Accentuate doors and windows, and take exterior decor to the next level with urethane moulding. Detailed moulding improves doors and windows while enriching the exterior overall. This bold moulding is 12 feet in length, so it is large enough to accommodate larger projects. Urethane door and window moulding also works well with other decorative accents, like pediments, crossheads, pilasters and more. Urethane molds with great detail and depth. The beauty of urethane millwork is on par with classic materials like wood; however, urethane offers excellent moisture-resistance. Urethane's closed cell structure blocks much of the moisture that can cause peeling, cracking, and decay wood moulding.
