Mammoth Bafflestack helps to create comfortable internal environments by improving sound insulation between spaces.

Mammoth® Bafflestack insulation is a roll form product made from 100% thermally bonded polyester fibres, designed to be stacked and compressed within the plenum space above partition walls, to the roof or floor above. This reduces sound intensity and transference between rooms, without the need for the construction of walls within the plenum space

Mammoth’s acoustic range also includes Wall SectionsWall BlanketsPanel Absorber and Duct Liner Insulation.

* Calculations are based on 500ml PET Bottles (16.2g).
