on our master bath (its like 40 sq feet) we have 2 walls that are outside walls.. when I tore the old plaster off there was no vapor barrier.. around the shower had yellow insulation with a foil backing, everywhere else was blown in insulation..
now that we are down to the studs, i plan on using the typical pink stuff with the kraft paper that is tar backed.
I have read that the kraft paper w the tar back is a vapor barrier enough an not to add a plastic on top as this creates a double barrier causing air stoppage.
i have also read that if you live in an area where your A/C us used most to put the barrier on the outside (closest to the room center)...and where you use the heat the most to put the barrier on the inside wall. ..
well here in cleveland ohio we use the HVAC pretty equally (but we complain about the cold more :laughing
.....so what should i do?
THanks for the tips!
oh i forgot of course we will have a nice big exhaust fan in the room vented properly with a fatty 4 inch out the roof.
