Exterior Decorative Lintel
Polure exterior decorative lintels provide classical horizontal headers, window lintel surrounds, and prominent entrance architraves for building facades. Manufactured from high-density rigid polyurethane (150-220 kg/m³), this architectural lintel delivers wood-like structural toughness and will not fracture or dent during heavy hail or severe storms. Featuring closed-cell waterproofing with less than 1% water absorption, it prevents water penetration, frost damage, swelling, and algae growth under outdoor weathering. Designed to perform reliably in temperatures from -100 °C / +80 °C with B2 fire safety compliance, every lintel comes factory-primed with a white acrylic technical primer. Installation requires level alignment, continuous polyurethane assembly adhesive on rear contact faces AND joining edges, and screw anchoring into mechanical plugs. Fill countersunk screw heads and joints with facade putty, sand smooth (180-220 grit), and finish with elastic exterior UV paint.
