    Just about to restore a bungalow. I realise that insulation and the house being fairly air tight is important. Lmecrete flooring has been advised as the best option. Plus an optima dry lining metal stud system sounds really efficient. Any ideas appreciated. TIA

    The Optima drylining system is probably your best bet if external wall insulation is not feasible. The system will be wider than an equivalent insulated slab lining system however it is the best way to ensure that there is a functional vapour control layer which will reduce the risk of interstitial condensation and mould growth

    In relation to the floors, are you intending on taking them all up? If so, your best option is probably to lay radon barrier, PIR insulation and a concrete slab. I’m not sure why you would just lay limecrete if you are replacing floors?

    Without someone doing a detailed survey of the house and giving you the varying options based on your budget you will not know what is best for you.

    Isover may be all fine and dandy on windowless, doorless walls, and if you look the brochure sfs about dealing with existing window and door reveals, which is where a lot of the action is for thermal bridging
