Ignoring for a minute whether a vapor barrier is a good idea, the general rule of thumb is to place any vapor barriers on the warm side of the enclosure. So, without saying that you need one, if a vapor barrier is specified, it should be on the inside of the wall in heating climate...
A combination air barrier/vapor diffusion retarder may be a better choice for this situation. Knowledgeable builders typically use vapor diffusion retarders with ratings of 0.1 or less. However, if you carefully seal the warm-side vapor diffusion retarder and interior finish, you can also safely ...
the moisture condenses out of it. This means that a vapor barrier needs to be placed on the warm side of the insulation to stop warm, moist air from condensing on a cold surface inside the wall. In cold climates, where the outside...
Laying up I find that I can keep most of myself warm enough, but my feet are the cold spot. Having used my Terroc 330s with a UPS plastic shipping bags as my poor man's Vapor Barrier Socks on a snow mobiling trip one afternoon at Lake Tahoe, I was pleasantly surprised to find ...
Answer: one option is to insulate the floor above the crawl area with a vapor barrier on the warm side of the insulation (over the joists) and to leave the crawl space vented in all but the coldest weather, perhaps using thermally operated foundation vents (1980's convention). Low ...
Above- and below-grade walls both require a high-quality air barrier(R402.4.1.1). In addition, the climate zone determines the need for a vapor barrier on the interior side of framed walls (R702.7) Image Source Defining Air Barriers
Q.Should the vapor barrier go on the inside or the outside of a building? A.In [climate zone4C, 5 and above] code requires you to put a vapor barrier on the inside. That’s because the strongest vapor flows are during cold weather from indoors out. ...
to the cold outdoors in the winter. The reverse is true in the summer when the hot sun radiates heat down on the roof of a building. Radiant Barrier insulation installed in the attic will reflect the majority of heat back to its source, making your internal ai...
In cold climates, for example, the membrane is placed on the warm side of the insulation (i.e. between the insulation and interior finish) which prevents moisture condensation from penetrating the insulation. However, in regions where variations in climatic temperatures are significant, placement of...
