Works of Low E Glass

In the winter, Low-E Glass is designed to work in two ways:

First-----it transmits the sun's short-wave energy. This means it allows the sun's energy (which provides visible light and invisible heat) in through the windows, which helps heat a home in winter.

Second-----once the sun's heat is inside a home, the coating works to reduce the amount of heat transferred through the glass to the colder exterior.

Third-----less of this heat, as well as the heat produced by a furnace, is transmitted back through the glass to the outside, helping to reduce heating bills in winter.

In the summer, heat enters a house through ordinary clear glass to the cooler interior. This happens in two ways:

First-----through direct short-wave sunlight; and second, by long-wave radiation generated by sidewalks,driveways, and other elements which have absorbed heat from the sun.

Second-----Low-E Glass effectively reduces this unwanted radiant heat gain by reflecting a significant portion of long-wave radiation back to the outside, helping to keep homes cooler and reduce cooling costs in summer.
