Rainscreen Cladding

Use with proprietary rainscreen facade cladding systems
  • Since rainscreen façade systems are proprietary and use differing mechanisms to fix and support the external cladding to the wall structure, installation guidance should be sought from the system manufacturer or supplier.
  • Insulation boards should be installed break-bonded with board edges lightly butted and in such a manner to achieve a close fit between the board and substrate interface so as to avoid gaps behind or between the boards.
  • Boards should be cut neatly around fixings and brackets, so as to avoid gaps. Where small gaps are unavoidable, fill gaps with fire rated expanding sealant.
  • The number and type of mechanical fixings required to fix Kingspan Kooltherm 15 Rainscreen board will vary with the geographical location of the building, the local topography, the height and width of the wall concerned, the wall structure, and the type of mechanism being used to attach the cladding system.
  • A minimum if 3.13 fixings per m² are required to secure the insulation board to the wall structure.
  • The fixings should be evenly distributed over the whole area of the board.
  • Fixings at board edges must be located > 50mm and < 150mm from edges and corners of the board and not overlap board joints.
  • The joints should always be taped using a 75mm minimum wide suitable self-adhesive aluminium foil tape.
  • Exposed edges should be protected by a suitable self-adhesive aluminium foil tape, with a 50mm minimum wide overlap onto the insulation board face.
