Windows Q & A: How Do They Save Energy?

If you want to make the most of your window replacement, don’t just focus on the window style. You need to make sure that your replacement units can also add to your home’s energy efficiency. It might seem like an overwhelming process, given the number of options available today. Fortunately, you can turn to Renewal by Andersen® of Central Illinois to help you narrow down your choices.

In this Q & A, we’ll discuss the components that make up your energy-saving replacement windows in Springfield, IL.

1.) Which window framing material should I choose?

The right kind of material adds to your windows’ insulating properties. There are a variety of choices you can go for, including wood, vinyl, and aluminum. There are also composites that you might want to check out. This includes Fibrex®, the exclusive material Renewal by Andersen uses for sashes and frames.

This excellent composite combines the strength and insulating properties of wood with the low maintenance features of vinyl. Fibrex keeps an airtight seal that prevent significant loss. It also proves its durability with its low thermal expansion. This means it doesn’t expand or contract as much when exposed to extreme changes in weather or temperature.

2.) What exactly is Low-E Glass?

This refers to low-emissive glass, which comes with a special coating that cuts the transfer of UV and IR light from the outside. Renewal by Andersen windows, for instance, come with High-Performance™ Low-E4® glass. This advanced component helps your replacement windows in Decatur, IL, keep a more thermally comfortable home, minus the high energy costs. It helps protect your interiors from sun damage, as well.

3.) What are gas-filled windows?

Most replacement windows today have an inert gas in the space between the glass panes. This gas offers better insulation, further boosting the windows’ thermal efficiency. Renewal by Andersen of Central Illinois uses an argon gas blend for our replacement units. Two sealants, compressed butyl and silicone, hold this gas in place and prevent air leaks.

4.) What can you tell me about spacers?

These don’t just refer to the space between the glass panes, but also to the material that holds the glass firmly in the window. As your expert for windows in Springfield, IL, Renewal by Andersen uses low-conductivity, stainless steel spacers. They stop drafts from compromising your home’s thermal stability, helping keep costly energy inside your home.
