Taking a Closer Look at Low-E Glass

In the home improvement industry, innovation is power. Companies that want to stay at the top of the industry, particularly those that manufacture windows, must continuously work on developing products that help make the everyday lives of homeowners and business owners more comfortable. One advancement that has greatly improved window performance is the development of low-E glass, which provides many excellent benefits.

The Benefits of Low-E Glass

Low-emissivity (low-E) glass has a very thin layer of metallic oxide applied to it. The function of this coating is to filter the ultraviolet light that passes through your windows, reflecting heat back into your home while still allowing natural light to pass through. During the cold winter months, low-E glass prevents heat from escaping through your windowpanes, while in the summer, it stops heat from entering your home. As it blocks UV and infrared rays, low-E glass does the following:

  • Lowers heating and cooling costs.
  • Helps prevent fabrics, furniture and artwork from fading.
  • Brings about an overall increase in the comfort of your home environment.

Low-E Glass Options

There are several different types of low-E glass on the market today, which allow for low, medium and high solar heat gain. The glass option you choose should be dependent on your climate zone and your home’s heating and cooling needs. Here at Renewal by Andersen of Northeast PA, the low-E technology in all of our available glass packages results in excellent energy savings. Our High-Performance™ Low-E4® glass, for example, is 56% more energy-efficient in summer and 45% more energy-efficient in winter compared with ordinary dual-pane glass.

"Our installation team, Josh and Mike, did a phenomenal job with the installation, cleanup, and "orientation" after the work was completed! We were totally satisfied with everyone that we dealt with before and after the installation...and would surely recommend Renewal by Andersen to anyone contemplating a window replacement project!"
