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.

"This was one of the best experiences I've ever had with a company. I ordered the windows in November and was told they wouldn't be here until July. That kind of delay the new norm so I wasn't a bit upset with the timeline. I was given an early present when they called to say the windows would be in at the beginning of May. We agreed on the week of May 16th to do the installation, there were 30 windows and a sliding door to install. They arrived promptly on their scheduled install date, and got straight to work. By the end of day one, they had all the upstairs windows complete and their work was incredible. Day two came with more of the same, the crew showed up promptly, got straight to work, and when they left they had every window downstairs installed. The third day they again arrived on-time, and got to work installing the door. The door and windows are perfectly installed. The two lads that did the installation did a phenomenal job, and were friendly to boot. I would give them more business if I had any :) The service I received from the company was great. They kept me abreast of anything that was going on with my order. I appreciate my concierge, Christina, she was good at communicating timelines and getting everything scheduled."

"The two installers were great! They were polite and hard working and they cleaned up all the outside and inside. It was like they were never here. As for the windows, I love them, not only looks great, they are efficient. Now every window in my home has Renewal by Anderson."

"We had the pleasure recently of having Andersen replace all of our windows. From the very first interaction with the office personnel through the completion of the project, they have been nothing but professional. From Brian our sales rep to Christina the appointment scheduler, they were a pleasure to interact with. Installers Keith, John, and Evan were fantastic to work with. They went above and beyond to repair an area which was slightly damaged during the removal of a window...caulked and painted it. They took extra precaution to ensure the floors were covered while working inside and cleaned up each day inside and out. We love the look of our new windows and can't wait to enjoy the savings in utilities they'll provide. Thanks so much Renewal by Andersen!!"
