Hi, help and advice needed.
Recently moved into a 1960 as built dormer roof / pitched roof house. Bloody freezing !. Found only 25mm insulation under the boarding in the pitched roof loft and only 25mm in the dormer flat roofs. Both open to each other via the 200mm roof / ceiling joists. No sign of an vapour control layer.
My plan is to strip the flat roofs and insulate as a warm roof and insulate / vent the pitched roof as a cold. My concern is around the junction of both and how to cross insulate and the correct line of vapour control.
Hopefully my pictures and drawings make this more clear.
As usual, any guidance and help gratefully received.
Graham.
