Consumers are becoming more educated about environmental matters. A 2016 Pew Research Center survey among American adults showed that 75 percent are particularly concerned about helping the environment as they go about their daily lives. And when it comes to the home, that concern is reflected in the products homeowners select. They are increasingly searching for products that will help them lower utility costs while reducing their carbon footprint.

Committed to Energy Efficiency
The right windows make a substantial difference in a home’s energy efficiency. According to, using ENERGY STAR®-certified windows can help homeowners reduce energy bills – and carbon footprints – by an average of 12 percent nationwide. Andersen Corporation has been an ENERGY STAR partner since the program’s inception in 1998, and in 2018, was presented with the ENERGY STAR Partner of the Year-Sustained Excellence Award by the U.S. Environmental Protection Agency and the U.S. Department of Energy. The award recognizes Andersen’s initiative in protecting the environment through superior energy efficiency.

At Renewal by Andersen of St. Louis, we share this commitment to being responsible stewards of our environment. We install products from Renewal by Andersen®, the replacement window division of Andersen Corporation, which produces a wide variety of replacement windows and patio doors that meet or exceed ENERGY STAR performance standards. Advanced technology in manufacturing has led to superior glass and framing materials that, when combined with professional installation, give homeowners optimal energy efficiency and beautiful windows that will last for decades.

Save Energy, Increase Comfort
Andersen’s latest development is SmartSun™ Glass with HeatLock® Technology, the most energy-efficient glass we have ever offered. This new glass option provides near triple-pane performance in a dual-pane window. SmartSun Glass gives you the benefits of Low-E glass, plus it keeps your home more comfortable by regulating the temperature while still letting sunlight shine through. The HeatLock coating reflects heat that likes to escape your home in winter, while also reflecting exterior heat that makes your home hot in summer. HeatLock coating was specifically designed to meet the more stringent ENERGY STAR® requirements for windows in the Northern Zone.

Stop Interior Fading
In addition to energy savings, another benefit of SmartSun Glass with HeatLock Technology is that it filters out 95 percent of harmful ultraviolet rays. Ultraviolet rays are a leading cause of interior fading. SmartSun Glass helps protect your furnishings from the damaging glare of the sun, so your furniture, curtains, carpets and artwork stay beautiful for years to come.
