Annotation

This specification covers the minimum performance and acceptance criteria for an air barrier (AB) material or system for framed walls of low-rise buildings with the service life of the building wall in mind. The provisions contained in this specification are intended to allow the user to design the wall performance criteria and increase AB specifications to accommodate a particular climate location, function, or design of the intended building. This specification focuses mainly on ABs for opaque walls. Other areas of the exterior envelope, such as roofs, floors, and interfaces between these areas are not included in this specification. Also not addressed here are air leakages into the wall cavity, that is, windwashing. Additionally, the specifications in this standard are not intended to be utilized for energy load calculations and are not based on an expected level of energy consumption.
