Decorative Window Pediments
Polure decorative window pediments bring classic architectural majesty and ornate sculptural details to window surrounds. Precision-molded from rigid high-density polyurethane (150-220 kg/m³), these pediment elements provide wood-like mechanical durability and intricate relief work without expanding or warping. Featuring a closed-cell polymer structure with water absorption under 1%, they offer total protection against humidity, moisture, and mold in interior and exterior applications. Operating reliably across a broad temperature range from -100 °C / +80 °C with Class B2 fire safety certification, every pediment comes factory pre-coated with white acrylic primer. Installation onto wall surrounds requires continuous polyurethane assembly adhesive applied to rear contact faces and miter joints (silicone is strictly forbidden), combined with countersunk mechanical screws. Fill screw recesses and miter seams with acrylic putty, sand smooth with 180-220 grit paper, and finish with two coats of paint.
