Doorway Corner Piece
Polure doorway corner pieces add traditional architectural elegance and corner framing to interior door frames, window surrounds, and wall panel moldings. Manufactured from high-density rigid polyurethane (150-220 kg/m³), these decorative corner accents feature wood-like mechanical durability while remaining light enough for effortless handling. Engineered with a closed-cell matrix and water absorption under 1%, they will not warp, swell, rot, or attract insects in humid rooms. They retain dimensional stability from -100 °C / +80 °C and possess a B2 fire safety rating. Delivered pre-primed in white acrylic technical primer, they eliminate complex 45° miter joints by allowing straight butt joints for surrounding moldings. Installation requires applying continuous polyurethane assembly adhesive on all contact surfaces and securing with countersunk screws. Screw holes and seam joints are filled with acrylic filler and sanded smooth prior to painting.
