This versatile chair rail features a classic design. Convex and concave portions give the moulding a bold appearance. It measures a lengthy 16 feet. Chair rails are traditionally installed to protect walls, but like other functional architectural elements, the chair rail has gained great decorative value, and today, it is used primary for aesthetic reasons. Chair rail moulding is crafted with detail in high-density polyurethane, a material that continues to win favor for its versatile qualities. Urethane chair rail has the classic character of wood millwork, but thanks to a non-porous construction, it will not peel, crack or decay. This moisture resistance makes urethane great for interior and exterior use.
