Exterior Door Pediments
Polure exterior door pediments crown entrance portals with majestic neoclassical architecture engineered for severe outdoor conditions. Molded from high-density rigid polyurethane (150-220 kg/m³), these facade pediments provide timber-matching mechanical strength and hail resistance without adding structural weight to exterior walls. Featuring a closed-cell polymer structure with water absorption under 1%, they will never absorb rain, rot, freeze-thaw crack, or cultivate mold 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 entrance surrounds requires applying a continuous bead of polyurethane assembly adhesive on rear contact faces (silicone is strictly forbidden), secured with mechanical screw anchors countersunk into the profile. Fill screw holes with facade filler, sand smooth with 180-220 grit paper, and coat with elastic, UV-resistant exterior paint.
