Celotex?

[paulsa]

Hi

I have already battened a poor condition external wall and have moisture resistant plasterboard to go on the battens.

The question is would it be a good idea to put celotex between the battens, then a moisture block (black DP course) ontop of the battens and then the MR PB?

Regards

Paul

If you doubt the weatherproofing of your existing wall then some Blackjack or similar would not be a bad idea, you would normally put on before the battens though but I expect you know that already.
