Recommended Fixings

  • Framed Structures onto sheathing board: The typical fixing arrangement into Benx Y-wall or Multipurpose sheathing board is 3 no fixings per/m2 using our WX58T screw fixing within a 60 KC insulation washer, plus a KLW 90 insulation retaining plate. In addition, 1 no appropriate metal fixing and should be fixed through the centre of each slab. Benx recommend our WX58T screw in conjunction with our POK 070 washer for this application. Other fixing may also be used which have been appropriately assessed for this application. Please contact Benx Technical department for further information on fixing to our Densglass or other Gypsum based sheathing boards.
  • Masonry Structure: For fixing Cladwool RS back to masonry structures, a typical fixing pattern is 3 fixing m2. For insulation thickness up to and including 180mm, Benx recommend using our KI 10 in conjunction with our KWL 90 insulation retaining plate.
    For insulations above 180mm, we recommend our TFIX 8S screw fixing with a KWL 90 plate. The 1 no additional fire fixing we recommend the use Benx MBA-SS-08 hammer fixing with a MKC-SS-85 washer.
    PLEASE NOTE: Fixing patterns can change depending on specific height and anticipated wind loading requirements, so it is recommended that this is assessed as part of the project review prior to any installation. Benx Technical services can assist in this process.
