Column Cap Capital
Polure column cap capitals integrate capital ornamentation with top capping functionality for architectural columns, entryway pillars, and facade pilasters. Engineered from high-density rigid polyurethane (150-220 kg/m³), these architectural components match the mechanical durability of timber while offering lightweight overhead handling. Their closed-cell structure keeps water absorption under 1%, ensuring complete resistance to rot, swelling, mold, and weather exposure. Rated B2 for fire resistance and stable from -100 °C / +80 °C, every capital 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 topcoat paint.
Frequently Asked Questions
What material is used for Polure column cap capitals?
They are manufactured from high-density rigid polyurethane (150-220 kg/m³), providing wood-like durability and B2 fire rating.
Are column cap capitals load-bearing?
No, Polure column cap capitals are non-load-bearing decorative elements. Structural loads must be carried by an internal steel core profile.
How do you install column cap 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 cap capitals?
No, silicone is strictly forbidden as it lacks long-term bonding strength. Always use polyurethane assembly adhesive with mechanical screws.
