I want to insulate an external wall, using either 75 or 100mm PIR board in a timber stud. I can't/don't want to simply dot'n'dab insulated plasterboard.
As I understand it you'd often leave a small gap for running wires/pipes, presumably on the inside of the PIR?
This is starting to get the stud depth quite thick like >100mm, I don't really want to build a stud from 6x2" and wondered if there are any tricks/tips like offsetting the stud from the external wall?
How should the stud actually be affixed to the wall if you're using say 4x2" or similar? Is it simply a case of using really long screws all the way through the studs? e.g. 150-200mm?
Thanks.
