Our Energy-Efficient Glass Packages

When selecting your replacement windows, it’s best to choose energy-efficient units to help you make the most of your investment. A window’s energy efficiency is measured through a number of factors like the installation and framing material. Your choice of glass also affects your window’s energy efficiency. Renewal by Andersen® of Central Illinois offers high-quality window glass packages that provide superior efficiency. We discuss them here:

High-Performance™ Low-E4®

This is our standard glass option that comes with all our windows and doors. It can provide up to 45% more energy efficiency compared to the standard dual pane glass in winter. Meanwhile, it can offer up to 56% more energy efficiency than traditional glass options during the summer. Additionally, it also blocks up to 84% of harmful UV rays, helping protect your drapes, furniture, decor and floors from damage and fading.

High-Performance™ Low-E4® SmartSun™

For homeowners looking to significantly improve their home’s energy efficiency, we recommend our High-Performance Low-E4 SmartSun for your windows. As our most energy-efficient option, it has our highest energy efficiency rating in all weather conditions, helping you cut back on excessive energy use, leading to lower bills. Our SmartSun glass can also block up to 95% of UV rays, while still letting in a healthy amount of natural lighting.

Our two glass options can offer excellent energy efficiency for your home. Depending on the type of climate you live in, the architectural style of your home, and your window’s orientation to the sun, one of these may suit your needs better. Both glass packages are available for all our window and door options, so you can ensure that your home is both comfortable and energy-efficient even during extreme weather conditions.

"I would recommend RBA of Central Illinois for QUALITY windows and doors. Compared to our old cheap, thin vinyl windows, Andersen blows them away. You can easily tell by how well the sliding doors fit and close, and how heavy duty they are. We also cannot hear the wind rushing through the house in inclement weather anymore! And the black window frames we went with are amazing to look at. Aaron, Al, Darrell, and Cory all were professional and went all out to finish the job, given the weather they had to deal with. I would definitely recommend. They were also on top of communicating with me given the weather delays, and what I could expect for them coming out. Five stars!"
