Exterior Window Headers & Pediments

Exterior window headers and pediments are decorative polyurethane architectural elements installed above window and door openings. They add elegant depth to building facades while naturally shedding rainwater away from window frames. Ideal for classical, neoclassical, and modern villa designs, these polyurethane headers are exceptionally lightweight compared to concrete, stone, or EPS foam, putting zero extra load on the building structure. Thanks to their high-density formulation, they resist impacts, moisture, and extreme weather without cracking, rotting, or warping. Easily paintable with exterior acrylic paints and quick to install, Polure’s high-density polyurethane window crowns offer durable, weather-resistant, and low-maintenance architectural solutions.
