Acoustic flooring with integral underfloor heating used at major new London development

At Holland Green, a prestige residential development in West London, all apartments have been fitted with InstaCoustic’s quality acoustic flooring combined with an integral, high performance underfloor heating system.

Designed by OMA Architects for developers Chelsfield, the three buildings, ranging from seven to nine storeys, are grouped around the former Commonwealth Institute exhibition hall, which is the proposed new home of the Design Museum. Just north of Kensington High Street, the Holland Green development is also adjacent to Holland Park.

Throughout the 56 apartments, InstaCoustic installed over 11,000m² of its adjustable C40 cradle and batten system, which was laser-levelled on site and produced a 5dB improvement over the acoustic requirements of Building Regulations. The underfloor heating’s foil-faced panels, containing the heating pipes, fit between the floor’s rubber crumb cradles, suspended on special acoustic rails. These ensure 100% contact with the floor board to produce more controllable and highly efficient thermal conductivity.


Additional benefits of the System include:

  • Removes the need for concrete screeds
  • No concrete drying times or contract delays
  • Reduced building weight and lorry movements
  • High thermal conductivity and fast heating response times
  • Low water temperatures and greater control save energy


InstaCoustic was specified due to the excellent performance of its efficient integrated system and its complete supply and fit service, which reduced the number of contractors on site and speeded up the construction programme.
