What Makes an Energy-Efficient Window? Look for the NFRC Label

This spring and summer, the temperature in Maine can run as high as the 80s and adding insulation can help residents keep their homes comfortable all year round. However, as it turns out, according to the Alliance to Save Energy, about half of the homes in the United States don’t have enough insulation. This is just one area to check in making a more energy-efficient home, and homeowners are continually encouraged to determine where efficiency can be improved and figure out which parts of their property need attention.

Covering up leaks that allow humid air to slip into your house is another practical step to minimize cooling bills. Such leaks can be found in your basement or attic but are more often caused by faulty doors and windows. But not all windows are created to comply with energy-efficiency standards. When planning for replacement windows in Maine, consider this advice:

With the current emphasis on energy efficient windows, the National Fenestration Rating Council has designed an energy-performance label to guide contractors and homeowners in their search for the perfect window. Since the climates in different parts of the United States vary widely, checking the label before ordering the window can make a big difference in how much the window can help your client keep energy costs to a minimum.

NFRC Certified (upper left corner) indicates that the National Fenestration Ratings Council has licensed the window’s manufacturer and certified the window’s performance in accordance with NFRC’s standards. The upper right corner identifies the window’s manufacturer, model, style and the materials used in its construction.

The same advice applies to homeowners who are planning to hire contractors for replacement windows in Southern Maine. It is recommended to replace old, leaky windows with higher-efficiency models such as Fibrex, made of composite grain materials and melded to create an environmentally-friendly product.  Fibrex is carried by Renewal by Andersen of Maine, the exclusive supplier of Renewal by Andersen replacement windows that bear the NFRC Label.
