Decorative Exterior Trim
Polure decorative exterior trim profiles add sophisticated architectural framing to outdoor windows, doors, and facade transitions. Molded from high-density rigid polyurethane (150-220 kg/m³), these exterior mouldings possess structural impact resistance to withstand severe weather, including hail and freezing cycles without denting. Closed-cell polyurethane maintains water absorption below 1%, protecting the trim from rot, moisture expansion, and fungal decay. Certified Class B2 for fire safety and thermally stable between -100 °C / +80 °C, the crisp decorative detail withstands thermal stress. Pre-primed with white acrylic primer, outdoor installation requires continuous polyurethane assembly adhesive, mechanical screws, and protective UV-resistant exterior topcoat paint.
