Door Crown Moldings
Polure door crown moldings provide sophisticated architectural pediments to crown interior and exterior door frames with classic elegance. Crafted from high-density rigid polyurethane (150-220 kg/m³), these door headers deliver wood-like mechanical toughness and impact resistance. Unlike timber or plaster, polyurethane will not split, warp, or crack under environmental humidity fluctuations or temperatures between -100 °C / +80 °C. Closed-cell polyurethane limits water absorption to under 1%, making these moldings ideal for entryways, kitchens, and bathrooms. Factory-finished with a smooth white acrylic primer layer, they accept topcoat paint seamlessly. Installation involves clean substrate preparation, applying continuous PU assembly adhesive on back faces and join lines, and anchoring with screws. Fill screw countersinks with acrylic filler, sand smooth (180-220 grit), and paint.
