Ordinary dual-pane glass lets 62% of UV light pass through. Our High-Performance™ Low-E glass cuts that down to 17% with virtually no effect on the clarity and color of the light.
With Low-E glass, if your thermostat is set at 70°, the temperature of the innermost glass pane won't drop below 57° even if it's 0° outside. In warm climates, Low-E glass works just as hard to keep your home cool. For extreme climates, we also offer High-Performance Sun™ glass for maximum UV protection and temperature control.
