What Are ENERGY STAR® Rated Windows?

When replacement windows are referred to as being ENERGY STAR® rated, it means that they have been manufactured by a designated ENERGY STAR® Partner. ENERGY STAR® rated windows have been independently tested, certified, and verified by the National Fenestration Rating Council (NFRC) to meet or exceed strict energy efficiency standards established by the US Environmental Protection Agency (EPA).

Because we live in a world where energy efficiency is a growing concern, most replacement windows that are manufactured nowadays are ENERGY STAR® rated, regardless of whether they are intended for residential or commercial construction. However, ENERGY STAR® ratings can vary from region to region.

For example, in a Southern climate zone — such as Mississippi — a replacement window needs to have a U-factor of less than or equal to 0.30 in order to be considered ENERGY STAR® rated. In a Northern climate zone – such as Alaska – a replacement window needs to have a U-factor of less than or equal to 0.27 to be deemed ENERGY STAR® rated.

Nowadays, the federal government offers tax credits as incentives to encourage homeowners to install ENERGY STAR® rated windows. However, because there are so many stipulations associated with these tax credits, homeowners should thoroughly research them before investing in ENERGY STAR® windows.

Customer Stories

Don't just take our word for it...

We recently had our home remodeled by the team at Frey Construction. The entire Frey team was professional, experienced, courteous and patient. The final result was exactly how we had envisioned. If we have other home remodeling projects in the future, we would certainly not hesitate to call Frey Construction again.

I am very pleased with Frey Construction. They replaced my roof and gutters. The workers were fast and efficient, and they were always courteous and professional. The office staff was patient and helpful and I appreciated all the time they spent to answer my questions. The quality of work is exceptional and they exceeded my expectations with the clean up afterwards. I highly recommend them!

Frey has done a lot of work for us and the quality is always great. My favorite thing about them is that they are extremely responsive and professional with great customer service. We've previously worked with them on siding and gutters. Most recently I had some windows replaced. They were very helpful and assisted in removing a wall-mounted shelf, which I consider an above and beyond service.
