Interior Door Trim
Polure interior door trim profiles refine doorway surround transitions with sleek architectural lines and enduring material performance. Precision-molded from rigid high-density polyurethane (150-220 kg/m³), these casing profiles offer wood-like mechanical durability and impact resistance without the splitting, shrinking, or warping common to timber. Featuring a closed-cell polymer structure with water absorption under 1%, they resist humidity, steam, and mold growth, making them perfect for bedrooms, hallway passages, kitchens, and bathrooms. Thermally stable from -100 °C / +80 °C and rated Class B2 for fire safety, each length is delivered pre-coated with factory white acrylic primer. Installation requires cutting precise 45° miter joints with a miter saw, applying a continuous bead of polyurethane assembly adhesive on rear contact faces and miter joints (silicone is strictly forbidden), and fixing with countersunk screws. Fill screw recesses and joint lines with acrylic putty, sand smooth with 180-220 grit paper, and finish with two coats of paint.
