Door Frame Trim
Polure door frame trim profiles add crisp architectural boundaries and decorative depth to interior doorways and window openings. Engineered from high-density rigid polyurethane (150-220 kg/m³), these casing elements deliver wood-like mechanical durability and impact resistance while eliminating joint cracking, shrinkage, or splitting. Featuring a closed-cell polymer structure with water absorption under 1%, they are unaffected by humidity, moisture, or mold, making them ideal for high-traffic hallways, kitchens, and damp bathrooms. Thermally resilient between -100 °C / +80 °C and rated Class B2 for fire safety, each length arrives pre-coated with factory white acrylic primer. Installation onto doorway surrounds requires cutting 45° miter joints with a fine-tooth miter saw, applying a continuous bead of polyurethane assembly adhesive across rear contact faces and miter edges (silicone is strictly forbidden), and fixing with countersunk screws. Fill screw recesses and joint seams with acrylic putty, sand smooth with 180-220 grit paper, and finish with two coats of paint.
