the measurement and evaluation in the laboratory of the sound insulation of buildings and their elements.
The test was carried out on 125 mm thick walls – double stratigraphy of plasterboard – 75 mm structure with 70 mm rock wool for the 125 double slab plasterboard, for achieve an overall sound insulation performance of:
• Rw=39 dB (-1;-4) for wall thickness 125 mm
• Rw=32 dB (-1;-2) for wall thickness 125 mm
Calculated on the area of the headwall 10.73 m².
Panel thickness 43 mm for finished 125 mm wall,
made with wooden perimeter frame and soundproofing material (for 39 dB version) that
has different layers, plated with 4 mm MDF.
