SOUNDMIX 340 GA is a complex made up of a sheet of synthetic EPDM rubber, of 3.5 kg/m2, which has a sheet of 4mm-thick high-density reticulated polyethylene adhered to one side of it. The complex also has a fleece on the rubber side.
SOUNDMIX GA between the framework of a concrete flooring block (25 + 5 cm) and a 6 cm thick layer of cement on top finished off with ceramic tiles gives the following results in acoustic reduction:
|Rw (C; Ctr)||= 60 (-2; -6)||dB ISO 717-1 to airborne noise|
|R (A)||= 59 dB(A)||NBE CA-88 to airborne noise|
|Ln,w (Ci)||= 54 (0)||dB ISO 717-2 to impact noise|
|Ln(A)||= 60.3 dB(A)||NBE CA-88 to impact noise|
