Classical Frame Corner
Polure classical frame corners deliver pre-molded right-angle junction motifs designed to terminate wall panelling frames with classic architectural proportion. Molded from high-density rigid polyurethane (150-220 kg/m³), these pieces provide timber-like impact resistance without splitting, splintering, or sagging. Closed-cell polyurethane restricts water absorption below 1%, making them suitable for high-humidity environments like master bathrooms and kitchens without rot or swelling. Certified Class B2 for fire safety and dimensionally stable between -100 °C / +80 °C, the smooth profile stays crisp. Pre-primed with white acrylic primer, indoor fitting requires continuous polyurethane assembly adhesive and mechanical screws.
