Arched Window Trim Designs
Arched window trim designs are decorative architectural profiles applied to the top of interior or exterior windows to create elegant oval, circular, or Gothic arches. Designed to replace traditional stone or concrete headers, these polyurethane window arches add depth and a classic aesthetic to any facade. Unlike heavy masonry, polyurethane arches are exceptionally lightweight and fast to install. Their waterproof nature provides an excellent moisture barrier, preventing rot and decay. Engineered to withstand thermal expansion, they won't crack at the joints and can be painted directly with exterior paint. Polure manufactures high-density polyurethane window arches in various radii to fit any window span perfectly.
