Andersen Windows’ High Performance™ Low-E4® Glass

At Renewal by Andersen® of Rapid City, the satisfaction of the homeowners we work with is our number one priority, and that’s why we install windows that have key features that can improve your home’s comfort levels and even energy efficiency.

In this post, we discuss one of the key features of our home replacement windows – its High Performance™ Low-E4® Glass. Learn how this top-of-the-line glazing benefits your home.

What is Low-E4 Glass?

Low-E4 glass is low-emissive, which means it has the uncanny ability to reflect heat during summer while keeping it in when the temperature drops in winter. This makes our glass perfect for homes located in areas with seasonal climates, with the window glazing essentially helping the home ‘breathe’ and stay energy-efficient during liminal periods.

How Energy-Efficient Is it?

Andersen’s High Performance Low-E4 Glass is 56% more energy-efficient in summer and 47% more energy-efficient in winter compared to ordinary dual pane glass. This higher energy efficiency translates to longer-lasting windows and even lower heating and cooling usage for your home!

We also offer special variants of our Low-E4 glass for homeowners looking for even more energy efficiency. Our High Performance Low-E4 SmartSun glass, for example, blocks 95% of harsh UV rays while also offering superior energy efficiency during summer and winter. We offer these as part of our casement window replacement services.

Glass and Frame Combo

We pair our superior glazing with our Fibrex® window frames. These are made from a composite of real wood fibers and high quality polymer, resulting in a composite window frame that boasts the beauty of natural wood with the low-maintenance properties of vinyl. Paired with our Low-E4 glass, your new windows from Andersen will be the most energy-efficient ones you’ll ever get!

Renewal by Andersen of Rapid City is ready to install your new energy-efficient windows. From awning windows installation to home window replacement, you can count on us to properly install your new investment so you can take full advantage of all its benefits.
