Timber frame house renovation

    I own an older (built in 1972) timbre frame house. The frame in in great condition but the plasterboard is crap (paper is peeling) and it has little or no insulation in the external walls.

    I plan (on a room by room basis) to strip down the plaster board insulate and reslab (will rewire and look at the plumbing at the same time)

    My initial plan is to use 4" of rockwool between the battens and then a 37mm insulated slab on top (to act as a thermal break and to add to the total insulation) finished with a hardwall skim-coat.

    My questions are

    Will this provide sufficient insulation ?

    I have been told that the insulated board will act as a vapour barrier. Is this true or will I require an additional vapour barrier ? (all electrical outlets will be plasterboard boxes with a caulking gasket any other "breaks" due to pipes etc will also get a caulking seal and will floor and ceiling joints)

    Someone recommended that I sheet all walls with a plastic (taping all joints) pump with celulose and then insulated slap on top.

    Would this be a better alternative ? My fear is that this would make the room effectively airtight and require some form of forced air movement.

    Alternative ideas welcome.
