Alpenglass™ powered by Heat Mirror®

 

Key product benefits

  • Alpenglass™ with Heat Mirror® IG provides center-of-glass U-value performance as low as 0.05
  • Different film types can be combined with different glass types in order to “solar-tune” a building and achieve the ultimate overall performance
  • Offers superior winter heating & summer cooling due to its super-insulating multi-cavity design
  • Blocks 99% of harmful UV rays
  • Maintains a warm glass surface temperature for maximum comfort and minimum condensation during winter
  • Weighs about 33% less than triple pane glass. Drop-in solution for framing systems designed for dual-pane glass
  • Improves STC by up to 4 dB over dual pane IG and can be used with laminated glass for maximum noise abatement
