How Replacement Windows Improve Your Energy Efficiency

One of the easiest and, arguably, best ways to improve your energy efficiency is with a house window replacement or an entry or patio door upgrade. Replacing all exterior doors and windows in your house can save you up to 10% on your annual energy bills. What’s more, these types of remodels and projects can be done any time of the year, allowing you to maximize the seasonal benefits that these products bring.

Replacement Windows

Unfortunately, not all doors and windows are created equal. It’s important to know the qualities that make for an efficient window in order to reap its benefits. Here are a few tips from our experts at Renewal by Andersen® of Memphis on how to use your replacement windows and patio doors to increase the energy efficiency of your home.

Double and Triple-Pane Windows

Talk to your window replacement service about getting double-pane windows on your next upgrade. Double-pane windows are so named because they have a layer of inert insulating gas sandwiched between two glass panes. This gas helps increase insulation, keeping your interiors warmer in the winter and cooler in the summer. Triple-pane windows work similarly except they have two gas layers alternating between three panes of glass.

Mind the Numbers

The NFRC uses standard performance ratings to give consumers a good idea about the energy efficiency of replacement windows and doors. There are a lot of ratings but the most important ones are R-values and Solar Heat Gain Coefficient or SHGC. Higher R-values mean better insulation. On the other hand, a lower SHGC means the window transmits lower amounts of heat even under direct sunlight.

Professional Installation

None of these features will mean anything if your window company installs your doors or windows incorrectly. Make sure you hire only trained and licensed professionals to handle your door and window replacement so you can make the most of the performance benefits of your chosen products.

"The men who came out were able to work with each other good and professional showing us how the job would start and how long it would take. While they were doing their job they saw that the windows sills were off balance and very diligent and made it repairable to place the new windows in they cleaned up the area where they were working and made it look like no one had been there. They were very polite."

"I have purchased 16 Anderson windows and they are great. The windows are perfect but the installation was the best. It is a joy having these windows in my 1910 home."
