24 MARCH 2017 COATINGSPROMAG.COM Specifying Success Air barriers, including liquid applied, are a critical component to meeting those requirements, and it is crucial, therefore, for the members of that team to understand what air barriers are and what they can do. B uilding enclosures require proactive actions by each member of the design and construction teams to deliver a building that meets stated performance requirements. Air barriers, including liquid applied, are a critical component to meeting those require- ments, and it is crucial, therefore, for the members of that team to understand what air barriers are and what they can do. Having this understanding should help minimize building enclosure risks and provide assurance that their projects are proactive in meeting the performance requirements. Here are 10 of the most frequently asked questions regarding air barriers. 1. How do the design, bidding, preconstruction, and construction processes impact air barrier performance? Design is critical to the specification of the air barrier material to match up with the project location, occupancy, sched- ule for installation, and integration of the project specifications to assure that the continuity of the air barrier is maintained from design through construction. e project specification would include the performance field testing requirements per the Air Barrier Association of America (ABAA) Quality Assurance Program (QAP). Bidding is critical to the selection of a construction manager (CM), general contractor (GC), and air barrier installer; the team should have the collective experience and knowledge to plan and implement a successful air barrier instal- lation on the specific project pursuant to the specified ABAA QAP. Preconstruction is critical to the success of the installed air barrier. e preconstruction information should provide the submittals, shop drawings, mockup, first work, and a schedule. e schedule should coordinate all trades as well as the training/demonstration during the mockup performed by the air barrier installation crew to assure proper transitions and terminations. Construction is critical to the air barrier for scheduling, work sequence, protection from weather and other trades, and maintaining continuity of the air barrier, including at the inter- faces of the waterproofing, fenestration, penetrations, parapets, and roofs. Each of these processes are equilat- erally important to the performance of the air barrier and the attainment of the stated objective for the build- ing. e design should be established, critiqued with input from related trades, and executed with a verifi- cation plan to ensure that the end product meets the owner's perfor- mance requirements.
