Our thermal-barrier Single Hung Windows are designed for homeowners who want traditional styling in a lower-priced window. Our Series 500 window has a special polyurethane thermal barrier. Separating the interior and exterior of the aluminum frame, the barrier dramatically reduces heat loss in the winter and heat gain in the summer.
Approximately 75% of a window's surface is glass. Our 7/8" insulated glass units provide the optimum air space available. Their double strength glass provides superior insulation. They are warranted for 10 years against seal failure. Some of our other insulated glass options are: Argon gas fill, tinted glass and Thermal Low-E Energy Saver Glass.
The Series 500 Single Hung Window is an innovative combination of superior materials, energy-saving technology, and beautiful styling. We believe it is America's finest window!
