St-Laurent Bear Skin

St-Laurent Bear Skin is a fast, effective joint flashing solution designed to protect siding from moisture at butt joints. Each sheet is pre-cut and features a stick-it adhesive backing for quick, tool-free application—just peel, stick, and cover.

Bear Skins are installed under lap siding panels where boards meet, remaining hidden while providing crucial moisture protection. Made from durable materials with a 0-year UV rating (indicating it’s not intended for UV exposure), Bear Skins are perfect for builders seeking efficiency and long-term siding performance.
