This crown moulding features a simply elegant concave profile. Concave moulding creates a smooth and attractive transition between wall and ceiling. At 7 5/8" in height, this crown moulding is larger in size and perfect for larger and higher ceilings. It conceals and ornaments the juncture of wall and ceiling while accentuating the shape and depth of the interior space. Massive crown moulding has the beauty and character of traditional moulding, but it is molded in urethane, a high-density polymer material that is truly versatile. Lightweight urethane moulding installs with ease. It is also moisture-resistant, so it does not absorb the moisture that can cause peeling, cracking and decay.
