ABAA has developed standard industry specifications for the evaluation of a material as an air barrier material. The standard material specification also includes requirements for determining the water vapor transmission properties of the material. Where the material can also perform as a water resistive barrier and as a heat barrier, requirements for testing are included. Materials that can provide more than the air barrier function are specifically identified.
