Flat trim moulding is among our most basic trim products. This simple moulding becomes a versatile addition to your latest projects, whether it is used to create a simple window casing or used in conjunction with a larger wall moulding. Flat trim moulding is crafted in urethane. Urethane molds with the fine detail and classic character required to recreate the traditional trim product for today's do-it-yourselfers. Urethane is rigid and strong, but also lightweight and easy to work with. Urethane trim has a weight and feel similar to that of pinewood. Urethane trim is also non-porous. This quality locks out moisture and prevents warping, cracking, peeling and decay.
