We Answer Your FAQs About Replacement Windows

As a homeowner, you probably have several questions about investing in new windows for your home. As with any home hardware, there are plenty of variables, especially if this is your first time replacing your windows.

Replacement Windows

At Renewal by Andersen® of Central Illinois, we answer your frequently asked questions about your replacement windows.

Q: What’s a Replacement Window and Why Do I Need One?

A:  A replacement window is window custom-built to fit the opening of your old window without disturbing both the interior and exterior areas around it. The actual benefit of getting replacement windows is two-fold. Apart from ensuring that your frontage remains aesthetically pleasing, getting replacement windows ensures that your home remains as energy-efficient as possible. Additionally, replacement windows help your home maintain comfort levels throughout the year.

Q: What Is Low-E Glass and Why Is It Important?

A: Low-emissivity glass has a microscopically-thin metal or metallic oxide layer on the surface of the glass pane itself. This coating reduces the amount of infrared radiation the glass absorbs and passes through, ensuring a cooler glass pane. All our replacement windows use our High-Performance™ Low-E4® package that is 70% more energy-efficient during summer and 49% more energy-efficient during winter. Low-E glass also reduces UV light intrusion by 95%, ensuring comfort all year-round.

Q: What Warranties Come With Your Windows

A: When we install replacement windows in your home, we also back your new home hardware investment with Renewal by Andersen’s industry-leading warranties. This includes a 20-year limited warranty for the Fibrex® window frame and glass, a 20-year limited warranty on installation, and a 10-year warranty for the rest of the parts.

"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!"
