Hello,
We've got a 1930s house, and we've recently realised that there is just a single course of bricks between the hallway and the garage. We think that this is why we've never been able to get the hallway warm in the winter. We don't use the garage to keep a car in are so are happy to loose a bit of space in the garage to insulation.
I was going to put in 100mm slabs of insulation from Wickes, between 4x2 vertical studs 600mm apart and then just have a layer of plywood to finish, but I'm not sure which "side" of the insulation the vapour barrier needs to go.
Is it
Hallway - Bricks - Insulation - Vapour Barrier - Plywood
or
Hallway - Bricks - Vapour Barrier - Insulation - Plywood
Alternatively, I have seen that you can get Kingspan/Celotex urethane slabs. Would I be able to fix these straight to the wall and not need a vapour barrier at all? And if so, what do I use to fix them?
Is one method "better" than the other? Kingspan seems like it should be less faff and quicker but might end up being more expensive.
Cheers
Dez
