Avoid having uncomfortable drafts in your home by installing replacement windows that meet the air leakage rating requirements by the NFRC. Today, Renewal by Andersen® of Greater Philadelphia explains everything you need to know about air leakage.
What Is Air Leakage?
The National Fenestration Rating Council (NFRC) rates the energy performance of windows according to several measurements: U-Factor, solar heat gain coefficient (SHGC), visible transmittance and air leakage. The air leakage rating is a measurement of the amount of air that can penetrate through a window and into your home. The lower the air leakage rating of a window, the better.
Where Can I Find Good Air Leakage Ratings?
Look for windows from manufacturers that display the NFRC label on their products. Windows with this label meet the NFRC’s high standards for product performance and energy efficiency. At Renewal by Andersen of Greater Philadelphia, we proudly display the NFRC label on all our window replacement products.
How Does Air Leakage Affect Me?
Windows that don’t meet air leakage requirements may end up performing much less efficiently than better-rated ones. When a window is leaky, your home may be exposed to drafts. This can lead to an uncomfortable home, higher energy bills and even moisture damage issues throughout your property.
