I've done an extensive search here, but still confused about how to proceed...
Single block construction, pitched roof slated garage, rendered on the outside and painted.
Looking to insulate my garage to make it more comfortable as a workshop and to prevent rust on tools etc.
The roller door is an issue, I was going to replace this with uPVC doors, unless anyone has a cheaper suggestion? I'm guessing trying to insulate it is wasted effort?
With the pitched roof, I was just going to put celotex 50mm or 75mm between the rafters and ply over it leave it at that but do I need to leave any air gaps between that and the roof membrane that is already there? Or is anything else required like vapour barrier?
With the walls, I was going to create a wooden batten frame, directly to the walls and fill the gaps with celotex also and then plywood as I want to hang things on the walls. Do I need a vapour barrier between the celotex/battens and the ply or the wall? Or any air gaps within this?
Thanks for the help!
