Take a closer look at this product with these additional images.

“A really ingenious way to create load bearing timber structures which hold insulation but don’t need a foundation at the bottom” – Chris Brookman

 

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.
Technical Details

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 a close up of the Facade Expanders on a brick surface with wood fibre insulation between and the 52mm UdiTOP wood fibre sarking boards fitted to the front. The construction will be counter-battened and covered with tiles to fit in with the surroundings.

The Facade Expanders also allowed the installers to flatten out the surface of the wall and make it vertical as in spite of appearing flat at a glance, there was a significant lean forwards on the wall.
