How Do You Know If You’re Truly Getting
An Energy Efficient Window?
It’s confusing . . .having to contend with “less than honest” window companies who claim exaggerated window performance. An NFRC label or label certificate with certified performance ratings provides validated performance in which to compare windows.
The only true way to compare energy ratings on windows is to look at the NFRC certified performance ratings.
NFRC (National Fenestration Rating Council) is a non-profit
organization that administers the only uniform, independent rating
and labeling system for the energy performance of windows, doors,
skylights and related products.
For more information on NFRC, visit www.nfrc.org.
These units refer to model #9200 (Series 4200). For more information go to www.nfrc.org
