Arched Door Pediment
Polure arched door pediments provide classical curved pediments and grand entryway headers over exterior front doors and interior portals. Manufactured from high-density rigid polyurethane (150-220 kg/m³), this arched header delivers timber-like impact strength while eliminating excess weight on door frames. Featuring closed-cell waterproofing with under 1% water absorption, it will not rot, warp, swell, or cultivate mold in humid foyer environments or exposed exterior entrances. Operating reliably within temperatures from -100 °C / +80 °C and certified B2 for fire safety, every pediment arrives factory-coated with a white technical acrylic primer. Installation requires level positioning, continuous polyurethane assembly adhesive on rear contact faces AND joining edges, and mechanical screw attachment into countersunk anchors. Fill screw holes and joints with acrylic or facade putty, sand smooth with 180-220 grit, and finish with paint.
