Exterior Cornice Moulding
Polure exterior cornice moulding brings bold architectural grandeur and weather-resistant elegance to roof overhangs, facade parapets, and exterior wall junctions. Crafted from high-density rigid polyurethane (150-220 kg/m³), this exterior moulding offers real wood-like impact strength without susceptible vulnerabilities such as rot, warping, or insect infestation. Its closed-cell composition ensures water absorption stays below 1%, shielding exterior walls against heavy rainfall, ice formation, and thermal expansion. Certified B2 for flame resistance and rated for outdoor temperatures ranging from -100 °C / +80 °C, it remains dimensionally stable in all seasons. Delivered with a factory white acrylic primer coat, installation requires dry facade surfaces, precise 45-degree miter cuts with a fine saw, a continuous bead of PU assembly adhesive along all contact edges, and mandatory mechanical fastening with countersunk screws. Fill screw points with facade filler, sand smooth with 180-220 grit paper, and finish with elastic UV-resistant exterior paint.
Frequently Asked Questions
What density material is used for Polure exterior cornice moulding?
Polure exterior cornice moulding is manufactured from high-density rigid polyurethane (150-220 kg/m³).
How does exterior cornice moulding perform in freezing temperatures?
With water absorption under 1% and thermal stability from -100 °C / +80 °C, it will not crack, split, or warp in freezing conditions.
Is mechanical screw fixing required for exterior cornice moulding?
Yes, installation requires a dual fastening system comprising continuous PU assembly adhesive and countersunk screws. Silicone is forbidden.
What type of paint is recommended for exterior cornice moulding?
Outdoor installations must be painted over the factory acrylic primer with an elastic, UV-resistant exterior facade paint.
