I'm having a garden studio built. 4x2 Construction builders paper and shiplap on the outside, plaster board and plastered skim on the inside.
Insulation is 50mm Celotex. The plasterboard is Knauf Vapour Panel board.
Do I need to use aluminium tape all along the joins? That would be a big job - 16 rolls of tape?
I'm being told by the plasterer that it's not necessary - just put it on where there are gaps.
I do tend to over engineer stuff - if I were doing it I would tape it all!
Thoughts?
