Hi handyman..at the moment, there is no vapour barrier. There is just blown insulation on top of bare drywall...I wanted to know if I can install a vapour barrier between the joist bay (toward the warm side)...
I cannot seem to find faced insulated batts...where can I get that? isn't the poly plastic better? if so, do I just staple / tape the plastic between the joist bays or run them over the joists as one long piece of vapour barriered plastic? thanks
