Column Head Capital
Polure column head capitals combine classic capital molding details with solid upper column capping functionality. Formed from high-density rigid polyurethane (150-220 kg/m³), these column head components offer wood-like physical durability without adding structural weight. Closed-cell material density restricts water absorption under 1%, preventing rot, swelling, mold, and humidity damage across interior and exterior installations. Fire rated B2 and thermally stable between -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 filler, sanding smooth with 180-220 grit, and painting with topcoat paint.
Frequently Asked Questions
What material is used for Polure column head capitals?
They are manufactured from high-density rigid polyurethane (150-220 kg/m³), providing wood-like durability and B2 fire rating.
Are column head capitals load-bearing?
No, Polure column head capitals are non-load-bearing decorative elements. Structural loads must be carried by an internal steel core profile.
How do you install column head capitals?
Apply continuous PU assembly adhesive on contact edges, secure with mechanical screws, fill screw holes with filler, sand, and paint.
Is silicone allowed for mounting column head capitals?
No, silicone is strictly forbidden as it lacks long-term bonding strength. Always use polyurethane assembly adhesive with mechanical screws.
