Hi all
I am about to insulate my fish house that is a single skinned breeze block building , would it be best to screw / nail /glue the kingspan 40mm sheets directly to the wall and then
spot and dabbing plasterboard over the kingspan sheets or do you have to put up battens and insulate between them. The reason i ask is i am unsure whether i have to allow for any ventilation gap between the insulation and the plasterboard as i know you have to for the ceiling.
