What Low-E Glass Contributes to Your Windows

You shouldn’t have to decide between comfort and low energy bills. Having energy-efficient windows can lower the demand for indoor heating and lessen your home’s environmental impact.

What Low-E Glass Contributes to Your Windows

High-Performance™ Low-E4®

For homes in seasonal climates, it is important to utilize a low-E coated window such as our High-Performance Low-E4 glass that is up to 56% more energy-efficient in summer and up to 47% more energy-efficient in winter. From our picture windows to our specialty windows, our products come standard with this glass.

High-Performance Low-E4 SmartSun™

We have improved our products and now have the most energy-efficient option among all other dual pane options: the High-Performance Low-E4 SmartSun glass. With even higher energy efficiency and the SmartSun technology, this glass option is able to block up to 95% of UV rays that heat up a room. What’s more, it acts like tinted glass with its thermal control but provides nearly all of the visible light transmittance of clear glass. As an added bonus, it’s able to cut back on noise pollution by limiting the sound penetration in your home.

High-Performance Low-E4 SmartSun glass with HeatLock®

Best for very cold climates, our High-Performance Low-E4 SmartSun glass with HeatLock technology provides homeowners with nearly triple-pane performance in a dual pane glass. This newest technology reflects the escaping room-side radiant heat back to the room, reducing energy costs.

High-Performance Low-E4 Sun glass

High-Performance Low-E4 Sun glass is the best choice for hot and dry climates. It saves on cooling costs by filtering out heat from the sun with a subtle tint coating to reduce visible light, helping your home stay cool even on the hottest days.
