Total Window U-Value
 Windows with a U-Value lower than .30 qualify for a stimulus tax credit.
All Hayfield windows are manufactured with the DuraLite® Spacer bar. All test results are with the DuraLite Spacer bar.
Dura Platform Spacers improve the total window U-value.
Warmer window U-values makes you feel more comfortable.
Simulations were performed by Enermodal Engineering Limited using Window 5.2 and Therm 5.2 as per NFRC 100, and NFRC 500, 2001. Generic vinyl window, soft coat Low E (e=0.034), argon filled.
DuraLite is a registered trademark of Envirosealed Windows.
