Exterior Window Arch

An exterior window arch is a decorative architectural molding designed in curved or straight forms to frame the upper window openings on building facades. Used in exterior designs, these arches highlight window borders, add depth to the facade, and protect the building by shedding rainwater away. Compared to heavy concrete or marble alternatives, polyurethane exterior window arches are extremely lightweight, placing no extra load on the building's structure. Waterproof and highly resistant to moisture, UV rays, and freeze-thaw cycles, this durable polyurethane structure will not crack, peel, or warp under harsh weather conditions. Easily cut and paintable with any exterior paint, they can be quickly installed using adhesive and screws. Polure manufactures premium window arches using high-density polyurethane, ensuring maximum weather resistance and long-lasting structural integrity.
