Foiled back Wall Insulation

    Has anybody used this type of insulation for block walls. It is used extensively in the States, although there it is for timber frame construction, and placed on the outside. In Ireland, I assume it would be used as a form of dry-lining with 215mm blocks

    It is claimed that it gives very low u-values but would not require the same thickness as traditional insulations.

    Anybody any experience or views?

    most wall board insulation is "foil backed"... i think youre misunderstanding something....

    if your referring to 'multi foils' theres plenty of threads on this already, do a search.. .definitely an eye opener......

    I meant to say aluminium reflective insulation.
    Am I allowed to say the company name on this forum?

    you dont have to...

    search for 'multi foils.'

    have a look here:

    theres a hell of a lot in it...


    but basically in a nut shell....
    it has been proven to have a similar thermal conductivity as as about 38mm of mineral wool. It is NOT a substitute for more traditional insulations... its basically a vapour barrier that has insulative properties...
