I have a DIY job on hand and would appreciate any advice, dry lining a single leaf mass concrete wall.
The house was built in the 1950's and I have the walls stripped ready to dry line.
I do not want to have condensation problems in the house after, so I was considering the following
2x1 lath on to the wall leaving an air gap there for air circulation, 25 mm insulation board on to the lath. 2x2 stud outside this filling with 50 mm insulation. Next is an isovar breathable vapour barrier and then 1/2 " slab and skim.
I would value opinion 's. Would the above would stop interstital condensation developing.
I was wondering would I also need to use a breathable insulation board or would the ordinary kingspan sheets do or possibly the standard attic fibre glass, my concern is that the foil on the kingspan would cause condensation or will the vapour barrier solve the problem on its own.
I would really appreciate any advice.
