This moulding is basic and versatile in design, and sure to compliment many trim projects. It includes a tapered and unadorned form. When it comes to decor, it is often the little details that add up to have a great impact. Moulding and trim gives the home a refined and polished appearance. It also highlights architectural features. Sill moulding is precision-molded in urethane, a high-density, rigid material that is also light in weight when compared to wood and stone. Non-porous urethane prevents the moisture absorption that can cause peeling, cracking and decay. Sill moulding is pre-primed and ready for finishing.
