ISC Marquis Crown Moldings are made from ultra lightweight, high density foam. Our unique manufacturing process gives the foam a completely smooth, white finish that gives a high end look for a fraction of the cost. In addition, our patent pending flat back design allows for the easiest install on the market. Moldings are available in 6 different profiles in 3 different depths (3.5″, 4.5″, 5.5″) to give a ton of design flexibility.
