ABSTRACT:
A sill pan system is provided for installation along the bottom plate of a framed-in window or door opening to prevent water leakage. The system includes end pieces that are fitted in the bottom corners of the opening and a central web that spans, partially overlaps, and is adhered to the end pieces. The central web is formed of a transparent or translucent plastic to allow visual confirmation that a good seal is formed between the overlapping portions of the web and end pieces. The web is formed with inside flanges and flashing strips that are connected with flexible hinges so that web material can be rolled into a roll. The components may be formed with an abrasion resistant upper surface cladding and the central web may be formed with longitudinally extending drain channels for directing water to the ends of the pan for drainage.
