Energy Efficient Windows

When selecting your new windows be sure to ask about the Energy Rating Label from the National Fenestration Ratings Council (NFRC). Each label includes a rating for the U-Factor and Solar Heat Gain. These rating numbers help consumers identify the heat loss or gain a window sustains. These ratings are important because your new windows should help control the temperature regulation throughout your home.

U-Factor measures heat loss and heat infiltration through conduction, while Solar Heat Gain measures heat gain through UV rays. A low U-Factor rating indicates your new windows are well insulated and resistant to heat flow, helping keep the warmth in during the winter and the cool air in during the summer.
