Hello!
Building partition walls in an insulated and heated standalone building/garage where on one side of the wall it will be a storage/workshop and on the other side a guest room/office.
45*70 studs with 450 cc.
It will be OSB on the inside with single plasterboard outside mainly for sound insulation. My question here is do I need to put plasterboard on the side towards the storage area? In this room, sound insulation is not important. Stability and support for wardrobes/shelves will already be provided by the OSB board. I plan to plasterboard the side facing the guest room/office over the OSB.
The property is quite secluded without disturbing noise from, for example, traffic, so additional soundproofing is not important (since these are interior walls).
Suggestions?
