I am currently in the process of renovating a back room that would get very cold in the winter (we live in Ontario, Canada). After gutting the room I noticed that there was no house wrap under the siding. My question is, can I apply house wrap from the inside, between the studs before I insulate and apply a vapor barrier? Does the house wrap have to sit on the exterior of the house between the siding and the wall or can I go ahead and tack it up inside?
Thanks
Rene
