ROCKWOOL® Acoustic Infills
Sound-absorbing trough fillers for perforated steel decks. The underside of an exposed profiled deck is acoustically reflective, which serves to increase reverberant noise in the space below, making for a noisy and echoey acoustic environment. The solution is to install ROCKWOOL Acoustic Infills into the troughs of a perforated deck. This tissue-faced product acts to absorb incident sound, reducing noise build-up, which lowers the reverberation time and creates a quieter acoustic environment.
ROCKWOOL Acoustic Infills are specially engineered into trapezoidal shapes that can be suited to fit all types of perforated metal roof deck profiles. Ideal for use in flat roof areas such as over convention and sports halls, manufacturing plants, or corridors, this product has an optimised density to absorb sound. Acoustic Infills have been designed and tested for use with ROCKWOOL HARDROCK® as a solution to parts E3 and E4 of Approved Document E, as well as BB93, achieving Class C sound absorption in accordance with BS EN ISO 11654.
