The NFRC is responsible for determining a window’s overall performance, allowing consumers to make an educated decision before they purchase new windows or doors. Each window and door is rated on its ability to keep warm air out in the summer and cold air out in the winter, in addition to how well it resists wind and condensation. This rating system ultimately determines the energy efficiency of a product.

The two most important values to look for are U-Value (also commonly called U-Factor) and Solar Heat Gain Coefficient (SHGC). The lower the U-value, the greater a window’s resistance to heat flow and the better its insulating value. SHGC is a number between 0 and 1that indicates the fraction of heat from the sun entering through your window. The lower this rating is the less heat will be allowed to pass through you windows. This rating is important in the warmer months. A low rating results in a cooler him during the summer. At Power Home Remodeling Group, LLC, we are proactive in making sure our products rate well below state requirements for both U-Value and SHGC.

Our windows are able to achieve some of the best performance ratings in the industry thanks to our advanced technology:

• Sashlite®
• HeatShield™
