A new, efficient, economic, stylish and sustainable construction solution for re-covering building façades that are made up of 2 aluminium sheets joined by a nucleus of thermoplastic resins. A composite panel comprising of an external layer of aluminium alloy triple coated with PvdF paint (polyvinyl flouride) that offers great resistance to corrosion and ageing. The internal nucleus is made up of thermoplastic resins (polyethelene).This material union provides the composite panel with some excellent mechanical properties: high impact resistance, increased rigidity and reduced weight. It is a product designed and tested to intgrate in to buildings with increased thermal and accoustic features.The composite panel is also available with the fire retardant option denominated FR (Fire Retardancy), that guarantees answers with respect to hypothetical fires. It is a 4 mm mm panel made up of 0.5 mm thick aluminium sheets, coated with PvdF paint with a thickness of 25/35 microns on the external face and a central nucleus consisting of a mineral composition and 3 mm thick polyethelene.
