Insulating Cavity Walls

    Hi,

    I am building an extension. The now fired builder built up the 3 cavity walls but put no insulation in them. The walls are fully built but there are no windows in or roof on. Can I rescue it at this point, is it possible to put the insulation slabs in the cavity walls? I'm guessing I'll have to cut it in strips to work around the wall ties. Will this be OK and prevent the need for insulated plasterboard inside? I can get the cavity pumped also at the end to fill gaps.

    Thanks for any advice
