Masonry fixings - UdiASSEMBLY


UdiASSEMBLY Masonry fixings are:-

  • easy to use
  • heavy duty
  • thermally decoupled
  • great for fixing all insulation boards to masonry walls.
  • perfect for fixing the UdiRECO system or for boards where precise adjustment is required.
  • ideal for fixing into difficult substrates such as Porotherm blocks

Where are they used?

  • UdiASSEMBLY Masonry fixings are suitable for internal or external use on to all types of masonry including soft brick, stone, Porotherm, concrete block and in to rendered surfaces.

How are they used?

  • Simply hold your insulation board in the desired position.
  • Using an 8mm drill bit, drill through the board and at least 70mm in to the substrate and then clear the hole by moving the dril back and forth 2-3 times.
  • Put the grey masonry plug on the end of the screw and insert in to the hole so that the plug goes in to the masonry and reaches the stops.
  • If the masonry is very soft, a small amount of grease on the tip of the screw helps.
  • Once this is in place drive the screw in to the wall and stop once the head is level with the surface of the board.
  • Finally, insert the green plug in to the head to prevent any plaster reaching the head of the screw.

How many will you need?

    • Each box contains 100 screws. Depending on the system, you will need between 6 and 9 fixings per square metre.
    • Sizes refer to insulation thickness, not screw length.
