Product overview

Where is it used?

Fischer Termofix Timber fixings are suitable for internal or external use on to all types of timber frames, timber lintles or on to cross-laminated panels.

How is it used?

  • Simply hold your insulation board in the desired position.
  • Make sure the fixing is at least 50mm from the edges of the board.
  • Screw the fixing into the board and then into the timber beneath and stop once the head is level with the surface of the board.
  • Finally, insert the polystyrene plug in to the head to prevent any plaster reaching the head of the screw.

How much will you need?

  • Each box contains 100 screws. Depending on the system, you will need between 6 and 9 fixings per square metre.
  • Fixings should penetrate the timber substrate by at least 40mm so allow 40mm in addition the the thickness of the insulation.
