Insulation at lock-up in Oran Park NSW

Wall and ceiling insulation is installed in the few days between the services being complete and the linings going up. We have recorded it simply not installed on Oran Park jobs, in more than one area of the same house. It is not a dramatic finding and nothing falls down because of it, but the energy rating your house was approved against assumes it is there, and once the plasterboard is fixed nobody will ever see the cavity again. It is the clearest single argument for booking the lock-up stage.
