Internal insulation advice

    Im considering installing insulated plasterboard myself. Im considering attaching boards directly to walls with instastik. My reason for this is a bead of this adhesive around the edge of each board should in my mind prevent moisture getting between the insulation and wall.
    I dont understand why battons are used which allow circulation of moist air behind insulation. Im hoping someone with more experience can advise.

    Who is certifying this product will act as a vapour barrier?

    No one.
    I just cant see how I could prevent air from getting from a warm room to a cold wall if I used battons. At least with foam adeshive there would be a physical barrier. This is just an opinion, i may be way off.

    unless you live in a vacuum, you cannot stop air getting ANYWHERE.

    basic science.

    the best way is to comply with the requirements of the products IAB cert AND the principles of good drylining as published by SEAI.

    No insulated plaster board is certified using polyurethane adhesive.

    Do not try to reinvent the wheel.

    Can anyone advise why battons and an airgap are used. It makes sense if the wall had damp issues. But it seems counter intuitive to create an airgap and then attempt to prevent air getting into it.
