U-Factor: What Is It And How Can It Benefit Your Home?

If you’ve been looking for new doors in Austin Texas & surrounding areas, chances are you’ve encountered a few terms you may have not been familiar with. One such term is U-Factor. You can see this term on labels from the National Fenestration Rating Council (NFRC) or from ENERGY STAR®. As you may know, these two organizations provide ratings on the energy performance of doors, windows, and skylights (among many other things). Now, let’s discuss U-Factor.

U-Factor: Keeping Heat In & Out

Simply put, it is a measurement of how well a product is at preventing heat from escaping a building. Normally, products have a rating that falls between 0.15 and 1.20. The lower the U-factor rating of a product, the better that product is at keeping heat inside your home. Although U-factor is commonly associated in regions where heating is vital to keep comfortable, those of us here in Texas, where the climate can get hotter, can also benefit from it. How?

If a product is good at keeping heat in, then it can also be good in keeping heat out.

That means whether it gets too hot outside or too cold, your heating and cooling systems don’t need to work overtime to keep your home more comfortable. Of course, the less time you use your air conditioning or heaters, the less power you consume, and the lower your electric bill will be.
