The patent-pending Protecto Sill Drainage System combines the maker's peel-and-stick adhesive with sloped, closed-cell foam that ensures any water or condensation found inside window openings will be directed to the outside weather plane of the structure. Accommodating either 2x4 or 2x6 framing, the system also features a mold-resistant wicking material to absorb and transfer moisture to the outside of the window opening. It also features a 1/2-inch back dam for additional drainage and protection. 800-759-9727. www.protectowrap.com.
