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 and Polaris. (But remember that many companies make 3 different levels of window, their economy, their mid range and their premium model.) 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 5 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, 700 Series which are 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 500 vs 800

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, serach 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.

Sunrise Windows vs Okna 500 Series

I received quotes for Sunrise and Okna 500 windows, Okna 500 being $300 cheaper. The salesperson told me that Sunrise uses Cardinal glass which is much better than Okna's glass. Is that the case? Also, which is better Sunrise or Okna 500, if I am considering replacing two double hung windows with one slider (76 x 48)?

Natalie - Homeowner - from 2015

[Site Editor's Response]

Natalie, I've never heard that the Sunrise glass is better than Okna. I don't actually know what type of glass Okna uses. I would say this - ask the salesperson to give you the U-factor, air infitration and Design Pressure numbers for the Sunrise and Okna 500 and see how they compare. The lower the U-factor and AI the better - with DP numbers, the higher the better (not as important, but I'm just curious). Make sure he is comaring apples to apples, the standard low-e glass with argon fills. Okna has some pretty awesome AI numbers. I've always been under the impression that the Okna would perform slightly better than the Sunrise. I would LOVE to hear what he says. Beyond this, both of these vinyl windows are excellent. I would say at this point that the installation quality would be more important than deciding between two very well performing vinyl windows.

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.

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 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 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.

Sunrise vs. Okna

The better lines of Okna and Sunrise are pretty comparable. Even their basic lines are better than maybe 80% of other brands out there, even some so-called premium ones.

Barry - Contractor - from 2012


Okna 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 400 Windows Reviews

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 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.

Steven - Homeowner - from 2009


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.

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.
