This moulding measures 16 feet in length. It features classic contours and a versatile design that can be applied to many exteriors. This moulding is crafted in urethane, a material that performs exceptionally well in exterior applications. Rigid, high-density urethane is a polymer material that offers outstanding detail, moisture-resistance and affordability. Trimmed doors and windows have a great impact on the home exterior because it is often the little details that add up to make a difference. Detailed moulding highlights and refines doors, windows, entryways and more. A durable urethane construction protects against peeling, cracking, staining and decay. Urethane door and window moulding arrives pre-primed and ready for finishing.
