can get the 500 series or the 800 series. Or call up Sunrise and see if he can get their standard Sunrise window shipped to you. Some companies are willing to ship like this. Polaris also makes a great window.

It is true that many window companies may not be willing to do this and go around their reps, but it doesn't hurt to ask. I know out here on the West Coast, Home Depot carries the Andersen 100 composite window, which I think is a decent window, almost on par with the Soft-Lite Pro. They sell it for a very good price and with a meeting rail reinforcement and glass upgrade, I'd certainly consider this for my house. Especially if you have an installer that you like.

Dane - Site Editor - from 2016

Okna 800 Series Enviro-Star

On the 800 Series Enviro-Star are they Foam Filled? Do they make custom size windows? Does the customer have to ask if they want foam filled Vinyl windows? Are the 800 series argon filled?

Raymond - Homeowner - from 2015

[Site Editor's Response]

Raymond, the 800 series is a fantastic vinyl window, probably the best there is. The company offers a Deluxe option on any of their window models that includes the foam fills and a locking screen. Probably worth the extra money, perhaps an extra $50 to $75 per window.

You should be able to custom order your windows for the local Okna rep, who will come to your home, measure all your windows, and order each window to fit your existing openings.

Good luck and if you think about it, get back to us after your windows are replaced and let us know how your project went so we can report back to other consumers!

Tim - Site Editor - from 2015

Okna 800 Windows Reviews

I don't think there's much question that the 800 is one of the best. I'd certainly consider it among the top 4 or 5 vinyl windows out there. The double pane window has a U-value of .25, air infiltration .01, and DP of 60. That beats pretty much any of their competitors. They definitely beat Simonton, although Simonton has really good customer service. The Simonton is a solid window that won't give you any trouble, but they aren't exciting. Oknas have the features and options to push it up to a higher class. They are more like the Sunrise, Gorell, and SoftLite.

Okna 900 Starmark Reviews

The Okna Starmark window has a thick frame, which makes for a strong and durable window, but also means less glass area. It is considered one of the best composite frames, but home owners with smaller window openings might prefer something with more glass. This model is comparable to a Renewal By Andersen, although the Okna often gets better reviews at a lower price. See more Renewal By Andersen reviews.

Tim - Site Editor

OKNA Starmark Project

Hi Tim, last year I replaced 7 windows in my 2 yr old townhome in Gilbertsville, PA. Original PlyGem windows were OK but the install was terrible...drafty, etc. The Volpe Enterprise installers removed all of the siding, removed the PlyGem window, installed the replacement (not new construction) OKNA Starmarks, put ‘pink’ insulation around the frame and caulked inside and out. The windows were installed from the outside making sure that the house wrap was completely taped off. Only inside work involved caulking. The first winter proved that OKNA was a good investment as my home was draft free and comfortable. I paid, on average $850 per window.

I have 5 remaining windows needing replacement. However, the original installer just gave me a written quote of $5756. OUCH!

Last week, another independent installer quoted me $3835, however the quote specifies that the windows are installed from inside the house. They do not remove the siding; they use spray foam as insulation.

Although the pricing difference is significant, my fear is that the independent installer is cutting corners by his installation method. He too quoted replacement, not new construction, windows.

My question for you: what installation method is more effective and why?

I appreciate your response. Thanking you in advance.

Clare - Homeowner - from 2018

[Site Editor's Answer]

Clare, there is no single answer to your question, "what installation method is more effective and why?"

Full replacement is a more complete method and more expensive and often saves a little glass area. The siding removal and replacement makes this a more expensive process.

Retrofit is a less invasive method, but you will lose some glass area.

I think the real question is the condition of the frames of the original windows. If they are in decent shape then you can do retrofit and it can be a good method.

>It's hard to sort of diagnose through the internet. Best way to know what the proper method is -- get more installers to come out and give you their opinions. At some point, you will have enough opinions where a consensus is formed as to what method you should use. Then pick the best installer of the bunch :)

Okna Starmark vs. Sunrise Restorations

Hi, we have a 30 year old home that needs 36 replacement windows and one sliding patio door. We have four bids that are all over the place.

Okna 500: $28,600

Okna Starmark: $33,000

Soft-Lite Imperial LS: $46,550

Sunrise Restorations: $53,000

Is there one quote that stands out from the others?

Kristen - Homeowner - from 2018

[Site Editor's Answer]

Kristen, the Okna bids are less expensive and still provide you with an excellent window. The only question you have to decide is whether the composite frame is worth an extra $4400. The Okna 500 is very good and the Okna Starmark is the best composite frame on the market. Either way you can't go wrong!

Tim - Site Editor - from 2018

Okna 1800 Starmark Reviews

The Okna 1800 series is the top-of-the-line 800 series in a triple pane glass. The low-e glass it comes with contains 22 layers as opposed to 11 with the 800 series. It has a U-factor if .18 (the 800 has a .26 U-value), a .25 SHGC, an air leakage of .01, and a condensation resistance of 75 (up from 62). It is truly an exceptional vinyl window. Expect to pay $100 more for this upgrade per window.

Okna 1800 Bid Review

Hey Tim, thanks for running such a great website! After buying my parents home from them, I’m tasked with replacing their 20 year old windows. I received the attached bid for replacement in the northern VA area. The salesman educated me on all the window rating factors and since I’ll be in this home for the next 20-30 years, was leaning toward the OKNA 1800s. Any thoughts on this and the pricing?

Many thanks!

Brian - Homeowner - from 2018

[Site Editor's Answer]

Hey Brian, thanks for the kind words. So the company you got the bid from is a well known company with great reviews and a great track record...so they aren't going to be the cheapest in town. But they are going to give you great service, a really great window, and they'll be there for you if something happens down the road. Trade offs, right?

So $700 per window for the Okna 500 is a decent price. $778 for the Okna 800 is a decent price and same goes for the triple pane 1800. You definitely are not getting taken to the cleaners as they say.

You might ask if they'd be willing to give you the Okna 800 for the $19140 that they offered you for the 500 series. Or the 1800 for the 800 price. I'm not quite sure how willing these guys are to negotiate, but it can't hurt to try. I think if they had a gap in their schedule they wanted to fill it. I'd ask for it and if they say no, thank them and wait for a few days to see if they change their mind.

I'd love to hear what happens so please let me know how it goes!

Okna Elegante Windows Reviews

Okna Elegante Patio Doors

Thank you for all the information on your website! I am looking to replace a sliding glass patio door and have received 3 quotes (ours is a custom 5.5 ft door) - $4500 for a Renewal by Andersen, $1900 for an Alside (he simply referred to it as "turnkey"), and $1998 for an Okna Elegante. Does a company's reputation/reviews on their windows translate to the quality of their doors? Do you have any thoughts on these three companies regarding their door quality and these prices? Based on my own research Okna seems like the best value, but there is so much information overload out there I'd love to hear your input! Thank you!

- Homeowner - from 2016

[Site Editor's Response]

Sara, while window quality does not always translate to doors, although generally it does. Let's start with the Renewal quote. Renewal makes a good door but as you have probably surmised it's expensive. In my opinion the renewal windows and doors are too expensive for what you get. Especially with the Okna Bid.

Alside manufactures an okay patio door but at the same price as the Okna Elegante, it really isn't a contender in my opinion.

Okna manufactures very good windows and doors and this is the option I would go with. Without hesitation.

General Okna Windows Reviews

Okna vs Alside Fairfield 80 Series

Just found your website. We are replacing 8 aluminum framed single paned windows. They are all 48 x 72 inches. The top part are picture windows with an 18 inch awning type window on the bottom. 5 are second story windows above a large deck with 3 windows at deck level.

We have a quote from an Alside dealer using Fairfield 80 triple pane widows with a bottom slider. The quote is $8730 complete with installation. That seems very high to me so I am doing some further research.

You seem to like Okna windows. Don’t know if they are available in Oregon. Would you have any suggestion for our project. From online searching it appears that Alside windows are not highly regarded. Thanks for any help.

Chris - Homeowner - from 2017

[Site Editor's Answer]

Chris, I am not a huge fan of Alside windows, but some people think they are decent. I feel like they are more of a builder grade window and paying over a $1000 per seems a bit crazy to me -- although the awning window at the bottom throws a pretty big monkey wrench into that calculation.

Okna is definitely not available in Oregon. Milgard vinyl windows are a good quality and they should be available. Marvin as well, but they aren't cheap.

Amerimax may be available and they are solid for vinyl. Jeld Wen makes a wood clad window with an Aurlast wood treatment that comes with a lifetime warranty that I've heard good things about. I normally don't recommend Jeld Wen or wood, but the lifetime warranty is impressive.

To be honest, the west coast doesn't have the same quality vinyl window manufacturers as the east coast. However, we also don't have the extreme weather that they do there -- although Oregon obviously gets cold and wet in the winter.

Okna Windows vs Sunrise Verde

I live in New Jersey and need new windows and good ones at that. There are two options we are looking at, the Okna 800 and Sunrise Verde. There are some subtle differences between these windows and was wondering if you have any advice or suggestions.

We 1 octagon shaped window and 6 other double hungs. Both quotes are $3800.

Thanks in advance.

Sonnie - Homeowner - from 2016

[Site Editor's Response]

Sonnie, you have two excellent vinyl windows. Honestly, yes there are differences between these two windows, but both are very good. The quotes sound very fair. I would turn to the question of installation at this point as my deciding factor.

Tim - Site Editor - from 2016

Okna Windows vs Harvey Classic

I bought an old house in Boston that we are working with a contractor to renovate. We're hoping to move in this fall. Half of the house has been gutted.

The original part of the house is ~1850, and later additions seem to be 1880s-1910s. There are about 26 windows in the original part of the house that match in style but are slightly different sizes in different rooms. Then there are another dozen windows throughout in the newer parts of the house of varying sizes and styles. Almost all seem to be original to their time periods. About 80% are 6 over 6. They are all covered with aluminum triple track storms that are in fair to poor condition.

We were going to restore the windows ourselves, but it has turned into too big of a job with the time available before we can move in. We have removed all of the windows already. Our contractor says he can teach us to install replacements so we can save on installation costs.

I am disappointed to lose the the original windows, which are part of the charm of such an old house. But I am excited to get rid of the ugly aluminum storms and have a window I don't have to maintain. I looked around but the prices I'm getting for historically accurate simulated divided light windows are pretty high. Heirloom windows makes a very accurate window that has the efficiency and maintenance benefits of a modern clad window, but we got quoted $1000 per window.

Our contractor wants us to buy Harvey windows at $290 per opening. I'm assuming these are the Harvey Classics, but he hasn't said.

There's a nonprofit building services place down the street that also recommended Harvey. They have the Classics at $300 per opening and the Tribute at $352 per opening. They've suggested we upgrade to new construction windows in the part of the house that has been demo'd, which adds $40 per window. Harvey can add 3-part SDL for $119 per sash, but that's quite a lot of money for a purely aesthetic touch. If I buy from them this month I'll get 5% off.

Overall, I'd like to keep the price to $300-$400 per window if I am going to do the installation ourselves under our contractor's guidance.

My questions:

1. At this price range, should we go with Harvey or get something else? Is the extra $60 per window to go from the Classic to the Tribute worth it?

2. Is my contractor marking up the windows? I don't mind, since he needs to make a profit and is cutting us a lot of slack. I just want to know before I shop around since if I buy elsewhere I might end up taking money from his pocket and may need to work that back into the budget elsewhere.

3. Does it make sense to do the new construction windows where we're down to the studs anyway? What exactly is the difference? Do we get new jambs, sill, stoop, etc.?

4. Is there a decent simulated divided light window with a true 3-part muntin profile available in my price range?

Jason - Homeowner - from 2016

[Site Editor's Response]

Jason, the Harvey Classic and Harvey Tribute are both very solid mid range vinyl windows and the price you are getting quoted is very good. I can't say whether your contractor is marking them up, if he is, not by much. I think it makes sense to do the new construction where possible, the only real difference is the nail fin that comes with it and allows for more secure installation along the header and sides.

Are there better windows out there? Absolutely, but not many in the $300 to $400 range. This is actually a pretty low price range for replacement windows. One option you can consider is looking at Sunrise or Okna windows that use a laminate woodgrain on the interior - both of these companies make excellent vinyl windows and their laminates are pretty realistic looking. The two problems I see with this though is finding someone who will sell you just the window (without the installation) and the cost. These windows are going to be in the $400 to $600 range just for the window itself, depending on the glass, interior options, hardware, SDLs etc.

The reason I suggest at least taking a look is that you live in an area that gets some pretty severe weather and long term I think you would save more by going with a top end vinyl window that offers better energy efficiency.

Okna Windows vs Simonton

Eleanor - Homeowner - from 2016

Eleanor, I would get more bids and see what other installers have to say. The bids are free opinions and there is no right answer, it is completely dependent on your project particulars.

Okna Windows Warranty

I liked the Okna windows really well, but the Wingler Window company sales person is what shot them down. I did not like games and he was playing with the prices. He tells me I need all the windows in rooms with water with tempered glass, I know that drives the prices up. He gives me a $25,000 price. Leaves and takes the fliers with him, then calls me back in about 20 minutes with my price down to about $22,000 without tempered glass in the windows and a company discount included. Then I get a price later that day of over $28,000, no tempered glass.

Then a few days later I get a $1500 discount and I hope that helps your price. I do not know what I was getting! Those windows were 36" x 60" (the ones he missed). I am only adding grids has an option. The glass was supposed to be upgraded and these windows were their ones with wood veneer, so their top of the line windows.

Robin - Homeowner - from 2015

Additional Okna Window Review

Okna is a good company, they make some of the best windows available. For each .01 difference in u-value, you'll save about $100 a year in energy costs. The Oknas are more expensive than a lot of brands but you're going to satisfied in the long run.
