What is Renewal by Andersen® Whole Window Performance?

Windows perform several functions in your home; they protect your home from the weather, boost curb appeal, and even save energy. For a window to perform all these, all its components must be in top shape and work together smoothly. This is the basis for Renewal by Andersen® of Central Illinois whole window performance.

Sliding Windows

When we install your replacement windows in Bloomington, IL, we focus on making sure that they are durable, energy-efficient, and lovely to behold. Here’s what you need to know about how we get it done:

Heavy-duty Frames

Our windows feature our exclusive Fibrex® frames. This is an advanced composite that combines the strength and beauty of wood with the low maintenance of vinyl. It has a low expansion/contraction rate, which enables it to withstand harsh weather and temperature changes, with ease. As a result, your window frames will not rot, crack, pit, blister, or corrode for years to come. Fibrex also comes in a myriad of colors and patterns to suit just about any home design.

High Performance Energy-Efficient Glass

We offer three energy-efficient glass options, each with their own features and capabilities that can boost indoor comfort and reduce your energy costs:

● High-Performance™ Low-E4® glass – This glass option is 45% more energy-efficient in winter and 56% more in summer

● High-Performance™ Low-E4® SmartSun™ glass – More energy-efficient in winter and in summer by 45% and 70% respectively, and can also block up to 95% of UV rays

● High-Performance™ Low-E4® Sun glass – Features the highest rating against solar heat gain, which means you get to enjoy a cooler home even in warm weather

These options can cut your energy bills by up to 25%. Whether it’s a casement, picture, sliding, or bay window in Champaign, IL, you can be sure of greater energy savings.

Excellent Installation

We custom build each replacement window to match the exact specs of your home. This way, we are able to eliminate any issues with the fit during installation. We also make sure to seal any gaps between the frame and the window with caulking foam to keep it fully airtight.

Let Renewal by Andersen® of Central Illinois install your bay, sliding, picture, casement, and double hung windows in Galesburg, IL, today, so you can enjoy the benefits of our whole window performance. We back them all up with unbeatable warranties for your absolute peace of mind.

"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!"
