How do I fix the EBB Clay boards to our ceiling?

Find out more about how we approach this building scenario.

If you are fixing to timber joists then you should use screws with plastic washers and the joists should be no more than 420mm apart. Use 3 screws per joist and the screws should be stainless steel if you are lime plastering over the boards or you can use ordinary dry wall screws for clay finishes.
