SMART GLASS

Warmer in Winter
Low E2 Glass and Argon add comfort to your home. Energy from the sun is transmitted through the glass to the interior of your home where it is absorbed by carpeting, walls, furniture etc. This becomes long wave infrared radiation. Heat energy from lights heating registers, fireplaces etc. also are long wave infrared radiation. When this long wave energy rises to escape through the glass, Smartglass 4.17 reflects 96% of this energy back into the room with a resultant higher winter R Value.

The Low E2 coating reflects much of the direct sun's rays and virtually all of the long wave radiation from materials outside the home such as pavement, sidewalks, earth etc. Approximately 60% of short wave radiation is reflected while about 96% of long wave radiation is reflected. No glass available today will totally eliminate fading, however, with Smartglass 4.17 and its ability to eliminate approximately 86% of the ultraviolet rays, you will dramatically prolong the life of the material within your home.
