    hello all, old cottage renovation. For anyone with a corrugated roof,can I ask you please how is your roof make up? What size battens did you use and how far spaced? and how did you insulate your roof? I want to put up corrugated sheets too on my cottage and will be insulating from underneath afterwards. thanks a lot, Buky

    Thicker the rafters the easier it is to put lots soft insulation.
    I used
    6x2 rafters 600mm spacing
    3x2 batons about 1000mm spacing
    Very exposed so over engineered.

    Don’t forget to put breather mem brain over top of rafters under battens.

    Quite offen see corrugated roofs with 4ft rafter spacing from 3x2. Not sure there were Desighner to have insulation plasterboard solar panels etc on them.

    Thanks lightson,

    did you just use the earthwool insulation? And how is the sound when it rains? Did you use plain galvanize?

    Appreciate the input.

    Why are you choosing to insulate under rather than over the rafters?
