Exterior Window Pediment Trim
The exterior window pediment trim by Polure introduces sharp classical architectural framing above windows and doorway entrances. Manufactured from high-density rigid polyurethane (150-220 kg/m³), it delivers wood-like mechanical strength and exceptional impact resistance, ensuring it will not dent during severe hail or storm exposure. Its closed-cell structure keeps water absorption under 1%, preventing rot, mold, swelling, or freeze-thaw splitting on exterior facades. Operating reliably across extreme temperature ranges from -100 °C / +80 °C, it carries a Class B2 fire safety rating. Delivered factory-primed with a smooth white acrylic technical coating, it requires finishing with elastic, UV-resistant exterior paints. Installation involves a clean, dry facade surface, continuous PU assembly adhesive applied along wall contact edges and joints, and countersunk mechanical screws. Fill screw holes with facade filler, sand smooth with 180-220 grit, and finish with quality topcoat.
