Series 500 single hung windows are a great choice for traditional styling and high performance in a lower-priced window. They include most of the features found in our popular double hung windows, and the fixed upper lite can be curved to form elegant archtops.
Series 500 windows are versatile. They can be connected (mulled) together with other windows to form twins, triples, bays, bows and stacks. The configurations are virtually unlimited!
At the heart of each Series 500 Single Hung Window is our polymer thermal barrier. This special barrier separates the interior and exterior of the window throughout the entire frame and sash, dramatically reducing heat loss in the winter and heat gain in the summer.
Series 500 Standard Features
Our Thermal Barrier aluminum windows and sliding glass doors feature a durable, maintenance-free powder coat finish in your choice of five Standard colors (below, left). Custom colors and anodized finishes (below, right) are available for an additional charge*.
