Column Head Polyurethane
Polure polyurethane column heads provide elegant crowning and decorative framing for interior and exterior architectural columns. Engineered from high-density rigid polyurethane (150-220 kg/m³), these column heads deliver wood-like mechanical durability without adding heavy structural loads overhead. Their closed-cell structure keeps water absorption under 1%, ensuring complete resistance to rot, swelling, mold, and weather exposure outdoors. Rated B2 for fire resistance and stable from -100 °C / +80 °C, every column head 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 topcoat paint.
Frequently Asked Questions
What material is used for Polure polyurethane column heads?
They are manufactured from high-density rigid polyurethane (150-220 kg/m³), providing wood-like durability and B2 fire rating.
Are polyurethane column heads load-bearing?
No, Polure polyurethane column heads are non-load-bearing decorative elements. Structural loads must be carried by an internal steel core profile.
How do you install polyurethane column heads?
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 polyurethane column heads?
No, silicone is strictly forbidden as it lacks long-term bonding strength. Always use polyurethane assembly adhesive with mechanical screws.
