Acoustic insulation 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® roof systems as a solution to E3 and E4 of the Approved Document E, achieving Class C sound absorption in accordance with BS EN ISO 11654. ACOUSTIC INFILLS An effective solution to control the indoor acoustic environment. ROCKWOOL Acoustic Infills are engineered to fit within the troughs of a perforated metal deck, where they act to absorb incident sound that would otherwise be reflected back into the space below. This lowers the reverberation time within the room, which lowers the noise level and can improve speech intelligibility.
