This massive crown moulding features crisp details and a bold projection. A combination of contoured and flat moulding details defines the profile. Taller and larger ceilings often require large crown mouldings. Massive crown moulding offers great detail and balanced proportion when dealing with larger interior spaces. Massive crown moulding does wonders for the interior space. It elevates the home's architectural character, refines decor and compliments trim. Massive crown moulding is crafted in durable urethane, one of today's most popular moulding materials. Urethane features a closed cell structure that prevents the moisture absorption that can cause peeling, cracking, staining and decay. Urethane moulding is also pre-primed and ready for finishing.
