What is Low E Glass?

What is Low E Glass | Low Emissivity Glass | New Windows for America

Low Emissivity Glass, also known as Low E Glass, has a coating applied to it to make windows more energy efficient. Low E glass is one of the cornerstones of any energy-efficient window. Its primary purpose is managing radiation, whether it is solar, light ultraviolet, or heat. The secret is two microscopic layers of silver, which reflect heat back to its source. Other layers in the Low E coating filter ultraviolet and solar radiation, while allowing visible light through.

The Basics of Low E Glass

Low-E coatings keep the interior of homes cooler in the summer, and warmer in the winter by allowing visible light to pass through the glass while reflecting heat back to its source.

The Science of Low Emissivity Glass

Low Emissivity (Low E) glass manages radiation, including solar, light, ultraviolet, or heat via two microscopic layers of silver. The silver reflects heat back to its source.

How does Low E Glass work in different environments?

In predominantly heating environments, IntelliGlass reflects furnace heat back into the home, reducing the burden on the furnace, yet keeping your home warm and comfortable. Some solar radiation passes through the glass, acting as a source of free energy. Most UV radiation is blocked, while a high amount of visible light shines through.

In predominantly cooling environments, IntelliGlass reflects exterior heat away from your home. Solar radiation is filtered to preserve the comfortable indoor temperature the air conditioner provides. Most UV radiation is blocked, while a high amount of visible light shines through.

What about Gas Filling? Is it really in there?

Argon gas is an odorless, non-toxic gas that’s injected between panes of sealed glass to increase a window’s insulation and sound-proofing capabilities. Argon gas increases the R-value (measurement of thermal resistance) by minimizing the heat exchange through the window while reducing the possibility of condensation and frost build-up in cold or humid climates. Argon is an inert gas that is denser than air, making it more difficult for heat or cold to transmit through glass. Vinylmax uses sophisticated filling equipment and a Thermal Check verification system to ensure maximum performance.

What if our home is in a climate that is both heating and cooling?

Each IntelliGlass package features climate-specific Low E glass that is designed to maximize energy efficiency for your Energy Star Climate Zone. Choosing a triple-pane option provides the ultimate in window performance and meets Energy Star Most Efficient performance criteria.

Why Should I choose an Energy Star-qualified window?

You can improve your indoor comfort while saving money on heating and cooling costs. Replacing your home’s window with Energy Star-qualified windows can filter out damaging ultraviolet light, and save you hundreds of dollars on heating and cooling costs.
