Where should vapour barrier be in double basement wall?
Walkout basement in zone 4C (west coast) 2x6 framed exterior wall with r20 fiberglass batt insulation. To eliminate the 'step' (many houses have a finished shelf) of concrete foundation which comes up 2', client wants walls framed from floor to underside joist inside foundation to avoid the shelf, creating a space between the framed exterior wall and the new interior wall. Should the vapour barrier (6 mil plastic be relocated to inside of newly framed wall, and if so, should new wall be insulated? the full cavity be insulated? thanks, dan
