If im insulating a single brick structure. Plan to batten out the walls to, for sack of argument, 50mm, put insulation in the gaps, either wool/fiber or king span (if this makes a different to the answer please let me know) and then cover in either plaster board or OSB etc.
Should i use something like 30mm of insulation with an air gap? Ive heard this thrown around that you need one. Should it therefore be against the outside wall or the inside boarding? and do you therefore need vents in the wall/boarding top and bottom?
Thanks
Luke
