Low-E Glass Costs
Low-e glass (low emission) is a very popular choice when it comes to replacement windows. This glass includes a thin layer of metal on one side - the metal is oxidized, which adds insulation properties to the glass. While the glass allows light and heat into the room, the sheen stops it from leaking back out again. This results in a more energy efficient window that can reduce the amount of sunlight that enters (low-e 2 lets in less light than low-e and low-e 3 lets in the least amount of light). The thin layer remains transparent, you cannot see the film. There are two ways the oxidized metal is added to the glass; either they add it as soon as it is removed from the tin bath or they apply it afterwards using a method called cathode sputtering.

Types Of Low-E Glass
Low-glass is available in a number of different varieties; the best one for your home is determined by both the climate in which you live and your project requirements. Here are the four main types.
Any Climate and Season Glass
This option maximizes temperatures set by you by air conditioning or heating within the home. This glass allows light to flow into the home, but reduces the risk of extreme heat escaping or entering the property.
Solar Control Glass
This option is designed for maximum insulation against the sun's harmful rays. This glass also assists in keeping the area cool when using air conditioning. The glass isn't tinted and looks like normal glass.
Glare Control Glass
This option has some tinting, but not too much. It absorbs the suns light, enabling a gentle glow to enter the property. You often find this glass is warmer to touch, but is not at all dangerous.
Winter Climate Glass
This option is a protective glass against the colder air. This glass allows for sunlight and warm air to enter the property, but stops the warm air from escaping.

Renewal By Andersen Window Glass Options
| Window Series | Total Quote Installed | Average Installed Cost |

"I received 4 quotes for 2 fiberglass replacement windows approximately 60 x60 each. They face the ocean side and the house was built in 1947. The quotes I received range widely.
First from a person who does installation but no license $5000 for everything including moulding around my window (Milgard fiberglass) seems like it was a full window and not a replacement.
Second from local milgard installer at $9,000 for full Milgard fiberglass window but said I needed contractor to take off the siding since he felt the wood was soft ( not true since I checked the surrounding wood and there are no leaks except for the windows themselves.
The Renewal By Andersen window cost is just...wow. Seems like the sales person knew what he was talking about when he looked at the windows when I noted that the old windows had a vertical frame (casements) that integrated into the house frame (the surrounding frame will not be replaced since integral with walls [ laster lathe walls). Said it would be covered and not show the notch where the vertical piece would be taken out but he forgot about the top of the window that is the same. Price came in at $13,500 minus potential discount making it around $11000.
Fourth was local dealer quote of $2700 (big difference) but he never took into account of the frame issue just said I could sand the frame and was a bit late getting back to me with the quote. All windows are for sliding fiberglass windows and are Milgard with the exception of the RBA that is the composite material. I wanted the best window glass rated rate sun and heat protection since this is a south west window and these old houses do not have any insulation.
I have had bad experiences with contractors before even when I thought I had good specifications, etc. I am relatively old (76) and have legal custody of 3 grandchildren so the funds are tight but I do not want major problems in the future like I have had with my siding and roof replacement that I can’t afford to fix.
In other words I need help given the vastly different quotes. I do want something that will be problem free and am willing to pay a fair price for a good product. Are the RBA so much better? I read on your site that the Marvin fiberglass windows seems good. I really need some help since the yelp reviews on these companies seem OK. Thank you very much for your help."

Editor's Advice:
Joyce, in terms of the windows themselves, Milgard makes a good fiberglass series. RBA makes a good composite as well, but they are almost always quite a bit higher and not worth the price they charge.
The big issue with your project seems to be the additional work involved, i.e. removing the siding (and window) and then checking to make sure the existing frame and sill don't have any water damage that needs to be repaired before the new window can be put in.
When you remove the siding, you could use either a new construction window (which includes a nailing fin or flange around the top and side) or a replacement window. The new construction route might be the way to go as it provides a good fit and better protection from water.
Here's my problem...it's virtually impossible for me to say who of the group is going to do the best job. If you are price conscious, RBA isn't the way to go, you are paying for the advertising and marketing etc.
I think you need to find an installer (either one of the ones you have or a new one) who has a good reputation for solid and thorough work. It sounds like $4 to $5K is the right price for the work.
But you definitely want to make sure that you go with someone who isn't going to throw in the windows and gloss over any of the frame work that may need to be done. I think you need to find someone with a track record you can trust,
either by using someone who firends and family has used or someone with some verifiable reviews.
Marvin fiberglass windows are also quite good, probably a step up from the Milgard. Their Infinity is the preferable to their Integrity model.

Anlin ZoE shield Extreme Glass
We live in the Phoenix metro area. We are looking to replace our 23 year old aluminum windows with a vinyl Anlin brand with ZoE shield extreme glass. What do you think? What is a fair price for 47” x 58” Thank You!

Maryanne, there are roughly 20 factors that can affect the per window price for a project. For a normal sized window like you mention with normal installation, I'd say you are looking at $550 to $725.

Clear Or Float Glass
Clear glass is less expensive and allows in more light - however it allows allows in more heat and is therefore less energy efficient. Float or clear glass is a lower grade glass than the low-e glass - although it typically allows more light in due to the absence of any tinting film. Float glass uses a process that creates flat, clear and smooth glass. The glass is poured into a molten tin tank (in a 100% nitrogen atmosphere). Glass is denser than the tin and therefore it floats to the top, creating a glossy and smooth surface with an even thickness. This is also a more economical way of creating this type of glass.
Once the glass has been placed in the tin tank, it is cooled at a slow rate before being put on rollers to cool. Rushing this process could lead to imperfections and cracks. The 100% nitrogen atmosphere is essential in ensuring the glass doesn't oxidize. Some of the tin is absorbed, but this can only be seen if you put an ultraviolet light against the sheet of glass.
Before float glass, the process of making flat glass was quite a detailed process which was done by blowing a crown or bottled shaped piece of glass. They would then cut the glass as flat as possible before it had time to harden. Using a machine that looks like a potter's wheel, they would spin the glass before cutting a window and allowing it to harden. The problem with this method is the number of imperfections you could see in the glass.
Consumer Window Glass Questions
Question on Bronze or Black Frames
Thank you I really appreciate it. I really want black/bronze windows but I am told they cost hundreds more per window. Do you think it’s worth it and do you think they will be standard one day? I have to decide my pool cage color based on windows if I want it to match lol
Thx!
Mylène - Homeowner - from 2022

Mylène, I sort of doubt those darker colors will be standard anytime soon because the companies are worried about the extra heat that those colors generate (long term warping issues), and about color fading over time. They open themselves up to all sorts of warranty claims -- that's my take, but I'm not sure it that's correct. I know it's a huge consumer trend though -- I think it's worth the cost if every time you look at your home you love the darker color. I just wouldn't do it if I lived in a super hot climate.

How Much Do Triple Pane Windows Reduce Noise
In terms of noise reduction, how much of a difference does triple pane windows versus double pane windows really make?
I live at the beach, not far from the boardwalk. Crowds on the boardwalk can be rather loud. But I am also concerned about visibility. Will triple pane obscure the oceanview?
I'm thinking about Okna and Joyce windows. Also have supply-chain issues affected window prices? If so, how much?
Ellen - Homeowner - from 2021
[Site Editor's Answer]
Ellen, high quality triple pane windows such as Okna or Joyce will do a ton to reduce down those exterior noises. You can order them with differing thicknesses which also helps to tune out different frequencies…or with tempered glass.
Triple pane should not affect the ocean view. Maybe by a tiny bit, but I’ve never noticed the difference myself. Double check with the Zen dealer (I’m assuming Zen Windows based on the two brands you mentioned…), but I’ve never heard of a consumer complain about this…
COVID, demand and supply chain has DEFINITELY affected prices. I might have to say 30% on average, but it’s really all over the board for the individual consumer. I’ve seen normal prices and crazy expensive pricing.
