    usually me and the team use 100mm Celotex but always belive it doesnt allow an air gap.90mm Celotex is perfect and allows an air gap.

    Architect advised to use 100mm Celotex, I used 90mm Celotex and was a lot better for my joists.

Question:

My builder wants to cut a full size 2400x1200x90mm Celotex board down into cavity wall boards (1200x450)and use it for the cavity wall instead. Is this ok?

Answer:

Generally speaking, they are the same product, so I know many builders that take this approach. However, it is worth looking at the other products that Celotex make. Either 85mm or 100mm CW4000 boards would be a good choice. If it needs to be 90mm the Celotex do make a product called Celotex Thermaclass Cavity Wall 21 90mm which may suit your project better.
