Waterproof Column Crown
Polure waterproof column crowns top indoor and exterior columns with ornate architectural molding completely immune to water damage. Crafted from high-density rigid polyurethane (150-220 kg/m³), each capital delivers wood-like mechanical toughness without adding structural weight. Closed-cell physical properties maintain water absorption below 1%, ensuring the crown will not rot, swell, or deteriorate under heavy rain or frost. Engineered to resist temperature variations from -100 °C / +80 °C and rated B2 for fire safety, the crown arrives factory pre-primed in technical white acrylic primer. Installation is completed using continuous polyurethane assembly adhesive paired with countersunk mechanical screws.
Frequently Asked Questions
What material is used to manufacture the waterproof column crown?
It is made of high-density rigid polyurethane (150-220 kg/m³), providing wood-like impact strength and light weight.
Is the waterproof column crown resistant to frost and humidity?
Yes, water absorption under 1% and thermal stability between -100 °C / +80 °C ensure full exterior weather resistance.
Can the waterproof column crown support structural loads?
No, Polure crowns are decorative and non-load-bearing. Structural loads must be carried by an internal steel core.
How is the waterproof column crown installed outdoors?
Installation requires continuous polyurethane assembly adhesive on joints and mechanical screw anchoring.
