Now most of the insulation is done I will soon be getting to fitting the inside walls and boarding the ceiling over the top of the insulation. Still got to insulate the roof, hopefully I have enough insulation board left.
Although expensive I'm thinking about ply walls and ceiling.
22mm plywood for the walls screwed into the stud walls and 18mm ply for the ceiling.... Is this a good way to go ? Someone said plaster board was an option but I think ply should be easier to fit and work well.
Is all ply generally the same? Is marine ply overkill ?
