Exterior Column Head
Polure exterior column head provides a weather-hardened, elegant capital crowning exterior pillars and entrance porticos. Engineered from high-density rigid polyurethane (150-220 kg/m³), this capital delivers wood-like mechanical resistance while staying light enough for secure overhead positioning. Closed-cell geometry maintains water absorption under 1%, preventing rain penetration, rot, mold growth, and freeze-thaw damage. Stable under severe climate conditions from -100 °C / +80 °C, it complies with B2 fire safety standards. Supplied with a factory white acrylic technical primer, installation uses continuous PU assembly adhesive on contact edges paired with mechanical countersunk screws. Fill joint lines and screw holes with facade filler, sand smooth with 180-220 grit paper, and finish with durable exterior UV paint.
Frequently Asked Questions
What material is used in Polure exterior column head?
Polure exterior column head is manufactured from high-density rigid polyurethane (150-220 kg/m³), combining weather resilience with light weight.
How do you install Polure exterior column head on facades?
Apply continuous polyurethane assembly adhesive to mounting edges and secure with countersunk mechanical screws. Silicone adhesive is forbidden.
Does Polure exterior column head resist freeze-thaw cycles?
Yes. Water absorption is under 1% and thermal stability ranges from -100 °C / +80 °C, preventing cracking or swelling in frost.
What paint is best for exterior column heads?
Lightly sand factory white primer with 180-220 grit sandpaper, then apply two coats of high-grade UV-resistant outdoor facade paint.
Is Polure exterior column head load-bearing?
No, it is a decorative hollow capital. Structural loads must be supported independently by internal steel posts.
