The proposed solution is realized with galvanized single steel frame with increased thickness 08/10, 12/10 and 20/10mm or what result from static calculations, distanced 400mm with external vertical profile double.

Inside every MODULO JJ it’s inserted in factory the mineral wool insulation material for best thermal-acoustic performances; the module it’s closed on external sides with fiber cement boards which gives very high mechanical resistance features.

Every module has an “interpenetration system” for fastening to adjacent module with special screws VT4.0*32, galvanized and self-tapping; the fastening to existent wall is variable and to be specifically considered every time.
