NATURALLY BETTER SOUND INSULATION
Isocell cellulose achieves up to 7 dB for dividing walls and up to 5 dB better sound insulation values for dividing ceilings than found with conventional fibre mats.
Due alone to the fact that cavities are filled without gaps, a better sound insulation level than in the case of mat-form insulation is to be assumed. Incidentally, this was confirmed by TGM Vienna with a comparative test. (Test No. VA AB 11961)
Sound propagates in waves through the air. The sound volume is measured in decibels, dB. A normal entertainment is indicated as 40-50 dB, a heavily used road as 80 dB and a compressed air hammer as approx. 100 dB. The pain threshold is 134 dB.
