Rigid PU Arch Profile
Polure rigid PU arch profiles frame interior door arches, passageways, and curved wall openings with architectural precision. Formed from high-density rigid polyurethane (150-220 kg/m³), these pre-curved arch moldings deliver wood-like durability with zero risk of cracking or warping. Their non-porous closed-cell material restricts water absorption to under 1%, ensuring full resistance to humidity, rot, and mold growth. Certified B2 for fire safety and thermally stable from -100 °C / +80 °C, all arch profiles come factory-primed with white acrylic primer ready for final topcoat painting. Installation requires miter joints, continuous PU assembly adhesive on all contact edges, and mechanical countersunk screw anchoring.
