The Multiple Energy Efficient Parts Of Our Window Glass

Spectrally Selective Low-E Coating

On the inside and outside surfaces of our windows’ exterior glass, there are multiple spectrally selective low-emissivity (Low-E) coatings. Compared with typical double-pane windows, windows that have several Low-E coating layers reflect more solar heat and ultraviolet (UV) rays while maximizing the amount of visible light. In addition, during colder months, this special coating bounces indoor heat back inside to prevent unwanted heat loss.

Double Glazing

Our energy-efficient windows feature two panes of glass with some space in between. Our parent company, the Andersen® Corporation, has optimized the width of this air space to minimize thermal transfer. Research shows that a lack of space diminishes the double glazing benefit while too much space can increase heat loss.

Dual Seal

We use a dual seal system to keep the panes of our replacement windows secure. Our specially formulated silicone seal provides structural support while our compressed butyl seal acts as a gas barrier. The secret to our dual seals’ performance is our precise sealing process. We remove the Low-E coating around the embedded glass edge to provide our sealants a clean surface to stick to, making the seals strong.

Argon Gas Blend

Argon is one of the best insulating gases because unlike carbon dioxide and Freon, argon is not sensitive to seal failure and doesn’t discolor. To better improve window performance, we developed our own argon gas blend that helps improve our windows’ insulation capabilities. This gas blend also helps with soundproofing.

Stainless Steel Spacer

The spacer keeps the two panes stable, acts as a moisture barrier and preserves a gas-tight seal on our windows. Typical spacer materials, such as aluminum and plastic, conduct more energy and will deteriorate over time. We use stainless steel for our spacers because it is more stable and resists seal breakage. Since it is stronger than other spacer materials, we’re also able to use a thinner spacer wall that leads to better energy efficiency.

These features elevate our casement windows and other window types above the competition. Our energy-efficient glass packages can improve your home’s overall efficiency and help make your interior feel more comfortable. We serve many areas in Missouri, including St Charles.

"Very pleased with installation of six windows and a ProVia entry door. I love the look of the windows and door. I am pleased that my wife is thrilled with the look of the door. She is very pleased that the bronze color fits in well with the color of the brick."

"I just had my Renewal by Andersen windows installed and couldn’t be happier, the entire process went very smoothly. The windows are high quality and look great. But the installers Roy, Zack and Jordan were the stars, they introduced themselves upon arrival walked me thru everything they were going to do and when they finished took me to each window to make sure I was completely satisfied. They were clean and courteous and I would definitely recommend and have them work in my home again."

"Wonderful experience with knowledgeable, competent employees. We had Andersen windows in a previous house & didn’t even consider anything else this time. After replacing our patio door almost two years ago, we replaced all our windows this year. What a difference over builder-grade windows, especially in the really cold temperatures we’ve had this year. Andersen windows may be a little more expensive than other brands, but they are top quality."
