How do you see the use of hot air/flame applied bituminous sheets as a vapor barrier on roofs regarding VOC? Which category should I use? Or should I even count it to meet the compliance with this credit?
It is not a part of primary waterproofing system, but maybe it can be considered a secondary waterproofing system. Does the addenda to the ref. guide exclude this as well as singly-ply roof membranes?
