I'm working on insulating a space now and was hoping someone could give a final answer on how to properly insulate without creating condensation inside the wall.
Here's what I'm thinking... from the outside in: osb, tyvek house wrap, 2x6 stud walls stuffed with r19 fiberglass, 6mil plastic vapor barrier, 2" firring strip for a dead air space, 2" rigid foam board, 6 mil vapor barrier #2, final layer before grow space is reflectix or foil covered 1" foam board with taped seams. I'm going for overkill, but is this over the top?
I'm just throwing out ideas above, if you can suggest something better please share. Thanks!
