High Performance™ Low-E4® Glass

This glass type is perfect for homes in seasonal climates where both heating and cooling costs are a concern. High Performance™ Low-E4® glass is 56% more energy efficient in summer and 47% more energy efficient in winter as compared to ordinary dual pane glass1.

High-Performance™ Low-E4® SmartSun™ Glass

Our High-Performance™ Low-E4® SmarSun™ glass is the most energy-efficient glass option we have ever offered. It’s 70% more energy efficient in summer and 49% more energy efficient in winter as compared to ordinary dual pane glass1. Without tarnishing the view, Low-E4® SmartSun™ glass blocks 95% of harsh UV rays that not only heat up the room, but can damage drapes, artwork, and furniture. This glass option is unique in that it has the thermal control similar to tinted glass, but with the visible light transmittance of clear glass. What’s more, our Low-E4® SmartSun™ glass cuts down on noise pollution by reducing sound penetration into your home.

High Performance™ Low-E4® SmartSun™ Glass with HeatLock® Technology

Meeting today’s most stringent energy codes and requirements, HeatLock® Technology™ is our newest technology. By reflecting the escaping room-side radiant heat back into the room, Low-E4® SmartSun™ glass used in combination with our  HeatLock® Technology™ coating offers near triple-pane performance in a dual-pane glass. 

High-Performance™ Low-E4® Sun Glass

For hot, dry climates with little to no shade, our High Performance™ Low-E4® Sun glass helps reduce cooling costs by filtering out heat from the sun. By utilizing a subtle tint coating to reduce visible light, Low-E4® Sun glass has our highest rating against solar heat gain, helping to keep your home cooler.
