Can the right glass really reduce furniture and carpet fading?
Definitely. Ultraviolet rays are one of the best known causes of fading. Certain types of window glass can reduce the amount of UV Rays that pass through the glass. For example, soft coat Low E glass with argon blocks 64% of UV rays—a 42% reduction compared to clear window glass. But research has shown that factors beyond Ultraviolet light contribute to fading and damage. So the usual tests for UV transmission may not give you the whole picture. (Besides, UV rays are not all bad, plants need a certain amount of UV light to thrive.) A more accurate estimate of fading protection is called the Krochmann Damage Function. This method expressed in percentages, measures the amount of all damaging radiation (ultraviolet, infared, visible light, and heat) transmitted through window glass. The added Argon and Krypton gas transmits as little as 16% of UV rays and has a Krochmann function of 20%. Conversely, tested Pyrolitic Low E products showed a transmissions as high as 47% with Krochmann perce
