Historical Restoration Column
Polure historical restoration columns replicate authentic period column detail for historic building renovations, heritage facades, and classical indoor spaces. Manufactured from high-density rigid polyurethane (150-220 kg/m³), these architectural columns combine wood-like surface detail and impact strength without putting heavy dead load on historic substrates. The closed-cell material features water absorption under 1%, protecting heritage projects from rotting, swelling, and mold growth. Certified fire class B2 and stable from -100 °C / +80 °C, each column section comes pre-primed with white acrylic primer. Installation is completed by applying continuous polyurethane assembly adhesive to contact faces and joining seams, securing with mechanical screws, filling joint lines with facade filler, sanding smooth with 180-220 grit, and painting with suitable topcoat paint.
