The use of the proper air barrier material is an integral part of achieving a resilient and efficient building by protecting it from unwanted air and water penetration. In order for this necessary protection to take place, it is critical that the material be fully tested to ensure that it is able to perform in the environment that it is going to be exposed to. It is key that the selected air barrier material has low air permeance and high resistance. The most common test method to ensure this is ASTM E2178, the Standard Test Method for Air Permeance of Building Materials. Our ASTM E2178 Technical Bulletin shines light on how this crucial assessment takes place and why it is important for all air barriers to go through the rigorous ASTM E2178 test method.
In addition to the ASTM E2178 tech bulletin, we offer several other technical bulletins that describe the multiple testing procedures that are commonly used on W. R. Meadows products. These informative documents are helpful items when it comes to installing, selling and/or specifying products. There is even a handy page on our website that categorizes all of W. R. Meadows’ products by standards and approvals, including ASTM E2178. If you have any comments on our technical bulletins or any suggestions for one that you’d like to see created, feel free to comment below.
