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.
