February 16, 20233 yr I thought the gap between ceiling and structure had to be at least 30cm . Understand this requirement for timber joists etc . But if it’s a concrete ceiling ; what is the min ? ta !
February 16, 20233 yr There isn't one as far as I know, Our Building Control scrutinised drawings show a 50mm gap between the inner face of the plaster board and the inner surface of the rafters / joists and that is all the service void we have. If you have to have 30cm (300mm) everywhere rooms would be so much smaller.
