Unlike traditional mineral wool insulation, Cellecta’s FIBREfon Micro 50 sound proofing rolls are manufactured from unique polyester fibres, making them soft to touch and easy to install. The unique fibres deliver superior sound absorbing properties, with 50mm FIBREfon Micro 50 offering equivalent acoustic performance to a traditional 100mm mineral wool. FIBREfon Micro 50 is Suitable for installation between timber floor joists and in wall cavities of refurbishment and new build developments.
