Renewal by Andersen®’s Focus on Whole Window Performance

Good energy efficiency in windows is an interaction of many factors. Some may contribute more than the others do, but the shortcoming of one could affect the whole window performance on a great scale.

At Renewal by Andersen® of Houston, our windows have excellent energy performance ratings from the National Fenestration Rating Council. Drawing on Andersen’s penchant for innovation, we’ve mastered the art and science of window replacement.

Here are the main contributors to the remarkable energy efficiency of our custom-built products:


Our High-Performance™ Low-E4® glass is the secret behind the amazing reflective and insulating properties of our windows. It features a spectrally selective multi-layer Low-E coating to block the sun’s infrared and ultraviolet rays, which causes excessive heat gain and fading, respectively. At the same time, it allows the entry of most sunshine for adequate daylighting. Our advanced glazing technology involves an argon gas blend and a stainless steel spacer to resist thermal transfer and reduce condensation.

Our Low-E4 SmartSun™ glass makes your home 70% and 45% more efficient in summer and winter, respectively, as compared with ordinary double-pane glass. Despite its superior efficiency rating in cool weathers and hot climates, it virtually has no effect on the clarity and color of the sunlight.

Framing Material

Our casement, bay, bow, sliding, picture, specialty, and double hung windows are all made of Fibrex®, our exclusive composite material. Comprising reclaimed wood fiber and proprietary polymer, it retains its weathertightness with extreme temperature swings and repels moisture. As a result, it is proof against rot and refuses to develop damage to prevent air leakage.

Furthermore, Fibrex is on par with the industry’s best insulating materials, such as wood, vinyl, and fiberglass.

Professional Installation

Our windows are as good as our Certified Master Installers. All members of our crew have passed our strict certification program to ensure we tick the right boxes during installation. We keep workmanship errors to a minimum, delivering flawless work consistently. Plus, thanks to our two-year installation coverage, you can enjoy absolute peace of mind knowing that your windows have protection against premature failures.
