Classical Door Crown
Polure classical door crowns introduce stately architectural grandeur, pediment molding, and rich relief detailing above interior and exterior door portals, window frames, and grand archways. Molded from high-density rigid polyurethane (150-220 kg/m³), these door pediments provide wood-like mechanical durability without adding heavy structural loads or warping over time. Featuring a closed-cell physical structure with water absorption under 1%, they will not rot, swell, or cultivate mold in humid interior or exterior environments. Certified B2 fire class, they remain stable across temperatures from -100 °C / +80 °C. Pre-coated in a factory white acrylic primer, each crown accepts topcoat paints seamlessly. Installation requires a continuous bead of polyurethane assembly adhesive combined with mechanical screw fasteners.
