Screen Block Screening System
The best of both worlds — a screen porch that easily converts into an enclosed living area without having to remove your screens. Screen Block is the easiest way to enjoy your porch for 3+ seasons.
When it gets cold outside, simply install Winterview clear PVC film to enclose your Screen Block porch. You don’t even have to remove your screen!
Made from flexible, high-quality cellular PVC, the Screen Block system can be used for complex and curved areas of your porch. The low profile system fits into framed openings that is easy to cut and trim with no mitering needed.
Screen Block’s retainer strips hold screen and Winterview plastic film in place and an additional trim piece hides all fasteners in the middle of the track, resulting in a sleek, seamless appearance.
