Renewal by Andersen: Whole Window Performance

The doors, windows, roof, siding and walls are all part of the thermal envelope of your home. If one of those components is faulty, missing, or of poor quality, that thermal envelope will have a weakness. That’s why it’s important for all components to function properly and to complement each other.

This is also true about the components that are involved in the totality of each of those parts. For example, your windows are not a solid block of one material; they are made up of several materials and other factors that combine to form the whole.

Many manufacturers and sellers of home components like patio doors and windows may talk about one or two features of their products that they are most proud of, but what’s more important for homeowners is to learn about the entire thing.

This is exactly why Renewal by Andersen® is concerned with the “whole window performance” when it comes to its products.

At Renewal by Andersen, we believe that the whole window performance is what truly matters, so we don’t talk about how great one component is without also discussing the contributions of the other parts and factors to the window’s performance. There are three major factors that form the effectiveness and long-lasting functionality of our windows.

Framing Material

Our frames are manufactured using Fibrex, our proprietary material that combines the best qualities of wood and vinyl while also shedding their inherent weaknesses.


Our windows come in different styles, but our standard glass is High-Performance Low-E4 glass. This glass is one of your best options if you’re after longevity, functionality and energy-efficiency. We also offer High-Performance Low-E4 SmartSun and High-Performance Low-E4 Sun, both glass options that can protect your indoors from heat transference more effectively.


Our windows are great, and we match them with our installation. Only our technicians are allowed to install our windows, and we back every installation with a warranty separate from the warranty covering our window products.
