A new option for lower u-factor requirements.
In the U.S. and Canada, current and projected Energy Codes, as well as high-performance “Green” building codes, are pushing for lower u-factor requirements. SunGuard IS 20 from Guardian helps architects meet these codes by bringing the
u-value performance of double-glaze units closer to that of triple-glaze, and by
improving triple-glaze performance in buildings and climates where maximum
heat flow resistance is desired.
An interior-surface coating for significant energy savings.
SunGuard IS 20 is designed to be used on the #4 surface of a double-glazed unit, or on the #6 surface of a triple-glazed unit. As documented in the performance chart below, SunGuard IS 20 delivers lower u-values, less solar heat gain, and significant energy savings when combined with other low-E SunGuard coatings in IG units.*
Smoother and clearer than pyrolytics.
SunGuard IS 20 holds several distinct advantages over pyrolytic hard coats as well. Unlike pyrolytics, which have a rough surface, SunGuard IS 20 is smooth to the touch and easy to clean. What’s more, SunGuard IS 20 lacks the visible haze of hard coats, delivering a high visible light transmission.
