House restoration - PIR to inside of external walls

[Ben100]

Hi all,

 

I'm renovating an old brick house from the 1860's and have been advised by my architect to install PIR to the inside of my external walls for heat insulation. My question is how best to fix the PIR to the brick walls? The existing walls are worn and uneven, so I'm concerned about fixing the PIR with just battens and screws. Is there some kind of foam adhesive that's good for this job? Or am I making this more complicated than needed...?

 

Cheers.

You can Dot and dab the insulation board directly onto the brick 

Then skim the plasterboard face
