Interior Double Wall with Jendy Joss® acoustic high-performance dry system compose of a galvanized steel frame, calcium-silicate boards and mineral wool panel with total thickness ≥222mm, ready for sanding and painting. The steel frame is made of a double galvanized profiles type DX51 thickness 08/10mm, section 50-75-50mm, with distance of 600mm and inserted into upper and lower profiles of section 40-75-40mm. The base profiles are isolated from the existing structures with a 3 mm waterproof polyethylene sheath with acoustic and waterproof function. To close the steel frame and inside there are three calcium silicate boards UR12 with thickness 12mm, screwed to the metal by special screws VT4.2*32, galvanized and self-tapping. All UR calciumsilicate 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. Inside every steel frame there is a 70mm mineral wool panel for acoustic insulation.
Up to UR12 surface will be applied a 13mm plasterboard screwed by galvanized VT3.5*25 directly on calcium-silicate boards and completed with a traditional joints shaving to obtain a surface ready for sanding and painting.
