I have a small kitchen extension with a pitched roof (6M x 3M). My Building inspector has told me to install 100mm board insulation, in the rafters and 25mm insulation boards across these boards.
He also told me that I didn't need to insulate the joists. Having spoken to a few people, they said that this seems strange. Is this correct? I will have silver backed plasterboards on the ceiling and the insulation is silver backed both sides.
Cheers
