Exterior Column Cladding
Polure exterior column cladding transforms standard structural supports into architectural centerpieces on building facades and entrance porches. Formulated from high-density rigid polyurethane (150-220 kg/m³), this cladding provides robust impact resistance and weatherability matching natural stone or timber, without adding massive dead loads to building foundations. With a closed-cell structure boasting water absorption below 1%, it will never warp, rot, swell, or foster mold under harsh rain, freezing conditions, or high humidity. It operates reliably within temperature limits of -100 °C / +80 °C and meets Class B2 self-extinguishing flame standards. Pre-primed with a factory white acrylic coating, it requires painting with high-quality UV-resistant exterior paint. Installation requires continuous polyurethane assembly adhesive on wall contacts and joining seams, augmented by countersunk screws. Recessed screw heads and seams are filled, sanded using 180-220 grit, and finished.
Frequently Asked Questions
What material is Polure exterior column cladding made from?
Polure exterior column cladding is manufactured from high-density rigid polyurethane (150-220 kg/m³), offering stone-like durability, light weight, and Class B2 fire performance.
How does exterior column cladding withstand weather?
Its closed-cell structure keeps water absorption below 1%, preventing rot, freeze-thaw cracking, or warping between -100 °C / +80 °C.
How is exterior column cladding installed?
Apply continuous polyurethane assembly adhesive to contact faces and joints, then secure with mechanical screws. Silicone is forbidden. Fill joints, sand with 180-220 grit, and apply UV-resistant topcoat paint.
Is exterior column cladding load-bearing?
No, it is a hollow decorative cladding designed to surround load-bearing steel or concrete structural cores.
