Decorative Door Arch
Polure decorative door arches frame grand residential entryways and interior portals with classical curved molding and sophisticated shadow lines. Manufactured from high-density rigid polyurethane (150-220 kg/m³), this entrance surround delivers timber-like mechanical strength and impact resistance while remaining lightweight to eliminate structural wall stress. Featuring closed-cell composition with under 1% water absorption, it will not rot, warp, swell, or cultivate mold on exposed exterior portals or in humid interior spaces. Formulated to perform across temperatures from -100 °C / +80 °C and rated B2 for fire safety, every arch comes factory-primed with a white technical acrylic primer. Installation requires level alignment, 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.
