Exterior Window Pediments
Polure exterior window pediments provide grand architectural headers, triangular or arched pediment crowns, and distinguished relief detailing above exterior windows and main entry portals. Molded from high-density rigid polyurethane (150-220 kg/m³), these facade pediments deliver wood-like mechanical durability and impact resistance without adding heavy structural loads or denting in severe weather. Featuring a closed-cell physical structure with water absorption under 1%, they will not rot, swell, distort, or cultivate mold in wet climates. Certified B2 fire class, they remain stable across extreme outdoor temperatures from -100 °C / +80 °C. Factory-coated in a white acrylic primer, each piece must be painted with a high-grade elastic UV-resistant exterior paint. Installation requires a continuous bead of polyurethane assembly adhesive combined with mechanical screw fasteners.
Frequently Asked Questions
What material is Polure exterior window pediment manufactured from?
Polure exterior window pediments are manufactured from high-density rigid polyurethane (150-220 kg/m³), providing wood-like strength and B2 fire class rating.
Are exterior window pediments resistant to severe weather and hail?
Yes. With high density (150-220 kg/m³) and water absorption under 1%, polyurethane pediments will not dent in hail, rot, swell, or warp from frost.
What adhesive and fixings are required for exterior window pediments?
Continuous polyurethane assembly adhesive must be applied along rear contact faces with mechanical screw fixings. Silicone adhesive is forbidden.
What paint should be applied to exterior window pediments?
After sanding the white acrylic primer with 180-220 grit paper, apply an elastic, UV-resistant exterior facade paint to prevent UV degradation.
