Interior Door Pediments
Polure interior door pediments deliver refined architectural crowning profiles designed for internal residential doorways and hallway portals. Molded from high-density rigid polyurethane (150-220 kg/m³), these interior pediments 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 pediment comes factory pre-coated with white acrylic primer. Installation onto doorway surrounds requires applying a continuous bead of polyurethane assembly adhesive on rear contact faces (silicone is strictly forbidden), combined with countersunk mechanical screws. Fill screw recesses and joint lines with acrylic putty, sand smooth with 180-220 grit paper, and finish with two coats of paint.
