Pillar Cap Polyurethane
Polure pillar caps in polyurethane provide durable architectural crowning and protective capping for decorative columns, entry pillars, and wall pilasters. Manufactured from high-density rigid polyurethane (150-220 kg/m³), these pillar caps deliver timber-like mechanical toughness without adding excessive structural dead weight overhead. Their closed-cell physical structure features water absorption under 1%, safeguarding against rot, swelling, mold, and freeze-thaw damage in humid interior rooms or on exterior building facades. Certified B2 for fire safety and stable from -100 °C / +80 °C, each capital section arrives pre-primed with white acrylic primer. Installation is completed by applying continuous polyurethane assembly adhesive to 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 caps?
They are manufactured from high-density rigid polyurethane (150-220 kg/m³), providing wood-like durability and B2 fire rating.
Are polyurethane pillar caps load-bearing?
No, Polure polyurethane pillar caps are non-load-bearing decorative elements. Structural loads must be carried by an internal steel core profile.
How do you install polyurethane pillar 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 pillar cap mounting?
No, silicone is strictly forbidden as it lacks long-term structural bonding. Always use polyurethane assembly adhesive with mechanical screws.
