Sorry for coming in late one this..I hope the gaps have been rectified , but anticon (sisalation & Insulation) is pretty much mandatory on homes these days in WA..did you have an energy rating done on your new house, if so what is the rating?
The reason I am asking is that lately I've seen some energy reports that are completely fictitious and I can assure you the council Building Surveyors and Building Commission would be very interested in such cases.
If your designer or builder hasn't provided you with a energy report contact your Council ASAP, get a copy and have it properly checked.
BTW NON-COMPLIANCE later on may effect you warranty, insurances, property re-sale ,etc,etc
Thanks for the info StructuralBIMGuy! I will have to check on the energy rating report with the builder.
