Door Header Decoration
Polure door header decorations provide grand architectural framing, pediment scrollwork, and rich relief detailing above interior and exterior door frames, windows, and passage archways. Molded from high-density rigid polyurethane (150-220 kg/m³), these lintel pediments feature wood-like mechanical strength and sharp motif resolution without heavy structural loading. With a closed-cell physical structure absorbing less than 1% water, they resist rot, swelling, and mold growth in humid indoor or outdoor environments. Certified B2 fire class, they remain stable across temperatures from -100 °C / +80 °C. Factory-coated in a white acrylic primer, each piece accepts topcoat paints seamlessly. Installation requires a continuous bead of polyurethane assembly adhesive combined with mechanical screw fasteners.
