On the page of your site about dense packed cellulose walls you show an exterior wall with 10" plate & sill and two rows of 2x4 studs. This looks fantastic, but the idea of vapour-permeable membranes on both sides makes me nervous in combination with cellulose. In Ottawa, temp can drop to -25 in winter and reach +30 or more with high humidity in summer. Lots of heat, lots of air conditioning. Are you absolutely sure that no vapour barrier is okay? How do I convince the building inspectors?
Should I densepack wall cavities prior to exterior insulation?
