The air barrier technology used in today’s construction and mandated by the International Energy Conservation Code (IECC) are firmly grounded in science. That database of knowledge continues to grow at an astounding rate. Research efforts by the Air Barrier Association of America (ABAA) will be presented at the ABAA Conference in 2019, and you will be astounded by how much research and testing that ABAA has been conducting to ensure better knowledge for all.
Currently, air barrier systems are being marketed with having passed only the air barrier part of the testing (ASTM E2357 - Standard Test Method for Determining Air Leakage of Air Barrier Assemblies) and pay little to no attention to the other architectural performance attributes, such as crack bridging, water resistance, adhesion to a substrate and fastener sealability, which when successfully passed, results in an ABAA Evaluated Assembly.
So, what I’m asking you to consider is an upgrade of performance requirements for a better and stronger air barrier specification. Here are my suggestions for ensuring the best possible air barrier performance for your project:
Performance requirements for a proper air barrier specification are vital. The above are four of my suggestions as how you can elevate and upgrade your specs. Should you have any questions or comments, I appreciate you commenting below. Thank you for reading.
Let's Fix Construction is an avenue to offer creative solutions, separate myths from facts and erase misconceptions about the architecture, engineering and construction (AEC) industry.
