I am insulating the upstairs of the garage I am building as I am using it for an office space.
The shed is a block and a half, so upstairs has about 2 blocks and then the ceilings on the widths and then the unplastered block gables.
I am planning on using 38mm insulated plasterboard on all walls and ceilings.
So I think I will be using the fixings for attaching the blocks, not unless there is a better option, but of the ceilings I am at a bit of a loss as how to attach them.
I will have 2 fluoresant lights hanging out of the ceiling so what do I use to hold these in place?
Same for sockets and light switches, since the plasterboard and insulation is 38mm thick do I just cut out a track out of the plasterboard and run the cables down and attach the sockets/switches?
Sorry for all the questions
Also, to make it air tights as possible, what would you suggest I do before I put up the plasterboard, do I use a membrane of some sort?
