Door Crown Pediment
Polure door crown pediments frame main entryways and interior doorways with classic architectural grandeur, pedimented headers, and elegant shadow lines. Manufactured from high-density rigid polyurethane (150-220 kg/m³), this entryway crown provides wood-like impact strength and sharp carved detailing while remaining lightweight to prevent wall strain. Featuring closed-cell waterproofing with under 1% water absorption, it will not rot, warp, swell, or foster mold on exterior entrances or in humid interior foyers. Engineered to endure temperatures from -100 °C / +80 °C with B2 fire safety compliance, every pediment arrives factory-primed with a white acrylic primer. Installation requires level wall alignment, applying continuous polyurethane assembly adhesive on all back contact surfaces and miter joints, and mechanical screw anchoring. Fill countersunk screw heads and joint gaps with acrylic or facade putty, sand with 180-220 grit, and finish with paint.
