External wall with Jendy Joss® thermal-acoustic high-performance dry system MODULO_JJ, with “preassembled” in factory module, designed and custom-made.
The wall has a total thickness of 237mm (excluded external finishing), if possible, it must be applied externally to the structural line for eliminate the thermal bridging and it is ready for shaving and painting, coating or the ventilated facade, it has linear thermal transmittance U=0.168 W/mqK, periodic thermal transmittance Yi.e=0.075 W/mqK and thermal attenuation factor 0.446. The module are composed of a galvanized steel frame with horizontal and vertical profiles type S280GD, different sections, thickness 12/10mm and 20/10mm, width 170mm, distance between vertical 600mm, conveniently assembled, features suitable holes for fixing and assembly. The base profiles are isolated with a 3 mm waterproof polyethylene sheath with acoustic and waterproof function. To close the steel frame of each MODULO_JJ there are two calcium silicate boards UR12 with thickness 12mm, screwed to the metal by special screws VT4.2*32, galvanized and self-tapping.
Inside every module there is a rockwool panel with thickness 160mm and density 70 kg/m³ for thermal and acoustic insulation, with aluminum vapor barrier inside. All UR calciosilicate boards have a high density of 1,200 kg/m³ and high mechanical performance, in A1 Fire Class Reaction, with universal use, with absolutely no harmful materials and have a very low Radioactivity Index of 0.15. Every module has an “interpenetration system” for fastening to adjacent module with special screws VT4.2*32, galvanized and self-tapping. The interior surface will be covered with 13 mm plasterboard coupled with 30mm rockwool panel with 85 kg/m³ density, glued to the UR boards for eliminate the steel thermal bridging. The surface of plasterboard will be finished with a traditional joints shaving to obtain a surface ready for sanding and painting. For the external surface, in the case of shaving and painting, the 4mm external joints between the UR12 calciumsilicate boards will be filled with specifical product and inside fiberglass net of 165 gr/mq and width 5 cm. In case of ventilated facade it will be applied a 110 gr/mq black vapor barrier with waterproof function also during the construction time and dark background in case of facade with opened joints. Including thermal bridging treatments.
