Aluben™ is a composite panel made with a honeycomb core in polycarbonate and two aluminum layers of 5 to 10 mm thick. This construction is very light-weight. The aluminium layers are treated with a primer for polyurethane adhesives. Aluben™ is used to support high-quality materials such as thin marble, granite, stone, wood or other thin cladding material to get stiffness and stability without increasing the load. The composite panel can be used as a structural element for risen-floors to support floor claddings and under-layers or insulating materials. Thanks to its low flame-spread characteristic (RINA certificate), Aluben™ can also be used to build floors and inner bulkheads for yachts and boats.
