How Low-E Glass Works In Real Homes

The coating on Low-E glass is thin, but it changes how the window handles heat in a noticeable way.

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.
