Building science has progressed since then. We know that vapor barriers can cause problems, but we still have homes like the one in Charleston with poly in the walls. And we have $4 million dollar homes with poly on the walls, too. I saw the one below when Martin Holladay came to...
1 Materials used as vapor barriers: 2 Usage 2.1 Basements 2.2 Under concrete slabs 3 See also 4 ReferencesMaterials used as vapor barriers: Aluminum foil (perm = 0.05). Paper-backed aluminum. Polyethylene plastic sheet, 6 mil (600 gauge/0.15mm) or greater in thickness (perm = 0.06)....
While this seems counterintuitive, it is possible for a vapor barrier to actually cause mold. Since these barriers are impermeable to water vapor, they can trap moisture inside your walls if not installed correctly. If there are gaps or holes in the vapor barrier, water vapor will seep throu...

Fluid Applied Air Barriers: Sustainability and Energy Efficiency Energy Efficiency The energy efficiency of the buildings is also enhanced due to the total sealing provided by the fluid applied air barriers. The walls leak less air and prevent moisture thereby increasing the overall insulation. The bu...
A crawl space vapor barrier is a durable, heavy-duty plastic layer that covers the entire floor, walls, and any equipment in your crawl space. Vapor barriers are made to remove groundwater and control moisture in your crawlspace. When moisture and water enter a crawl space, you risk mold ...
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
There are spacing means for varying the distance the open face of the box extends beyond the slanted flange so as to accommodate walls or ceilings of different thicknesses. These spacing means include a curved portion of the cover connecting the flange to the main portion of the cover 90 ...
