Hi,
as part of my ongoing extension I've built a stud wall with a door to separate my garage from the utility room.
The wall is made from 100mm x 50mm timber and insulated between the studs & noggins with 100mm kingspan (Not foil faced).
The utility side of the wall will have 25mm foil faced kingspan over the studs to stop cold bridging and then 12.5mm plasterboard & skim.
The BCO said that the garage side could be sheeted with OSB 3 so that's what I plan to use, but do I need to put a layer of plaster board on before the OSB 3 to give fire protection?
Do I need to have a plastic membrane on the garage side before the OSB 3 goes on?
Thanks.
