Series 700 Double Hung Windows

Series 700 bronze window

At the heart of each Series 700 Double Hung Window is our 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 percent of a window's surface is glass. Our 7/8" insulated glass units have the optimum air space available. Made with double-strength glass, they provide superior insulation. They are warranted for 10 years against seal failure. Some of our other insulated glass options are: Argon gas fill, tinted glass, ThermalSafe laminated glass and Thermal Titanium low-E Energy Saver Glass.

The Series 700 Double Hung Window is an innovative combination of superior materials, energy-saving technology, and beautiful styling.

We believe it is America's finest window!
