My concrete panel garage became a man cave 10 years ago when we built the house extension and the garage had to be halved in size. The garage door was removed and that side bricked up with brick and block.
I keep getting the itch to convert it properly into a "garden room" in that to insulate and sheet the inside , walls and roof (sloped not pitched).
Any experts on how best to do this and what to use? I see all sorts of conflicting advices on moisture barriers, vapour barriers, rockwool v boards. In which sequence to do these, some say vapour barrier against the concrete - others say between the plasterboard and the insulation. Due to the design of the concrete panels I am thinking the rolls of insulation would be better than the boards as the edges of th epanels are tapered in.
Also how do you actually affix the vapour barriers (depending on where they go). For the ceiling There is probably around 100mm of clearance so I thing that leaves plenty of space for insulation as well as leaving the airflow gap.
Any advices would be appreciated and hopefully might help me get my mojo back and desire to get on and do it.
