Breathtaking views with no sacrifices

Expansive windows and sun-drenched rooms add beauty to any home—but they can also add heat and glare. ClimaGuard 55/27 coated residential glass is the energy-saving answer for waterfront and mountain-view homes, as well as homes in the West, Southwest and Gulf Coast. It blocks more solar heat than ordinary glass to keep interiors cooler, even on the hottest, sunniest days. It also minimizes glare without darkening rooms.

Key features:

Stunning views without the sacrifices: Allows light in but not glare or heat
Reduces air conditioning use: Blocks 73% of the sun’s heat
Comfortable all-season temperatures: Reduces trapped heat from expansive windows, particularly west- and south-facing
Can be laminated: For added protection against inclement weather
