Gents,
Currently have 100mm celotex in between ceiling joists of tiled roof, which covers the kitchen. Now I want to insulate across the rafters before I plasterboard the ceiling, I still have 100mm celotex sheets left and was wondering whether using those would be fine, or is it overkill. As I would rather not spend any more money on say 50mm celotex.
Thanks
