    I’m sticking a porch on our house. Flat roof, timber on a concrete slab.
    I know I have a breathable vapour barrier on the cold side/outside. But The thing I’m a bit stuck on is should I have a damp roof membrane on the inside.
    Am I right with the wall make up, from inside to out-
    Plastetboard
    Damp proof barrier
    Stud wall with 100mm foiled insulation
    OSB
    Breathable membrane
    Batten
    Feather edge cladding

    thanks
