Facade Column Capital
Polure facade column capitals deliver ornate exterior crowning for entrance pillars, porch colonnades, and building facade columns. Formed from high-density rigid polyurethane (150-220 kg/m³), these exterior facade capitals offer wood-like mechanical durability and sharp relief detailing without adding heavy dead loads to building walls. The closed-cell physical matrix features water absorption under 1%, guaranteeing protection against rot, swelling, mold, and freeze-thaw cracking outdoors. Fire resistance rated B2 and stable from -100 °C / +80 °C, each capital section is pre-primed with white acrylic primer. Installation is completed by applying continuous polyurethane assembly adhesive to contact faces, securing with mechanical screws, filling fastener holes with facade filler, sanding smooth with 180-220 grit, and painting with exterior paint.
