Exterior Facade Bracket
Polure exterior facade brackets provide classic architectural relief and structural ornament underneath roof eaves, balconies, porticos, and window projections. Manufactured from high-density rigid polyurethane (150-220 kg/m³), these facade corbels possess wood-like mechanical durability while remaining lightweight to prevent adding structural strain to exterior wall substrates. Their closed-cell structure maintains water absorption below 1%, ensuring absolute resistance to heavy rain, frost, swelling, rotting, and pest damage on outdoor building fronts. Rated B2 for fire safety, they withstand extreme weather temperatures ranging from -100 °C / +80 °C without shrinkage or distortion. Pre-primed at the factory with a white acrylic coating, they accept exterior paints smoothly. Installation requires cleaning the mounting substrate, applying a continuous bead of PU assembly adhesive along contact surfaces, securing with countersunk screws, filling fastener holes with exterior filler, and painting with UV-resistant exterior paint.
Frequently Asked Questions
What material is Polure exterior facade bracket made of?
Polure exterior facade bracket is made of high-density rigid polyurethane (150-220 kg/m³), providing strong impact resistance, crisp carved detail, and a B2 fire safety rating.
Will exterior facade brackets withstand harsh outdoor weather and rain?
Yes. With water absorption under 1% and thermal resistance from -100 °C / +80 °C, they will not absorb water, rot, warp, or freeze-crack outdoors.
How are exterior facade brackets securely mounted to building walls?
Installation requires applying continuous polyurethane assembly adhesive on all contact edges and securing the bracket mechanically with countersunk screws.
Is silicone adhesive permitted when installing exterior facade brackets?
No, silicone adhesive is strictly prohibited because it lacks structural bonding strength. Polyurethane assembly adhesive along with mechanical screws must be used.
