Insulating my ceilings downstairs...

    Hi there,
    In the middle of a build at the moment. Am drylining outside walls. Bison slabs on first floor. Metal stud in place. Want to insulate to stop heat rising through ceiling to slab and 6in of outside wall which isn't insulated by drylining boards. Insulation backed plasterboard isn't really an option as I'm putting spotlights all over the shop and each light would need to be cut around to give enough space so bulbs don't overheat etc. Nightmare. So need another solution. Someone mentioned putting rockwool / similar in the metal stud framework. Would it be worth my while doing this? Any ideas on how I can achieve the best results given that I'm insulating the ground floor well at floor level and drylining so don't want the heat finding an easy path out.
    Hope someone can help here.

    and obviously, the advice will vary depending on where you refer to

    Why not insulate above the slabs?

    My read here is that the dry-lining is stopping at the ceiling level, which has a 6" space between it and the ceiling floor-slab. it is this space that he wishes to insulate.

    That's it exactly Carlow, thank you.
    I want to stop the heat downstairs travelling up through the ceilings to this uninsulated area.

    Interesting post.
    This may be an area often overlooked by builders/specifiers.
    I expect the insulation in the cavity might need to be upgraded at this point. But difficult to say without a detail.

    am probably missing the point here but why not run the drylining up to underside of slab before fitting ceiling.
    Then 'dryline' the underside of bison slab and then the 'false' ceiling can take all those 'ugly/energy wasting down-lighters':)
