Overdoor Pediment Decoration
Polure overdoor pediment decorations provide architectural entrance crowns, broken pediment crests, and supraporte relief arches above interior doorways and exterior main portals. Molded from high-density rigid polyurethane (150-220 kg/m³), these overdoor pediments offer wood-like mechanical durability and crisp detail without warping or cracking overhead. Incorporating a closed-cell physical structure with water absorption under 1%, they will not swell, rot, or cultivate mold in humid indoor atmospheres or outdoor porticos. 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 overdoor pediment decoration manufactured from?
Polure overdoor pediment decorations are manufactured from high-density rigid polyurethane (150-220 kg/m³), ensuring B2 fire class safety and wood-like impact strength.
Can overdoor pediment decorations be installed on exterior main entrances?
Yes. Rigid polyurethane resists moisture (water absorption <1%) and freeze-thaw cycles. Exterior paint with UV resistance is required.
What adhesive is required to install an overdoor pediment decoration?
Continuous polyurethane assembly adhesive must be applied along rear contact faces with mechanical screw fixings. Silicone adhesive is forbidden.
How should overdoor pediment decorations 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 paint.
