Half Column Head
Polure half column head (pilaster capital) delivers a refined top termination designed specifically for half-round decorative columns and wall pilasters. Molded from high-density rigid polyurethane (150-220 kg/m³), this architectural capital boasts wood-like toughness and sharp detail retention without adding structural weight. Its closed-cell composition ensures water absorption stays below 1%, protecting against dampness, swelling, rot, or mold growth in high-humidity zones and outdoor installations. Capable of enduring temperatures from -100 °C / +80 °C, it meets Class B2 self-extinguishing flame specifications. Supplied factory-primed in white acrylic paint, it is ready for water-based or synthetic topcoats. Installation calls for continuous polyurethane assembly adhesive across contact surfaces and mechanical countersunk screws. Conceal screw heads and joints with acrylic filler, sand with 180-220 grit, and finish with paint.
