Low-E Glass Technology
Low-E Glass is coated with a virtually invisible layer of silver that reflects radiant solar energy while permitting visible light to pass through the glass.
In cold, winter climates, the Low-E Glass keeps rooms warmer by reflecting heat back into the home while letting warm, solar rays in. In hot, summer temperatures, the Low-E Glass lets visible light pass while reducing the infrared and ultraviolet radiant solar energy that enters. So your rooms stay cooler and you save on precious energy costs.
As an added bonus, because Low-E Glass blocks radiant solar energy, room furnishings will be better protected from fading or discoloration.
