What does LowE glass do?
In the wintertime, the suns energy is “short wave radiation” that passes through the window and is absorbed by carpet and furniture, etc. Then the energy is transformed into long wave radiation. The long wave radiation wants to flow from warm to cool, naturally it will try to escape from glass. At night time, the radiant heat produced from furnaces, wood stoves, etc. will also want to escape out. The LowE coating prevents this when the radiant room side heat is reflected back into the home which results in lower winter u-values. In the summertime, the LowE coating “manages the suns heat” by reducing the amount of heat transferring through the window. The LowE coating filters the suns short wave radiation which cuts down the amount of solar heat gain into your home. Throughout the year, LowE reduces ultraviolet rays, which can damage curtains, flooring, furniture, etc. It also reduces heating and cooling costs for both cold and warm climates. LowE glass differs in color and each manufac
