We are the first to manufacture a "molded" polystyrene foam crown molding in North America! Our crown moldings install with simple painters caulk without the need for nails or fasteners to install. Our crown moldings have a patent pending flat back design that allows it to be cut in most positions in most miter saws. Because of our design, it works great for installing indirect LED lighting without the need to block behind the molding. Visit our website or give us a call today! creativecrown.com/
