Urethane trim accents walls and more. Trim emphasizes the depth and shape of the interior space. Our versatile trim can also be used to accents windows, doors, furniture and more. The possibilities are many when you choose our durable and cost-effective urethane products. Urethane trim is lightweight and easy to work with. It can be installed like wood, and has a weight and feel similar to that of pinewood. If you are searching for an alternative to wood, urethane has much to offer. The closed cell structure of urethane limits moisture absorbency and leads to high-performance and little maintenance in interior and exterior applications.
