Sound becomes noise when it disturbs. Isocell cellulose keeps the noise outside (or inside).
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)
