Exterior Architectural Support
Polure exterior architectural supports provide decorative bracket elements engineered for roof eave overhangs, window ledges, balcony undersides, and facade projections. Molded from high-density rigid polyurethane (150-220 kg/m³), these supports replicate heavy timber corbels and carved stone brackets with exceptional mechanical strength and light weight. Their closed-cell structure keeps water absorption under 1%, preventing rot, swelling, mold, and frost damage in severe outdoor climates. Rated B2 for self-extinguishing fire safety, they withstand thermal ranges from -100 °C / +80 °C without distortion. Factory-primed in white acrylic paint, they must be painted outdoors with UV-resistant exterior paints. Installation requires continuous polyurethane assembly adhesive on all contact edges alongside countersunk mechanical screws.
Frequently Asked Questions
What material is used for Polure exterior architectural supports?
They are molded from high-density rigid polyurethane (150-220 kg/m³), offering wood-like strength and Class B2 fire safety.
Are exterior architectural supports fully weatherproof?
Yes, water absorption under 1% and thermal resistance from -100 °C / +80 °C ensure complete weather and frost resistance.
How are exterior architectural supports installed?
Apply continuous polyurethane assembly adhesive on contact faces and secure with countersunk mechanical screws. Silicone is forbidden.
Do exterior architectural supports need to be painted?
Yes, for exterior use, they must be painted with elastic UV-resistant facade paint to prevent UV fading.
