Exterior Corbel
Polure exterior corbels add imposing architectural detail and classic support styling to exterior eaves, window surrounds, balcony overhangs, and porticos. Engineered from high-density rigid polyurethane (150-220 kg/m³), these exterior brackets deliver wood- and stone-like impact resistance without structural weight. Thanks to a closed-cell polymer structure with water absorption under 1%, they offer 100% resistance against rain, frost, rot, and UV weathering. Operating reliably from -100 °C / +80 °C and rated B2 for fire safety, each corbel carries a factory-applied white acrylic technical primer. Installation is completed by applying continuous polyurethane assembly adhesive to rear contact surfaces and securing with mechanical screws. Screw heads are filled with exterior putty, sanded smooth, and painted.
Frequently Asked Questions
What density material is used for Polure exterior corbels?
They are molded from high-density rigid polyurethane (150-220 kg/m³), delivering high structural durability at a lightweight handle.
Are Polure exterior corbels load-bearing?
No, Polure exterior corbels are decorative architectural brackets and strictly non-load-bearing.
Do Polure exterior corbels withstand frost and extreme outdoor weather?
Yes. With water absorption under 1%, they endure temperatures from -100 °C / +80 °C without cracking, rotting, or swelling.
How are exterior corbels attached to building facades?
Apply continuous polyurethane assembly adhesive to contact faces and secure with mechanical countersunk screws. Fill screw holes with facade filler, sand, and paint. Silicone is forbidden.
What paint finish is required for exterior corbels?
Corbels come factory-primed with white acrylic primer and must be topcoated with an elastic, UV-resistant exterior facade paint.
