Owens Corning FS3550BK is a polyethylene foam sill sealer roll designed to provide resilient sealing between a foundation wall and sill plate. The 3.5 in. wide by 50 ft. long roll with 0.1875 in. (3/16 in.) thickness reduces air leakage, resists moisture migration from the foundation into wood structures, and serves as a barrier to insects for new and retrofit construction. The material can be trimmed for a precise fit.
