Polyurethane Column Cap
Polure polyurethane column caps provide elegant crowning and protective top framing for interior and exterior architectural columns. Engineered from high-density rigid polyurethane (150-220 kg/m³), these caps deliver wood-like durability without the danger of rot, splitting, or insect damage. Closed-cell physical matrix keeps water absorption under 1%, preserving crisp surface detailing through severe humidity, rain, and thermal swings from -100 °C / +80 °C. Certified B2 fire safe, every column cap comes factory 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 polyurethane column caps?
They are manufactured from high-density rigid polyurethane (150-220 kg/m³), providing wood-like durability and B2 fire rating.
Are polyurethane column caps load-bearing?
No, Polure polyurethane column caps are non-load-bearing decorative elements. Structural loads must be carried by an internal steel core profile.
How do you install polyurethane column caps?
Apply continuous PU assembly adhesive on contact edges, secure with mechanical screws, fill screw holes with filler, sand, and paint.
Is silicone permitted for polyurethane column cap mounting?
No, silicone is strictly forbidden as it lacks long-term structural bonding. Always use polyurethane assembly adhesive with mechanical screws.
