Exterior Window Arch Moulding

Exterior window arch moulding is a curved architectural profile designed to frame the arched upper portion of windows. It serves both an aesthetic purpose and a functional one by diverting rainwater away from the facade. Installed at the top of arched window frames, these curved mouldings seamlessly connect with straight side trims to create a cohesive, elegant window casing. Unlike EPS (foam) trims, which are easily damaged by birds and impact, or heavy plaster mouldings that add unnecessary weight to the building, polyurethane arch mouldings offer high impact resistance and lightweight durability. Thanks to their fully waterproof structure, they are highly resistant to moisture, frost, and UV rays, ensuring they won't crack, rot, or peel over time. Easily cut and joined on-site, these profiles can be painted with exterior paints for a quick, hassle-free installation. Polure’s high-density polyurethane exterior arch mouldings deliver long-lasting insulation and timeless aesthetic value to your architectural projects.
