High Performance™ Low-E4® SmartSun™ Glass

Compared to standard dual-pane glass, our SmartSun™ glass is 45% more energy efficient in winter and 70% more efficient in summer; it’s a great performer here in the Raleigh-Greensboro-Fayetteville area. And that’s just the start. Here are some other benefits delivered by SmartSun™ glass:

UV Protection

SmartSun™ glass blocks 95% of harmful UV rays from passing through your specialty window; it’s wonderfully effective at protecting your furniture, artwork, drapes, and carpet – including Oriental rugs – from fading.

Increased Thermal Protection

SmartSun™ glass seals our specialty window panes against the entry of outside air. In addition, the panes are separated with a patented low conductivity spacer and filled with a blend of argon gas to further reduce thermal transfer. Together these features can reduce your energy bills by up to 25%*.

*A study comparing Low-E4® SmartSun™ glass to ordinary dual pane glass revealed a 25% savings on cooling bills and 10% savings on heating in identical homes. Savings may vary.

Reduces Sound Penetration

Compared to single and double pane glass offered by other manufacturers, SmartSun™ glass significantly reduces sound penetration, insulating you and your family from unwanted noise.

Easier to Clean

Sunlight loosens any dirt that adheres to our innovative glass coating; this allows natural rain water to wash the dirt away. The coating also enables the glass to dry more quickly while almost completely eliminating water spots.
