What Renewal by Andersen®’s “Whole Window Performance” Means

With the prices of energy nowadays, homeowners are continuously looking for ways that can help them reduce what they spend on their energy bills. One way that they can lower their energy bills is by picking the right replacement window for their homes. This is where the “whole window performance” of Renewal by Andersen® comes in.

Here is everything you need to know about the “whole window performance” of Renewal by Andersen windows.

What is the Whole Window Performance?

When it comes to making homes more energy efficient via the windows, most window companies tout the specific components of their windows that can help achieve efficiency. Renewal by Andersen, on the other hand, goes a step further by looking at the bigger picture and paying particular attention to everything that makes up a window, such as the glass, frame and installation. This is known as the whole window performance and it’s what allows the double-hung or custom windows of Renewal by Andersen make your home more energy efficient.

The Components of a Window With Whole Window Performance

As stated before, a Renewal by Andersen window with the whole window performance is composed of three components. The first one is the framing material of the window. Since the 1970s, Renewal by Andersen has used Fibrex® frames on their windows, which not only guarantees that your windows will last for a long time but also prevents heat loss in the winter and reduces your home’s heat gain in the summer.

The second component that makes up a quality Renewal by Andersen window is the glass. Renewal by Andersen offers homeowners three different glass options for your window: the High-Performance™ Low-E4® glass, High-Performance Low-E4 SmartSun™ glass, and the High-Performance Low-E4 Sun glass. Regardless of what glass type you choose, your window is bound to make your home more energy efficient by reducing undesirable solar heat gain in your home.

Of course, neither the glass nor the framing material of your window will matter much if the window itself isn’t properly installed. This is where the final component of the whole window performance comes in: the installation. If you want the whole window performance in your home, make sure to only hire a Renewal by Andersen certified master installer to attach your new windows to your home. That way, any mistakes that reduce the windows’ whole window performance capabilities can be avoided.

"I highly recommend Renewal by Andersen. We were treated well and everything went smoothly from start to finish. The company kept in contact with me before, during, and after the installation and let me know what to expect. I'm in love with my new windows! I will be using this company again when we refinish our basement. "
