    i'm completely retrofitting new flooring and rigid insulation to the upstairs dormers in our recently purchased 80's house. bit of info about the pic, it shows 50mm of rigid between the timbers at the min, and i will be overboarding with 100mm then plasterboard over the top. in the timber areas.


    the lovely pink scabby wall is the internal side of the gable end, it has some kind of white extremely light/powdery substance in the cavity as insulation.

    this room is going to be my sons room and we want to clad the whole of that wall with reclaimed timber, it will also mean we do no need to get it skimmed etc, something along the line of the pic below


    i'm thinking about battening out from the wall 30-50mm, then between the battens adhere 30-50mm celotex or similar foil backed insulation. then cover the battens with foil tape (to have one complete unbroken foil vapour barrier)
    Then use the battens to secure the cladding.

    can anyone see any issue with this? do i need to add another vapour barrier somehow? and what would be the most effective method if so?

    any other advice welcome:)
