It’s not unusual for some windows to have a green tint to the glass, with homeowners asking what it is after installation. Is there something wrong with the glass? Is there a film or covering on the window? To discover why we contacted several manufacturers.
Why do new windows have a green tint? New windows have a green tint because they have been manufactured with silicates that contain an elevated level of iron oxide. This is to protect the glass from scratching and breaking. Glass with a low level of iron, have less of a green tint and are more expensive to manufacture.
A lot of people think that new windows are green because of the manufacturing process but this is not true at all! In this post, we will help you learn everything about windows with a green tint. So, let’s dive in!
Why do my house windows have a green tint
It’s a low-e (low emission) glass, which is a more energy-efficient upgrade that aids windows in retaining cool air inside and summer heat outside where it belongs.
When looking at the light of transparent glass, you may notice a slight green tint to it, which becomes more apparent when viewed from an angle and gets even darker as the thickness increases.
This physical property is known ambiguously as standard clear glass, clear float glass, conventional clear glass. This color derives from the iron oxide content within the glass. “The low-e material is naturally green in its natural state,” claimed Anlin Windows & Doors.
Iron is used in the production of glass tabletops and table coverings, giving them a greenish tint. This is typical of all glass tabletops and table covers in the industry, and they’re called transparent glass. When viewing the glass piece from the four edges, this greenish tint is most obvious.
If this is something you wish to avoid, low-iron glass is an excellent alternative. Low-iron glass has the same characteristics as transparent glass, but because there is less iron in it, it has a clearer appearance and fewer greenish tinges.
The color of glass produced from silicates (sand) with the conventional iron oxide content will be green, and the thicker the piece of glass, the more obvious it is. The glass looks very green when viewed from the side. As a result of increasing demand, iron glass is more common in Europe.
Here is a video explaining what low-e windows are:
Windows with a green tint have a lot of benefits. Here are a few of them:
Windows with low e glass, which are greenish, such as Low-E double-pane windows, will save you money on your HVAC system by keeping heat energy loss to a minimum in the winter and gaining in the summer. They also help to keep your property pleasant throughout the year. I recommend checking out Transom’s Low-e windows on Amazon by clicking here.
Low-e windows are ideal for use in harsh weather and on outside walls that are exposed to intense sunshine or strong winds.
According to the U.S Department of Energy, The heat gain and loss through windows are responsible for around 25%–30% of home heating and cooling energy usage.
They also protect the interior décor from fading by filtering UV light. For a longer period, your wall paint, furniture, artwork, curtains, and carpets will all look great. I recommend browsing Gila’s low-e window film on Amazon by clicking here.
What type of glass has a green tint?
A glass that has a prominent level of iron, will have a green tint. There is another reason for the green tint, especially in windows that are exposed to the weather. The glass in these windows could be low-E glass.
Low-E glass has a green tint. The term “low e” refers to a low level of heat loss. Low e-windows are made of treated glass with ultra-thin layers of metal or metallic oxide applied to them. Outgoing infrared radiation (also known as “heat energy”) is reflected, lowering heat loss by 30-50 percent.
Though you may believe the transparent glass is the most transparent, this isn’t correct. Although clear glass is low in iron, it has more than high-iron glass.

Pella Windows, a private door and windows manufacturer, mentioned that some of their glasses have a little tint, but it’s due to the silver oxide layer. They also provide bronze, gray, and green-tinted glass in many of their products, but it’s only for aesthetic purposes and can reduce the energy efficiency of the glass.
The higher levels of iron produce a greenish hue, which becomes more apparent as the glass grows thicker. This is due to the natural presence of iron oxide from minerals such as sand or from the cask or container where the glass was melted.
Despite its intuitive nature, this may sometimes result in failures in specific applications.
The low iron in a window may be detected by doing the following:
- Holding a match flame or a pen light to the window from the outside.
- In case the window contains low-e glass, one of the pictures will be a different color than the other images.
Is all Low-E glass green?
The majority of individuals are unaware of the color difference. Low-e materials are somewhat reflective and have a slight green tinge to them.
The inside surface of insulated-glass panels is coated with a thin metallic layer to great effect. The glass might have a bluish or even light green tinge to it. This coloration is only seen in Low-E glass that does not contain a metallic coating.
Is Low E glass also tinted?
Low-E isn’t tinted glass initially. Tinting is achieved by adding alloying ingredients to the raw material itself.
Low-E windows are treated with a microscopic reflective metallic coating during production, which reduces the amount of ultraviolet and infrared radiation that can pass through glass.
The problem is that the glass’s color (green, gray, or bronze) comes from the reflective coating, so they can’t match the transparent windows.
The ordinary Low-E glass is known as “clear” on the outside of the building, yet appears green when seen from the outside. The color stands out against a backdrop, such as blinds or shades.
Low-E coatings are distinct; they should not be used together with window tinting because slight discoloration is possible. As the depth of color on the glass changes depending on the thickness of the glass, alloy materials are added to it.
A Low-E coating, on the other hand, is a thin metallic layer that is applied to the glass and does not show color variations based on the thickness of the glass. It may have a minor, usually unnoticeable, reflective tint and a tiny amount of green tinge.
Hence, not all the Low-E glass is green. Ideally, Low-E coatings should be clear.
Low-E coatings of various colors such as bronze and green are available depending on the needs of customers for its application in houses and buildings that require energy conservation design criteria.
Problems with low-e glass windows
Low-e glass windows are susceptible to several issues, one of which is their highly reflective nature. There are additional discoveries that will be made about this sort of glass and will be shared with you so that you can avoid some of the problems many people have encountered as low-e window owners.
The most frequent issues that individuals have with low e glass are:
- When viewed in bright light or against a dark backdrop, the sky will appear gray. It’s not as obvious until it’s in the proper position. Then it’s difficult to overlook. It can make a home seem strange if there are any low-e glass windows alongside traditional single-pane windows.
- Because the glass reflects more color, it isn’t necessarily transparent in appearance and causes people to believe it is unclean when it isn’t. Many people despise cleaning windows, especially when they aren’t really filthy.
It’s a small price to pay to make your property seem visually appealing to passers-by. If you despise washing grimy windows, you’ll despise washing windows that appear dirty but aren’t even dirtier.
- It warps siding. It damages siding because it causes it to bend. For me, maintaining the appearance of my home is a top priority. Siding isn’t something that can be replaced easily. In certain cases, low-e windows’ reflecting light has been known to concentrate on areas of siding and heat them up to the point they melt.
- It kills plants because they can’t keep their roots wet enough to live. I enjoy gardening, and I’m well aware that plants require a lot of light.
Still, there is such a thing as going too far. If your garden isn’t placed in a shadier sector of the yard, you can expect to have an abandoned garden that doesn’t grow effectively owing to its extreme dryness.
Are there colors options for a Low-E Glass Coating
The colors on walls, textiles, and artwork are wonderful. Is there a place for them on your windows? For decades, there have been significant improvements in the field of technology to provide homeowners with more efficient and higher-performing goods and systems. Your glass windows and doors are but one example of these advancements.
Your house’s most significant investment, your windows, and doors, can now be found in a wide range of styles and colors. You may upgrade them with new glass or different kinds of window coverings to make them more stylish or create a unique aesthetic for your home.
But the bottom line is that you must pay attention to how you wash them. That way, when it comes time for replacement, they’ll match up nicely! -> Your windows and doors have evolved from impact glass to window coverings, becoming essential elements that help you save money long term on your largest and most important investment—your home!
There are several treatments and design choices for improving our Florida Approved impact installations, including Low-E glass coatings that help control energy bills and improve the performance of windows.
It’s worth noting that Low-E coatings are not the same, and they should not be used together with window tints. Because a Low-E coating may cause minor discoloration, it is critical to note that they are not the same. The depth of color will vary depending on how thick the glass is tinted.
A Low-E coating, on the other hand, is a thin metallic layer that is applied to the glass and does not have color variations based on the thickness of the glass. It may, however, have a minor, sometimes unnoticeable, reflective tint with a somewhat green hue.
Low-E glass coatings block out a larger range of light without reducing natural lighting, or visible light. What this means for you is more consistent illumination and lower energy bills, as well as the preservation of your interior materials such as curtains, furniture, and flooring.
Finding the Right Glass to Eliminate the Green
Clear glass is extremely common and is popular in a variety of architectural design applications. Also, it is compatible with controls for solar, it is not costly, and it is perfect when searching for color that is neutral.
Clear glass is not completely clear, if you were to place a piece of white paper under it, you will see that it has a green tint
In contrast, glass that is low in iron gets rid of the case of green that happens with clear glass. It is great for special design projects that require super clear glass, such as a coffee table that allows visitors to see the actual color of the wood flooring through the table.
Low-iron glass is often used:
- When it comes to connecting rooms, clarity and connectivity are critical.
- Where views from the top-down are essential.
- Balustrades, dividing walls, and showcase cabinets are all examples of interior features where low-iron glass is used more often
Starphire® glass is not always required. However, not every project budget or application necessitates a low-iron glass with Starphire® glass’s unique features. Acuity™ Low-Iron Glass, for example, is an affordable low-iron alternative that has high apparent light transmittance (VLT), even when money isn’t available for a premium product like Starphire® glass.
