Vinyltek Casement Window NFRC Testing

NFRC Testing

Vinyltek casement window score

Bet you didn’t know the Vinyltek casement window scored the highest marks when tested by NFRC labs in Washington DC!

That’s a great accomplishment for any window, considering we tested against 22,000 other windows, yep 22,000; not 2200, not 220.

The highest test results in 22,000 lab tests and simulations. Another reason Vinyltek’s windows are substantially better than any other window you might be considering.
