Polyurethane Arch Molding
Polure Polyurethane Arch Molding provides smooth curved architectural contouring for interior arched doorways, windows, and decorative wall recesses. Molded from high-density rigid polyurethane (150-220 kg/m³), this trim delivers wood-like mechanical toughness while providing flexible adaptability for rounded structural contours. Its closed-cell structure keeps water absorption under 1%, protecting against rot, swelling, or mold in humid interiors and exterior entries. Dimensionally stable across temperatures from -100 °C / +80 °C, it meets B2 fire safety standards. Installation requires applying a continuous bead of polyurethane assembly adhesive along wall contact edges and butt joints, reinforced with mechanical screw fixings; silicone is strictly forbidden. Countersunk screw heads and joint seams should be filled with acrylic filler and sanded smooth using 180-220 grit paper. Factory-prepped with white acrylic primer, it accepts any standard water-based interior or exterior paint system.
