SmartSun Glass

In 2008, Renewal by Andersen® introduced an exciting new development in glass technology. High-Performance™ Low-E4® SmartSun™ glass is now the most efficient glass option available for Renewal by Andersen windows. It builds on the best features of dual-pane glass to even more effectively reduce home heating and cooling bills while still standing the test of time.

SmartSun: More than Just Glass

With increased concern for the environment and the rising cost of fuel, making homes more energy-efficient has become a prime consideration for both building material manufacturers and homeowners. SmartSun reflects Renewal by Andersen’s ongoing commitment to energy efficiency and environmental protection. Innovative SmartSun glass gives you the ability to save on utility costs because it blocks the sun’s heat while still allowing natural daylight to pass. Consider these benefits.

– When compared to ordinary dual-pane glass, SmartSun glass is up to 45% more efficient in winter and 70% more efficient in summer. Depending on your location, this can result in energy savings of up to 25% over time.

– SmartSun glass stops 95% of all UV rays, the light spectrum which causes damage to furniture and fades carpet, draperies, wall coverings and artwork.

– An innovative coating stops water spots and makes cleaning less troublesome.

– SmartSun glass significantly reduces noise pollution entering your home.
