Planning on having a complete, properly-sealed, and void-free building envelope? Even if everything it perfectly planned and executed, your barrier will still end up with giant holes we more commonly refer to as doors and windows. This is where flashing becomes necessary to properly seal around these unavoidable barrier disruptions to prevent wood rot, mold, structural damage, or insect infestation. Flashing is a thin layer of waterproofing that eliminates upward facing seams, crevices, gaps, or spaces where moisture could collect and seep past the barrier. Proper flashing ensures a seamless, shingled waterproofing surface that will not interfere with the force…

ASTM E 2178 Standards Explained
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…
