house wrap in the basement
I have seen this on the TV show DIY Disaster, by the host/expert, and wondered if anyone sees a problem with this.
First off, I should say I am considering the Building Science method of insulating the basement walls, with the closed cell foam insulation against the foundation wall and sealed to provide the impervious envelope, then the stud wall built inside of the foam, then the stud space filled with fiberglass insulation, no vapour barrier, gyprock with alkyd paint.
However that would add additional thickness to the wall, which would make a difference in an already small room size.
The method I saw was to apply housewrap (Tyvek) against the wall surface (actually, they applied it to the prefab'd (on the floor) stud frame sections and lifted the sections agaist the wall. Then fiberglass in the stud space, PVC vapour barrier, then gyprock.
I guess the intent was the house wrap would provide a contact barrier between the wood studs and the concrete wall and floor, and also air infiltration barrier, but it would not act as a vb on the cold side of the insulation.
