SunGuard IS 20
Boost performance to meet U-value requirements
It can be a challenge to minimize heat loss in cold climates, and cooling loss in warm regions. Enter SunGuard® IS 20 coated glass. This interior-surface solution helps buildings meet strict energy code requirements by improving U-value performance in double-glaze and triple-glaze units.
Key Features:
Neutral color: Features a low haze and an ultra-smooth surface
High light transmission: Allows for more visible light indoors
Easy maintenance: Able to be cleaned with common glass cleaners
Greater energy savings: Helps projects qualify for LEED® credits
