Polure Exterior Wall Pediments
Polure exterior wall pediments deliver grand architectural crowning elements for building facades, entryways, and window surrounds. Molded from high-density rigid polyurethane (150-220 kg/m³), these pediment moldings offer wood-like mechanical durability and impact resistance without warping, cracking, or splitting under severe exterior conditions. Featuring a closed-cell polymer structure with water absorption under 1%, they provide complete immunity to heavy rain, frost, rot, and swelling. Operating reliably across extreme temperatures from -100 °C / +80 °C with Class B2 fire safety certification, each pediment comes factory pre-coated with white acrylic primer. Exterior installation requires applying continuous polyurethane assembly adhesive to contact faces and joining seams (silicone is strictly forbidden), combined with compulsory mechanical screw fixing. Recessed screw holes and joints are filled with exterior putty, sanded smooth with 180-220 grit paper, and painted with UV-resistant exterior paint.
