Decorative Arch Pediment

Polure decorative arch pediments bring classic curved pediment headers and architectural prominence to interior doorways, exterior entry portals, and window alcoves. Manufactured from high-density rigid polyurethane (150-220 kg/m³), this pediment delivers timber-like mechanical strength and carved detail while eliminating structural dead weight. Featuring closed-cell composition with under 1% water absorption, it will not rot, warp, swell, or foster mold in humid interiors or exposed facade environments. Engineered to endure temperature extremes from -100 °C / +80 °C and rated B2 for fire safety, every pediment comes factory-coated with a white acrylic technical primer. Installation requires level positioning, applying continuous polyurethane assembly adhesive on rear contact faces AND joining edges, and screw attachment into mechanical anchors. Fill countersunk screw heads and joints with acrylic or facade putty, sand smooth (180-220 grit), and finish with topcoat paint.
