Understanding the NFRC Label

2015-06-15

Take a look at this guide from our friends at the National Fenestration Rating Council and learn how windows are rated and what that means to you.

There are plenty of measurements that matter when choosing a window that go beyond height and width. The National Fenestration Rating Council (NFRC) provides two visual guides, each helpful in explaining how window performance and quality are rated, and in describing precisely what each rating may mean in your circumstances.

First is an example NFRC label, carefully dissected:1

The NFRC also helpfully explains how the items explored above actually apply to your home, which is in general not obvious to homeowners who haven’t purchased windows before.

If you have questions about how any of the NFRC’s figures apply to your situation, call us to arrange for a consultation.
