“A good, sturdy fixing for holding all types of insulation but the teeth in the neck of the plastic head make it particularly good for holding wood fibre insulation boards” – Chris Brookman

 

Product overview.

Where are they used?

  • UdiASSEMBLY 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 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. 

How are they 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 green plug in to the head to prevent any plaster reaching the head of the screw.

Product overview.

Where are they used?

  • As a walling or ceiling board.
  • Between bedrooms and bathrooms
  • Bathroom and kitchen ceilings
  • Stud partitions

How are they used?

  • EBB Clay boards should be fixed using either drywall screws or stainless screws (depending on plaster to be applied) to a timber frame at a maximum of 625mm centres for walling and 417mm centres for ceiling applications.
  • 36mm plastic or stainless steel washers should also be used for ceiling applications.
  • As with all boarding, vertical joints should be staggered by at least 1 stud to avoid cracking.
  • Once the EBB Clay boards are installed they can be plastered with either lime based plasters (use stainless steel fixings) or clay based plasters (normal drywall screws are fine for this).
  • The joints should be reinforced with 100mm wide reinforcing, bedded in the plaster, although fully meshing the base coat works best.

How much will you need?

  • The EBB Clay boards are 1250 x 625mm and 22mm thick, they cover an area of 0.78 m² per board. Allow at least 5% for wastage.

Are they heavy?

  • The boards themselves weigh around 23kg each so need careful handling and for ceiling applications should be installed with a plasterboard lift.

What is their thermal conductivity?

  • The clay boards are not designed to be a thermal insulator but their thermal conductivity is around 0.47 W/mK, similar to many lime or clay plasters.

Material in action.

Here you can see the UdiASSEMBLY timber fixings being used to fix the Diffutherm boards to a timber frame building. Externally you need 8-9 per full board, depending on what the stud centres are. The Diffutherm boards do not need to be joined on a stud as the T&G profile allows them to be supported by their adjacent boards.
