Exterior Window Pediments
Polure exterior window pediments crown window openings with timeless neoclassical elegance and structural weather resilience. Precision-molded from high-density rigid polyurethane (150-220 kg/m³), these facade pediments provide wood-like mechanical durability and hail resistance without adding dangerous weight to the exterior wall. Featuring a closed-cell polymer structure with water absorption under 1%, they will not absorb rain, rot, freeze-thaw crack, or swell under extreme weather. Thermally stable from -100 °C / +80 °C and rated Class B2 for fire safety, each pediment comes pre-coated with factory white acrylic primer. Installation onto exterior wall surfaces requires applying continuous polyurethane assembly adhesive across back contact faces and joining seams (silicone is strictly forbidden), secured with mechanical screw anchors countersunk into the material. Fill screw holes with facade filler, sand smooth with 180-220 grit paper, and coat with elastic, UV-resistant exterior paint.
