Parapet wall air sealing detail
I’m in climate zone 3 in southern California. I have flat roof to retrofit. Right now the roof is open on top and bottom. The outside wall is stucco with historical detailing so I need to leave that in place.
The walls were balloon framed. Does anyone have advice or a detail on the best way to air seal in this setting?
Would you suggest rigid insulation the outside or cc spray foam on the inside.
The architect is calling for can lights. I have read enough on this site to know that they can cause some serious problems. If enough insulation is above the roof sheathing does that make them more feasible?
