“Avoiding Air Barrier Pitfalls” by Gale’s Brian H. Neely, AIA, CDT, CBST and Robert F. Mimmo, CBST was published in the November issue of Durability & Design. The article highlights dos and don’ts of installing air barriers through the exploration of four case studies. Below is an excerpt:
Air barriers, when correctly installed, help buildings achieve high levels of energy efficiency by decreasing heat loss. For example, great pains are taken to stop the uncontrolled passage of air through building envelopes of passive houses, which routinely reduces energy consumption 80 – 90 percent compared to traditional buildings (according to the U.S. Department of Energy). But, when air barriers are incorrectly installed, they can cause problems for buildings, including deterioration of sheathing structural members, and can contribute to the formation of mold in the wall system.
