Interior Door Architraves
Polure interior door architraves create clean, elegant transitions around residential and commercial interior doorways. Molded from high-density rigid polyurethane (150-220 kg/m³), these architraves provide wood-like mechanical durability while remaining light enough to mount effortlessly without heavy structural stress. Featuring a closed-cell polymer structure with water absorption under 1%, they offer complete moisture resistance and mold protection in kitchens, steam-filled bathrooms, and hallways. Operating reliably across temperatures from -100 °C / +80 °C with Class B2 fire safety certification, each length is delivered factory pre-coated with 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 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.
