Hi, the walls in our house have been fitted with a damp proof membrane on the walls on the ground floor and the first floor (the type you might see used in basements) this is fitted straight to the wall and then battened and plasterboarded over.
I have just started removing the plasterboard and have seen that there are a lot of water droplets holding between the damp proof membrane and the wall is giving off a damp smell.
(This work was all carried out by previous owners)
I am planning on removing it all and using kingspan/celotex type insulation but what is the most effective way of fitting it without causing any further issues afterwards.
I was originally thinking about battening the wall and then fitting 62.5mm insulated plasterboard to it but the price of insulated plasterboard is twice the price of buying insulation and plasterboard seperate.
Should I leave an air gap between solid walls rather than tightly fitting insulation against it to prevent the solid wall sweating internally?
Should I fit vents in the plasterboard wall to allow air to get into created cavity?
Should I construct a 2x2 stud wall and inch or so off the solid wall to leave a cavity and fill the frame with 50mm insulation and plasterboard over?
whats the best method?
