Polyurethane Pillar Capital
Polure polyurethane pillar capitals provide crisp architectural crowning and structural transition for decorative columns and wall pilasters. Formed from high-density rigid polyurethane (150-220 kg/m³), these capitals deliver wood-like durability and sharp relief detailing without introducing excessive weight to building structures. The closed-cell physical matrix features water absorption under 1%, providing long-term resistance to rain, humidity, freeze-thaw cycles, and mold on exterior facades or inside humid rooms. Rated B2 for fire safety and stable from -100 °C / +80 °C, each capital section is pre-primed with white acrylic primer. Installation is completed by applying continuous polyurethane assembly adhesive along contact edges, securing with mechanical screws, filling 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 pillar capitals?
They are manufactured from high-density rigid polyurethane (150-220 kg/m³), offering wood-like durability and B2 fire rating.
Are polyurethane pillar capitals load-bearing?
No, Polure polyurethane pillar capitals are non-load-bearing decorative elements. Structural loads must be carried by an internal steel core profile.
How do you install polyurethane pillar capitals?
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 pillar capital installation?
No, silicone is strictly forbidden as it lacks long-term structural bonding. Always use polyurethane assembly adhesive with mechanical screws.
