[Cob] Superinsulation in Victoria, BC

[Anna Young]

I am looking for guidance on the appropriate amount of insulation to use in 
our top floor walls and roof. We have pumice cob and strawbale infill on the 
first floor, but are confustigated about amounts and options upstairs. 
Husband (tall and really likes his headroom and quick construction) and I 
(short and really wanting low energy costs for next 100 years) are having a 
hard time finding insulation levels we can agree on. To save one of us 
stuffing the other into the wall cavity for some peace, I am looking for 
input and links to suitable insulation levels in our climate. It rarely gets 
over 30 in the summer for long and rarely freezes for more than a week in 
the winter. We would like to superinsulate with something fairly green and 
low energy.
