Exterior Pilaster Header
Polure exterior pilaster header creates a distinguished crowning element for flat wall pilasters on exterior building elevations and entrance portals. Manufactured from high-density rigid polyurethane (150-220 kg/m³), this exterior decorative capital header delivers wood-like mechanical durability while remaining lightweight to prevent wall stress. Featuring a closed-cell composition with water absorption under 1%, it resists rot, mold, swelling, and severe weather exposure across temperatures from -100 °C / +80 °C. Rated Class B2 for self-extinguishing flame resistance, it is pre-coated with factory white acrylic technical primer. Installation requires continuous polyurethane assembly adhesive on wall contact surfaces and mitered joints, paired with countersunk mechanical screws. Fill joints and screw holes with exterior acrylic putty, sand smooth with 180-220 grit paper, and finish with UV-resistant exterior paint.
