Ph: 888/256-2599

Operable, acrylic block single-hung and sliding styles, custom radius shapes and circle tops, casements and awnings are available from U.S. Block Windows in virtually any height and width. The block size is 6 inches by 3/4-inch—the narrow profile of the block enabling the operating sashes to slide by each other. Both single-hung and sliders come in several standard sizes in vinyl. Special sizes and radius tops are also available. Casement and awning windows are also available that crank out, with block sizes available in 6 inches or 8 inches. Energy Star-rated options are also available. In addition, the manufacturer features Line Hinge operable acrylic block windows, a patented window system providing unique weight and load distribution capability. The windows come with a unique snap-in, all-vinyl and hardware-free screen with no springs, tabs, pins, or metal hardware.
