Low-E4® SmartSun™ Glass: Features and Benefits

Renewal by Andersen® of Austin offers customizable windows and doors that deliver excellent energy efficiency and reliable long-term performance. This is in large part thanks to our advanced Fibrex® framing material and our plethora of exclusive glass options, including our High-Performance™ Low-E4® SmartSun™ glass.

About SmartSun Glass

One of the most energy-efficient glass options available today, our SmartSun glass builds on the vital features of double-pane glass to reduce your home’s energy consumption. Thanks to its advanced coating technology, it is 70% more energy-efficient during summer and 49% more energy-efficient during winter than regular glass.

Exceptional UV Protection

Similar to low-emissivity glass with spectrally selective coatings, SmartSun glass admits abundant natural light into your home while blocking unwanted infrared and UV rays, which are responsible for heat and furniture fading, respectively. With SmartSun glass, you can enjoy refreshing daylight in your home without worrying about your living space heating up from the sun or your furnishings fading due to UV exposure.

A Worthwhile Investment

Whether you want to install custom windows or replace your worn-out patio doors, choosing SmartSun glass provides more benefits than any standard dual-pane glass can offer. SmartSun glass helps naturally cool your home on hot summer days and helps keep your living space warm on cold winter days. In doing so, it reduces your reliance on your HVAC system, which leads to lower energy bills.
