According to him it's quite common, because most builders just use traditional roof truss sizing, which doesn't allow enough space to fit modern insulation batts properly over the walls - so they either compress the insulation to fit it in (which destroys much of its effectiveness), or just finish the insulation short, leaving a gap (which, as pointed out, makes a mockery of the modelled energy rating). Simply specifying the roof trusses to have a 150mm chord overhang is simple and easy to do, gives enough space for an R6 or R7 batt to cover the wall, and doesn't make the truss any more complex - so there's really no excuse for builders not to do it. Good luck with the VBA! Agreed, and my insulation installers simply took the easiest way out, not taking the time to cut wall batts properly or install the ceiling batts properly. Such huge gaps along the ceiling edges all over the house is just ridiculous. Even more ridiculous is that they have kept saying with certainty that it is common. Our 6m high Cathedral ceiling has 0 insulation, just plaster, wrap and tiles as far as I can tell.
