A 1960’s former office building at Gatwick Airport’s south terminal has been completely stripped out and converted into a new five storey 245 bedroom BLOC hotel.
Among the high specifications demanded by the client were extremely good levels of sound insulation for a pleasant quiet environment for its guests, particularly important at a busy international airport. In addition, varying floor heights had to be achieved, to an exacting accuracy, throughout the building.
To meet these requirements InstaCoustic’s cradle and batten high quality adjustable acoustic flooring was specified for all rooms and corridors over the four upper floors.
The recycled rubber crumb cradles were set out and the system was laser-levelled to ensure a completely level finished floor height. The battens were placed in position and acoustic insulation quilt laid between them. The 18mm chipboard was fixed to the battens and, to further assist the acoustic performance, InstaLay, our rubber crumb acoustic underlay, was installed over the chipboard.
To comply with stringent fire safety requirements, fire resistant Intubatts were also installed in the floor void at room thresholds and corridor fire doors to help prevent fire spreading.
