HOW TO SELECT ENERGY-EFFICIENT WINDOWS

Buying energy-efficient windows involves a lot of research. In many cases, the prettiest units don’t necessarily perform the best. Today, Renewal by Andersen® of St. Louis shares ways to select the products that can help reduce your energy costs over the long term:

How To Select Energy Efficient Windows

Look for the ENERGY STAR® Seal

As with exterior doors, code-compliant windows bear the ENERGY STAR® symbol. It’s the stamp of approval given by the federal government to products designed to deliver maximum performance while economizing on energy. The Environmental Protection Agency also makes sure that the units have the necessary features to meet the performance that consumers demand.

The EPA revises its specifications from time to time. New federal minimum efficiency requirements and technological advances are the usual catalysts for changes in standards.

Read the NFRC Label

Any experienced windows company would agree that the National Fenestration Rating Council (NFRC) label determines which ENERGY STAR-labeled products are suitable for each region. For examples, units that meet the standards in Alaska are not always good for Texas.

The NFRC label can feature up to five energy ratings, but focus on U-factor and Solar Heat Gain Coefficient (SHGC). The former refers to the unit’s insulating quality while the latter pertains to its ability to deflect solar heat. In the St. Louis County, the ideal combination is a 0.30 U-factor (or less) and a 0.40 SHGC (or less).

Think About Durability

Pay attention to the framing material of the unit to gauge its sturdiness over the long term. The most durable replacement windows have frames that don’t rot, crack or bow. Our exclusive Fibrex® material can retain its structural integrity for more than 35 years, staying draft-free for decades.

Put a Premium on Installation

To prevent air leakage, make sure your new windows are installed to perfection. Hire a company that doesn’t use subcontractors. We train our own crew to master the installation of our custom-manufactured products. As a result, our Certified Master Installers eliminate workmanship errors and ensure our windows work as expected for a long period.

"Renewal was fantastic! They kept you in the loop from ordering to installation. They informed you at every step of the process of what was happening. The installers were kind, courteous, and professional. Everything was cleaned up after the installation. It was as if they hadn't been there except to see your beautiful new windows. I highly recommend them."

"3rd time using RBA for window replacement. Again, a very positive experience, the windows are great, the installation was done right, the professionalism was apparent from start to finish. Still have existing windows to be replaced and will definitely use RBA again to do it in the future."

"Renewal by Andersen was a good experience for us in replacement of our windows. From the initial meeting with the sales representative, Leslie, through the waiting period for manufacturing, and then to the installment process, our experience was excellent! Communication is key for me and we were kept informed and updated as our windows were being ordered and manufactured. Calls to update us on the installation process were welcomed and appreciated. They know how much is too much so they don't pester you with unnecessary contact. We love our new windows!!! Did I say that already??😂 We can tell a major difference in reduced Street noise and also the temperature at our windows. Excellent company, highly recommend!!"
