Choosing replacement windows for your house can be equal parts exciting and overwhelming. From the style to frame material to energy efficiency ratings, you have many things to consider when making your selection. In today’s post, Renewal by Andersen® of Cape Cod, a top local window contractor, sheds light on the energy efficiency component of a window and how the NFRC label can guide you in your purchasing decisions.
The National Fenestration Rating Council (NFRC) ranks the energy efficiency of replacement windows. The windows offered by your local window company will should have NFRC labels clearly visible on the frame or the glass. These labels display the energy performance ratings of the unit, including:
- Solar Heat Gain Coefficient (SHGC): This is a measure of how much of the sun’s heat is transmitted by the window. The higher this number, the better the window is at letting heat inside your home, which can be problematic on hot days.
- U-Factor: This is a measurement of the insulating ability of replacement windows. A higher U-factor is preferable in climates that experience hot summers and cold winters. Temperate areas do not need extremely high U-factors to o perform well.
ENERGY STAR® Label
In addition to the NFRC label, the Department of Energy also identifies products that have high energy efficiency ratings with an ENERGY STAR® certification. It’s always a good idea to look for the green star logo on the replacement window you’re considering. If the product doesn’t have this label, you’re probably better off purchasing something else.
