Exterior Polyurethane Pilaster Head
Polure exterior polyurethane pilaster heads deliver classical architectural elegance, grand entrance framing, and sophisticated facade crowning for residential and commercial building exteriors. Precision-molded using high-density rigid polyurethane (150-220 kg/m³), these pilaster capitals capture sharp classical relief while remaining exceptionally lightweight for secure wall-mounting. Featuring a closed-cell matrix, water absorption is strictly under 1%, ensuring the pilaster heads will never rot, swell, warp, or crack under freeze-thaw cycles or extreme weather (-100 °C / +80 °C). Rated B2 for fire safety, each head arrives pre-treated with a protective white acrylic primer coat. Note that these pilaster heads are purely decorative and non-load-bearing. Installation requires continuous polyurethane assembly adhesive paired with mechanical countersunk screws. Fill screw holes with facade putty, sand smooth, and finish with elastic UV-resistant exterior paint.
