High Density Column Capital
Polure high density column capitals engineered from rigid polyurethane (150-220 kg/m³) combine classic architectural grandeur with state-of-the-art polymer durability. Built to withstand high-impact physical forces without chipping, denting, or cracking, these capitals provide a wood-equivalent structural texture at a fraction of the weight. Their closed-cell structural body resists water absorption below 1%, making them completely impervious to rot, swelling, and fungal decay in humid interior or outdoor facade settings. Resistant to temperature shifts from -100 °C / +80 °C and certified B2 for fire safety, they arrive factory pre-primed with a white acrylic coating. Installation is completed using a dual system of polyurethane assembly adhesive and countersunk screws.
Frequently Asked Questions
What density material is used in Polure high density column capitals?
Polure high density column capitals are manufactured from rigid polyurethane with a high density of 150-220 kg/m³ (production target ~160 kg/m³), providing superior impact resistance.
Are high density column capitals structural or load-bearing?
No, high density column capitals are non-load-bearing decorative components. Load-bearing requirements must be supported by an internal structural pillar.
Can high density column capitals be installed outdoors?
Yes. With a closed-cell matrix and water absorption below 1%, they withstand severe weather between -100 °C / +80 °C when painted with exterior UV paint.
How are high density column capitals installed?
Apply continuous PU assembly adhesive to all contact edges and secure with countersunk mechanical screws. Fill screw heads with acrylic putty, sand smooth, and paint.
Is silicone adhesive permitted for mounting high density column capitals?
No, silicone is strictly forbidden as it cannot support structural adhesion. Always use polyurethane assembly adhesive and screws.
