Concept Acoustic Infills are designed to prevent reverberation and improve the acoustic environment in buildings with large areas of hard internal surfaces such as leisure centres, school sports halls and other acoustically sensitive buildings such as film and sound studios.

Concept Acoustic Infills are normally supplied 1200mm long and are factory cut to fit the relevant roof profile. Shorter lengths are available on request.

The product can be supplied un-faced although where it is used with perforated metal decks, it is normally faced on the lower three sides with black or white glass tissue. Alternatively, it can be faced on all four sides to further decrease the risk of fibre migration.

Concept Acoustic Infills are available in the following grades :

The mineral wool core of a Trapezoidal Acoustic Infill achieves a fire classification of Euroclass A1 as defined in BS EN 13501-1.

The use of Concept Acoustic Infills can contribute towards the satisfaction of a requirement for a ceiling with Class C acoustic absorption. See Approved Document E and Building Bulletin 93 (The Acoustic Design of Schools) for guidance.

Concept Acoustic Infills are normally supplied on polyethylene wrapped pallets with weather protective hoods.

The Infills are installed directly into the upper trough of the profiled roofing sheet. All joints should be tightly butted and, where necessary, lengths can be trimmed using a sharp knife or a finely serrated saw.
