Titanium Oxide Coatings: How Do They Work?

Renewal by Andersen® replacement windows come with High-Performance™ Low-E4® glass. In addition to its energy-saving features, it features an exterior titanium dioxide layer that makes our replacement windows virtually self-cleaning. Learn about the features that make our replacement windows easy to clean and maintain.

Titanium Oxide Coatings: How Do They Work?

How It Works

A thin layer of titanium dioxide is applied to the exterior surface of our High-Performance Low-E4 glass during manufacturing. This outside-facing layer is activated by ultraviolet (UV) rays from sunlight, a process called photocatalytic action. What it does is it loosens particles above the titanium dioxide layer: dirt, stains amd even hard-to-remove water spots. Everything eventually just falls off.

If the window is wet from rainwater or from when you’re washing your windows, it simply dries clean under direct sunlight. This same layer also helps filter UV rays and protect indoor fabrics and furniture.

Other Features

Our High-Performance Low-E4 glass packages boast a multitude of features that contribute to what makes our windows some of the most energy-efficient on the market. The standard double-pane assembly is separated by insulated spacers. When set into our exclusive Fibrex® material frames, it allows minimal thermal transfer, which helps keep indoor temperatures comfortable and consistent, reducing heating and cooling requirements. The space between the two glass panes can be optionally filled by a custom argon gas blend. As an inert gas, argon can enhance window glass insulation, which can further improve energy efficiency.

Our operable window styles are likewise easy to clean, with sashes that can be removed (sliding windows), tilted (double hung windows) or reached around (casement windows). The Fibrex material frames feature have the same low-maintenance properties of vinyl frames.

"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."
