? The BC chap came fir 1st inspection after bricking up garage door and side door. All is good. He asked me about how I will be contracting my studwall and said a cavity 20-50mm is std practice with at least one inner course of brick.

I also am wondering how the sole plate is fixed to the brick course. The nails or screws through the sole plate into the brick would need to pierce the dpc and dpm. Is there a trick here to aviod this or is a bitumen sealer required around the pierced spc & dpc

any other input pls chaps

I get your method of saving space is handy. But if the my guy said I need a cavity between 20-50mm I guess I need to go down that road. the cavity helps with leveling the piers so not such a bad thing. but now addressing having a non vented cavity? can I do liquid dpm on wall or hang vdpm down...

it's crazy how much variation there is - the image I posted was addressing goncg69's comment that Rockwool can't be used in stud walls. The image was from LABC's own website for garage conversion guidance. I do appreciate the replies. Do you concur with goncg69 about the rockwool or is it a non...

I've planning 100mm Rockwool between and 20-30 PIR over - is that ok

That's why I am planning to use PIR sheeting over the front of stud wall - would this not address that issue

on the warm side? what do you think of the vapour barrier (tyvek) on the cold side?

Local BC guidance details 60mm pir or 90mm rockwool.

or liquid dpm on walls?

my original plan didn't have a cavity but on the inspection after doing my brickwork he said a cavity IS required.

can I add a dpm up the wall and still have a cavity? how would the dpm be fixed to the wall or do you mean fixed to the timbers studwall?

100mm knauf 32 is pretty high spec and an additional 20mm pir sheet over it surely is good enough.

Well I'm working to building regs and if the bc inspector specified that I need a cavity - should I just ignore him and hope he doesn't look on his next visit
