Not immediately useful for the OP, but in one of the Grand Designs programs they looked at a timber-framed house that was being built according to Scandinavian techniques, where of course the winter minimum is very low.....
....instead of using 100mm stud frames as we do, they were using the I-beams with a ply web, such as are used in project brick-veneer homes for upper floor joists, but using them vertically as studs, rather than horizontally.
They then attach battens both inside and out, and attach cladding to these battens. I don't recall whether or not they used reflective foil barriers, but I vaguely recollect they may have done.
In any case, the insulation used was flame-retardant-treated waste paper, blown in from the top of the wall once the cladding was in place. Actually, they dropped the feed pipe in till it reached the bottom plate (no noggins, of course) and then slowly retracted it as the insulation was blown in.
Apparently, houses so constructed are quite comfortable at -20 deg C.
The depth of the I-beams was 250mm (I think), but for our climate, probably 150mm would be quite adequate.
Anybody seen anything like this anywhere in Oz?
