Hi Guys,
I have built an extension on top of a single storey ground floor extension. The original extension only had a 50mm cavity so the new build has the same. My building inspector has told me that because the cavity is only 50mm then i must fit plasterboard with a 50mm insulation. My question :-
Is there anything else i can use that is thinner that will satisfy the inspector?
Thanks
