Exterior Window Architraves
Polure exterior window architraves provide weather-resistant, architecturally detailed trim moldings engineered to frame outdoor window surrounds and facade openings. Molded from high-density rigid polyurethane (150-220 kg/m³), these exterior architraves deliver wood-like durability and hail resistance without rotting, warping, or cracking. Featuring a closed-cell polymer structure with water absorption under 1%, they will never absorb rainwater or cultivate mold under severe freeze-thaw cycles. Operating reliably across temperatures from -100 °C / +80 °C with Class B2 fire safety certification, each architrave comes pre-coated with factory white acrylic primer. Installation requires applying continuous polyurethane assembly adhesive on rear contact faces and mitred joints (silicone is strictly forbidden), secured with mechanical screws. Fill screw recesses with facade filler, sand smooth with 180-220 grit paper, and coat with elastic, UV-resistant exterior paint.
