Exterior Architectural Moulding
Polure exterior architectural moulding enhances building facades, window surrounds, and door frames with sharp detail and lasting weather resistance. Formulated from high-density rigid polyurethane (150-220 kg/m³), this moulding delivers wood-like impact strength while remaining lightweight to simplify installation. Closed-cell composition restricts water absorption to under 1%, guaranteeing long-term resistance to rain, frost, rot, mold, and insect infestation. Capable of enduring temperatures from -100 °C / +80 °C, it holds a self-extinguishing B2 fire safety classification. Pre-treated with factory white acrylic technical primer, mounting requires continuous PU assembly adhesive on contact faces combined with mechanical countersunk screws. Fill screw holes and joint lines with exterior filler, sand with 180-220 grit paper, and apply exterior topcoat paint.
