Exterior Pediments
Polure exterior pediments deliver monumental neoclassical crowns engineered for exterior door portals and facade window surrounds. Precision-molded from high-density rigid polyurethane (150-220 kg/m³), these exterior pediments combine wood-like mechanical durability and hail resistance without imposing dangerous structural loads on outer walls. Featuring a closed-cell polymer structure with water absorption under 1%, they are impervious to rain, snow, freeze-thaw cycles, and mold growth. 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 facade surfaces 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.
Frequently Asked Questions
What density material is used in Polure Exterior Pediments?
Polure Exterior Pediments are molded from high-density rigid polyurethane (150-220 kg/m³), offering wood-like impact strength.
Will Exterior Pediments crack or rot in winter freezing weather?
No, with water absorption strictly under 1%, they will never rot, crack, or swell from rain, snow, or frost.
What adhesive and paint must be used for exterior pediments?
Use polyurethane assembly adhesive combined with screws for mounting (silicone is forbidden). Finish with elastic UV-resistant exterior paint.
How do you prepare Exterior Pediments for final painting?
Fill screw holes and seams with facade filler, sand smooth with 180-220 grit paper, and apply two coats of UV exterior paint.
