The National Air Barrier Association (NABA) 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 combin ed 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.
NABA 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 cons isting of various materials which may or may not be vapour 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. vapour permeability) and the climatic conditions where the project will be located.
