    I've just moved into a house which has a timber stud/felt/clad wall to the front and to my surprise there is no insulation inbetween the studding.
    I'm thinking 50mm kingspan/Celotex between the studding, maybe even another layer over the studding and maybe board it off.
    Will this create any issues with condensation or breathability?
    Thanks in advance.

    If this were roof timbers you would - Leave an air gap between insulation and outer covering, add another insulation layer over studs on inside, apply vapour barrier (very very important) then finish with plaster board or whatever. This is Similar construction to roof only vertical so i imagine same thing applies
    Could ask Celotex/Kingspan, they are very helpful and have good info on website
