Polyurethane Pillar Head
Polure polyurethane pillar heads deliver crisp structural capitals and ornamental crowns for wall pilasters and porch pillars. Formed from high-density rigid polyurethane (150-220 kg/m³), these architectural capitals combine wood-like mechanical durability with a light overall weight. The closed-cell material features water absorption under 1%, making it completely resistant to rain, humidity, mold, and rot. Fire class B2 certified and stable between -100 °C / +80 °C, each piece arrives pre-primed with white acrylic primer. Installation is completed by applying continuous polyurethane assembly adhesive to rear contact surfaces, securing with countersunk mechanical screws, filling fastener holes with facade filler, sanding smooth with 180-220 grit, and painting with quality topcoat paint.
Frequently Asked Questions
What material is used for Polure polyurethane pillar heads?
They are manufactured from high-density rigid polyurethane (150-220 kg/m³), providing wood-like strength and B2 fire rating.
Are polyurethane pillar heads load-bearing?
No, they are decorative non-load-bearing elements. Structural loads must be supported by an internal steel core profile.
How do you install polyurethane pillar heads?
Apply continuous PU assembly adhesive to contact faces, secure with mechanical screws, fill screw holes with filler, sand, and paint.
Can silicone adhesive be used for polyurethane pillar heads?
No, silicone is strictly forbidden as it lacks long-term structural bonding. Always use polyurethane assembly adhesive together with mechanical screws.
