When using a house wrap as a weather-resistant barrier wrb, it must meet the 2018 international building codes requirements of a wrb for water-resistance and vapor permeability.it must also meet the 2018 international residential code irc for water resistance irc r703.1.1.a superior house wrap is air- and moisture-resistant, permeable, and has a high uv-resistance and tear strength.
When a vapor barrier is on the side of a wall where the dry air is i.e., outside in winter or inside in summer, moisture problems can occur. a vapor barrier reduces the movement of water vapor by diffusion. holes in the vapor barrier that allow humid air through may allow a lot more water vapor into an assembly than the vapor barrier is stopping.
Oct 03, 2015nbsp018332ive wondered several times if installing a vapor barrier on the ground under a deck would help mitigate these problems. were doing one now that seems like a good candidate for this idea. its a new cedar deck around a pool. the boards are installed tight together, so any moisture vapor from underneath couldnt escape through the cracks.

How vapor barriers work . one method of controlling crawl space moisture is with a very simple and inexpensive project laying out rolls of ordinary sheet plastic. traditionally, this plastic has been called a vapor barrier, but this strategy has been retitled by the u.s. department of energy, which now defines it as a vapor diffusion barrier.
Barricades 6-mil plastic sheeting is construction-grade plastic film for use in a variety of heavy-duty construction, gardening and diy applications. this heavy-duty plastic is commonly used under concrete slabs as a vapor barrier, on top of freshly poured slabs as a curing blanket, and as a temporary cover for equipment and supplies.
Polyethylene sheeting is the most common vapor barrier material. a 4-to 6-mil-thick polyethylene sheet is typically placed on a compacted sub-grade or on a sand layer spread over the subgrade. some specifiers prefer thicker polyethylene sheeting, especially if the vapor barriers under concrete slabs
