Low-E Glass Benefits for Northern Virginia Summer Heat

Why Northern Virginia Summers Put Windows To The Test

Homes with older windows often see the same pattern, a room heats up fast, the AC runs longer, and the glass itself seems to radiate warmth back into the space.

That is where Low-E glass earns its keep. It is designed to reduce the amount of solar heat that passes through the window while still letting in useful daylight.

How Low-E Glass Works In Real Homes

Low-E means low emissivity, which is a way of saying the glass is made to reflect heat rather than absorb and re-radiate it into the house.

During summer, sunlight carries a lot of heat energy. Low-E glass reduces how much of that solar gain gets inside, and it also cuts the amount of heat that radiates through the pane.

Not every Low-E coating behaves the same way. Some versions are aimed at stronger summer solar control, while others are selected for a balance of winter and summer performance.
