    Hi,

    We have a hallmark stone wall on three sides of the house, with a 50mm cavity, inner leaf and 50mm insulated board on the inside of the inner leaf.

    Have seen where cavity wall insulation is not advised with hallmark stone as per Roadstone's advice Has anyone filled the cavity of a similar type property?

    Was the insulated board installed when the house was built or retrofitted sunsequently?

    The reason I'm asking is that filling the cavity with for example bonded bead may have absolutely no impact on the heat loss regardless of what the outer leaf is composed of.

    Hi Mick,

    The board was installed when the house was built- its on the inner leaf and has plasterboard on top.

    Thanks!

    That's as I thought. Chances are then that insulating the cavity will have negligible impact on heat loss as your primary heat loss mechanism is likely convective rather than conductive i.e. draughts and air leakage.
