The Air Barrier Association of America (ABAA) develops master specifications for various air barrier assemblies that will provide guidance to the design professional in the development of the final project specifications. These assembly specifications combined with proper installation details will provide the guidance for building professionals to specify the air barrier assemblies and to develop an air barrier system for their building.

ABAA has developed a Position Paper to encourage placing all the requirements for air barriers in a separate section where a single contractor can be responsible for the air barrier assembly.

ABAA has also developed Division 1 Specifications which provides administrative and procedural requirements for specifying an airtight building enclosure that controls infiltration or exfiltration of air, inspection and testing services required to verify compliance with requirements specified or indicated, necessary information for the coordination between subcontractors required to provide an airtight building enclosure, customized fabrication and installation procedures, not production of standard products.

ABAA Air Barrier Master Specifications

These specifications provide guidance to the design professional. Depending on the material used, these specifications are for an air barrier assemblies consisting of various materials which may or may not be vapor permeable.

Where these materials provide more function than the primary air barrier material, the design professional shall consider other design requirements for the material to fully deliver the intended function and to design the wall based on proven documented building design principles.

The design professional shall consider where these materials shall be placed in the wall assembly based on the function(s) they are intended to provide, test property results (ie. vapor permeability) and the climatic conditions where the project will be located.
