Arched Window Trim
An arched window trim (round arch molding) is a semi-circular polyurethane exterior profile designed to elegantly frame curved windows and arched transitions. Ideal for emphasizing windows on classical and neoclassical facades, these polyurethane arch moldings offer a perfectly smooth surface and precise circular form compared to traditional wood or concrete alternatives. Thanks to their lightweight structure, they can be safely installed even on high-rise buildings without any risk of falling. Highly resistant to water, moisture, and UV rays, they do not expand or contract, preventing cracking at the joints. Polure manufactures high-density polyurethane arched window trims with custom molds tailored to various window diameters.
