How It Works







Enjoy the benefits of a Low emissivity window at a fraction of the cost of replacing your windows. (Low E) - actually low thermal emissivity - is a quality of a surface that radiates, or emits, low levels of radiant thermal (heat) energy. All Materials absorb, reflect and emit radiant energy. Emissivity is the value given to materials based on the ratio of heat emitted compared to a blackbody, on a scale of 0 to 1. A blackbody would have an emissivity of 1 and a perfect reflector would have a value of 0. Therefore, the lower the E value, the better the performance. (See What is Low-E)
The Emissivity of Thinsulate CC75 is .14!

The U-Factor is used by the National Fenestration Rating Council and measures how well a product works at preventing heat from escaping a building. U-Factor ratings generally fall between .15 and 1.2 and the lower the U-Factor the better a product is at keeping heat inside a building.
The U-Factor of Thinsulate is .62 on single pane glass and .34 on double pane windows.
