How Curtain Wall Consultants use Transition Membranes for the Continuity of the Air /Water and Vapor Barrier Systems for Exterior Walls(PPT)Energy code requires continuity of the air / vapor and water barrier system at penetrations in the building envelope. Durable and flexible materials are ...
Build smarter to avoid wasting energy through a leaky building envelope. 3M exterior air and vapor barrier products are designed to reduce air leakage and prevent condensation that can negatively impact building materials, air quality and the health of o
If the vapor barrier is on the outside, it prevents the humid air from diffusing into the wall cavity and finding the cold surface on the other side of the cavity, the back side of the drywall. So, like a vapor barrier on the inner surface in cold weather, putting one on the...
Vapor barrier The phrase vapor barrier is often used to refer to any material, typically a plastic or foil sheet, that resists passage of moisture through

Exterior foundation insulation will help keep the foundation wall warmer and less likely to condense water in winter and summer. By the way, if you've got standing water or even occasional wet floors in the basement, vapor barrier placement is a moot point - you need to solve the water pro...
Vapor barrier Acronyms Wikipedia vapor barrier [′vā·pər ‚bar·ē·ər] (civil engineering) A layer of material applied to the inner (warm) surface of a concrete wall or floor to prevent absorption and condensation of moisture. ...

However, other building science research indicates that it should be applied directly under the exterior finish and is sometimes itself the exterior finish. A combination air barrier/vapor diffusion retarder may be a better choice for this situation. Knowledgeable builders typically use vapor diffusion ...
