Polyurethane Overdoor Pediment
Polure polyurethane overdoor pediments create commanding portal entrances, classical triangular crowning friezes, and elegant architectural frame crowns above interior and exterior doors. Molded from high-density rigid polyurethane (150-220 kg/m³), these overdoor pediment moldings feature wood-like mechanical durability and crisp profile sharpness without sagging or splitting. Incorporating a closed-cell physical structure with water absorption under 1%, they will not warp, swell, rot, or cultivate mold in humid environments or exterior building portals. Certified B2 fire class, they remain stable across temperatures from -100 °C / +80 °C. Factory-coated in a white acrylic primer, each piece accepts topcoat paints seamlessly. Installation requires a continuous bead of polyurethane assembly adhesive combined with mechanical screw fasteners.
Frequently Asked Questions
What material is the Polure polyurethane overdoor pediment manufactured from?
Polure polyurethane overdoor pediments are manufactured from high-density rigid polyurethane (150-220 kg/m³), ensuring B2 fire class safety and wood-like impact strength.
Can polyurethane overdoor pediments be installed on exterior doors?
Yes. Water absorption is under 1% and thermal stability spans -100 °C / +80 °C. Outdoor installation requires an elastic UV-resistant exterior paint.
What adhesive is required to install a polyurethane overdoor pediment?
Continuous polyurethane assembly adhesive must be applied along rear contact faces with mechanical screw fixings. Silicone adhesive is forbidden.
How should polyurethane overdoor pediments be prepared prior to painting?
Lightly sand the factory white acrylic primer with 180-220 grit sandpaper to remove residue, then apply two coats of topcoat paint.
