More E 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.

It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.

Scope 1. The intended users are purchasers of the AB, specifiers of the AB and regulatory groups. Air barrier performance and specification minimums were selected with the service life of the building wall in mind.

The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard. This standard does not purport to address all of the safety concerns, if any, associated with its use.
