Renewal by Andersen: Whole Window Performance

Renewal by Andersen: Whole Window Performance

April 29, 2020

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.

Hear From Our Customers

Jason and Brett did an awesome job installing our doors. We had separate installers a month earlier for our windows who also did a fantastic job. They were all very professional and cleaned up almost better than the area looked before the installation! Since these were both jobs that took more than one day the installers were great at keeping us informed on the status of where the project was at along the way.

This was a great crew to work with. Both the original install manager we worked with (Jay) and the install team (Daniel, Mason, Tony, Ethan, and Jose). Everyone was very professional and knowledgable. They answered all my questions and the end result on the house is great. In 3 days they replaced an old bay window with a new bay window, a set of french doors on the patio with a sliding patio door, and our old front door with a new front door and storm door.

I cant express how happy we are with choosing Andersen for our window installation. Our sales representative was knowledgeable with product and answered any questions we had without hesitation. I did also fill out a survey that was sent in an email, but sadly I failed to personally name the two gentlemen that performed the actual installation. Barrett and Francisco were our guys, and let me tell you, they were outstanding!!! They did Excellent work and were professional as well as efficient and made this a smooth, none evasive process for us. I strongly recommend this company and these installers to anyone in need of windows!!! My husband and I could not be more pleased we chose Andersen for replacing our windows!!!
