    Hi All,

    I'm in the process of buying a standard late 90's 120sqm semi-detached house built with cavity walls & before I move in would like to do as many odd jobs as possible to make it as efficient as possible.

    I was thinking of internally insulating all external walls with something along the lines of this: https://www.goodwins.ie/products/insulated-plasterboard-50mm-8x4-ft.html?filter_set[]=1413,1419

    However I've seen from previous threads that this can cause issues with Thermal bridging & mould however I'm not fully sure if this is in all, or some cases. I would plan on sealing window & door frames thoroughly. Additionally the one wall I wouldn't be doing would be the kitchen as the kitchen will be getting replaced anyway in about a year or two. Would this seem a recipe for disaster?

    For me it makes a bit of sense to do this & then at some stage over the next few months get the cavity walls filled.

    If this wouldn't be recommended, what (relatively cheap) steps would you take to insulate or improve efficiency of a completely empty house? I.e. dust etc. doesn't matter.

    See if you can pump the walls first. If you have time before moving in, see what the attic is like and how difficult it would be to air-seal from above, then insulated (while keeping ventilation to attic space)
