Sandwich type acoustic composite panel manufacturing and assembling method for realization of insulating roof of e.g. veranda, involves disposing facing against face of composite panel turned towards interior of space to be protected
The method involves producing a sandwich of an elastic core (3) and two rigid insulating cores (2), where the elastic core is interposed between the insulating cores and has strong elasticity with a complex young modulus. An external rigid facing (1) of a sandwich type acoustic composite panel is disposed against a face of a composite sandwich type acoustic composite panel turned towards an interior of space to be protected. The cores are made of organic material such as insulating foam of polystyrene, polyurethane, melamine, PVC and elastomer, or mineral e.g. metal of glass and rock.
