Polyurethane Column Capital
The Polure polyurethane column capital crown adds essential classical proportion and sculptural grace to interior columns and exterior building facades. Engineered from high-density rigid polyurethane (150-220 kg/m³), this lightweight architectural element offers wood-like mechanical durability while avoiding structural weight overload. Its closed-cell structure maintains water absorption below 1%, rendering it completely immune to rotting, swelling, warping, and mold in humid environments or rain. With operational temperature resilience spanning -100 °C / +80 °C and B2 fire retardancy, each unit is delivered pre-coated with a white acrylic technical primer. Securing the capital involves applying a continuous line of polyurethane assembly adhesive across contact edges and locking with mechanical screws. Fill countersunk screw heads and joint gaps with acrylic filler, sand smooth using 180-220 grit paper, and finish with quality topcoat paint.
