Column Head Model
Polure column head models offer a diverse selection of decorative upper column crowning profiles for classical and modern architectural projects. Molded from high-density rigid polyurethane (150-220 kg/m³), these models provide timber-like physical strength and crisp relief without adding heavy overhead dead load to walls. The closed-cell material matrix keeps water absorption under 1%, safeguarding the installation from rot, swelling, mold, and weather breakdown. Certified B2 fire resistant and thermally stable from -100 °C / +80 °C, each column head model is 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 column head models?
They are manufactured from high-density rigid polyurethane (150-220 kg/m³), providing wood-like durability and B2 fire rating.
Are column head models load-bearing?
No, Polure column head models are non-load-bearing decorative elements. Structural loads must be carried by an internal steel core profile.
How do you install column head models?
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 models?
No, silicone is strictly forbidden as it lacks long-term bonding strength. Always use polyurethane assembly adhesive with mechanical screws.
