Air Barrier Materials, Accessories & Components, Assemblies and Systems
Air Barrier Materials
The testing of an air barrier assembly for air leakage is completed in accordance with ASTM E2178 Standard Test Method for Air Permeance of Building Materials. Air barrier materials (ie. self-adhered sheet air barriers, liquid applied membranes, medium density sprayed polyurethane foam, mechanically fastened commercial building wraps and boardstock air barriers) are defined by their air permeance and the amount of air that passes through them. ABAA and E2178 defines an air barrier material as one that has been tested and has an air permeance less than 0.02 L/(s•m2) @ 75 Pa (0.004 cfm/ft2 @ 1.56 lb/ft2). Keep in mind that air permeance is the amount of air that migrates through a material, whereas air leakage is the air that passes through holes or gaps.
To determine the air permeance of a material, a one meter by one meter piece of exposed air barrier specimen is tested in one of the two following apparatuses:
Test Apparatus for Flexible Air Barrier Materials
Test Apparatus for Rigid Air Barrier Materials
Air Barrier Material Test Requirements for ABAA Listing
For a material to be listed on the ABAA website, the manufacturer shall complete the evaluation criteria process outlined in the ABAA 115-59 Rev 3 ABAA Process for Approval of Air Barrier Materials, Components & Assemblies document. Once a manufacturer has demonstrated to ABAA that their material meets the established criteria and has completed the process of submitting test reports and supporting documents for their material, they will be listed in the tables below as a "ABAA Evaluated Air Barrier Material" and included in the ABAA Master Specifications.
Air barrier materials have product-specific test properties that they have to test to ensuring they will meet rigors encountered in the field. The link above to the process for approval will outline those test properties. Please also see the requirements below for each type of air barrier material:
- Self-adhered Sheet Air Barriers are tested for air permeance, water vapor permeance, resistance to puncture, tensile strength, water resistance, peel or stripping strength of adhesive bonds, lap adhesion, low temperature flexibility, nail sealability, pull adhesion, tear Initiation and tear propagation and crack bridging.
- Liquid Applied Membranes are tested for air permeance, water vapor permeance, nail sealability, pull adhesion and crack bridging.
- Medium Density Sprayed Polyurethane Foam (SPF) are tested for air permeance, water vapor permeance, flame spread characteristics, thermal transmission, compressive strength, density, tensile strength, dimensional stability, water absorption, open cell content, pull adhesion and crack bridging.
- Mechanically Fastened Commercial Building Wraps are tested for air permeance, water vapor permeance, dry tensile strength or dry breaking force, pliability and water resistance.
- Boardstock Air Barriers – Rigid Foam Core are tested for air permeance, water vapor permeance, compressive strength, thermal resistance, flexural strength, water absorption, dimensional stability and tensile strength.
