        Hi all

        Would I be right in thinking that rockfloor would be the preferred
        choice for under slab insulation.
        thanks for any advice

        cheers Jim

          If this is Rockwool's rigid slab, then yes it would be OK. You might like to check the minimum density of RW slab suitable for your loading then use that. The cost goes up almost in direct proportion to density, other factors being equal.

          See also discussion “Beware the blanket approach” on this forum but whether you can extract the key lessons from the rest of that discussion I don't know!

          David.

            I'll speak to rockwool about the load etc.
            and take a look at that discusion.

            Thanks David
