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.

"This was one of the best experiences I've ever had with a company. I ordered the windows in November and was told they wouldn't be here until July. That kind of delay the new norm so I wasn't a bit upset with the timeline. I was given an early present when they called to say the windows would be in at the beginning of May. We agreed on the week of May 16th to do the installation, there were 30 windows and a sliding door to install. They arrived promptly on their scheduled install date, and got straight to work. By the end of day one, they had all the upstairs windows complete and their work was incredible. Day two came with more of the same, the crew showed up promptly, got straight to work, and when they left they had every window downstairs installed. The third day they again arrived on-time, and got to work installing the door. The door and windows are perfectly installed. The two lads that did the installation did a phenomenal job, and were friendly to boot. I would give them more business if I had any :) The service I received from the company was great. They kept me abreast of anything that was going on with my order. I appreciate my concierge, Christina, she was good at communicating timelines and getting everything scheduled."

"The two installers were great! They were polite and hard working and they cleaned up all the outside and inside. It was like they were never here. As for the windows, I love them, not only looks great, they are efficient. Now every window in my home has Renewal by Anderson."

"We had the pleasure recently of having Andersen replace all of our windows. From the very first interaction with the office personnel through the completion of the project, they have been nothing but professional. From Brian our sales rep to Christina the appointment scheduler, they were a pleasure to interact with. Installers Keith, John, and Evan were fantastic to work with. They went above and beyond to repair an area which was slightly damaged during the removal of a window...caulked and painted it. They took extra precaution to ensure the floors were covered while working inside and cleaned up each day inside and out. We love the look of our new windows and can't wait to enjoy the savings in utilities they'll provide. Thanks so much Renewal by Andersen!!"
