Vapor retarder definition

Vapor retarder means 6 mil visquene or equal.
Vapor retarder means a ground cover material of 6 mil black polyethylene sheeting or equivalent.
Vapor retarder means a material installed to retard water vapor diffusion into building component assemblies. The retarder shall have a maximum permeance rating of 1.0 as defined in the 1989 ASHRAE Handbook of Fundamentals. A vapor retarder may perform more than one function, such as, but not limited to, an air barrier, referred to as an "air/vapor barrier." Building papers, sometimes called "house wraps," n designed to be applied to the outside of building serve only as air barriers and are not vapor retarders.
