Technical CAD details showing acoustic insulation assemblies for dry partitions and traditional masonry walls. The drawings include cross-sections of various wall systems designed to reduce airborne noise and improve sound absorption across different frequencies.
Specific details cover dry wall construction using 46 mm galvanized steel profiles, rock wool panels (70 kg/m3 density), and bilayer insulation. The assemblies feature multiple layers of 13 mm gypsum plasterboard and acoustic membranes (M.A.D.). Traditional masonry details include existing plastered walls with added insulation layers and new brick partitions. Key components shown include Rocdan rock wool and Acustidan bilayer insulation. The file includes an acoustic sandwich detail illustrating the integration of membranes between plaster panels for low-frequency performance.
The drawings also specify assembly methods such as mechanical fixing with screws, the use of contact glue for membranes, and joint sealing. These details are applicable for soundproofing median walls and interior partitions requiring high levels of acoustic isolation. Aislamiento acústico de paredes.
