DEFINITIONS Air and Water Barrier Accessory: A transitional component of the air and water barrier that provides continuity. Air and Barrier Assembly: The collection of air and water barrier materials and accessories applied to an opaque wall, including joints and junctions to abutting construction, to control air and water movement through the wall. Factory Fluid-Applied Air and Water Barrier Panel: A glass mat-faced, moisture and gypsum panel. The panel features a non-combustible core integrated with a factory fluid-applied permeable air and water barrier membrane applied to the exterior/exposed side of the panel. Air and Water Barrier Material: A uniform factory fluid-applied primary element that provides a continuous barrier to the movement of air and water. ADMINISTRATIVE REQUIREMENTS Coordination: Coordinate installation of factory air and water barrier panel with framing installation and subsequent operations that impact finished envelope air-barrier work.
Seal punctures, and seams. Patch with membrane strips extending 6 inches (150 mm) beyond repaired areas. Connect and seal exterior wall air-barrier membrane continuously to subsequently installed roofing-membrane air-barrier, concrete below-grade structures, floor-to-floor construction, exterior glazing and window systems, glazed curtain-wall systems, storefront systems, exterior louvers, exterior door framing, and other construction used in exterior wall openings, using accessory materials. Wall Openings Transition Assembly Installation: Apply opening transition assembly so that a minimum of 3 inches (75 mm) of coverage is achieved over factory fluid-applied air and water barrier panels. Rough Openings: Treat rough openings with sealant or accessory products according to manufacturer installation instructions. Flashings: Seal top of through-wall flashings to factory air barrier air and water barrier panels with continuous transition strips of type recommended by sheet air barrier manufacturer for type of flashing. FIELD QUALITY CONTROL Testing Agency: Owner may engage a qualified testing agency to perform tests and inspections. Inspections: Air-barrier materials, accessories, and installation are subject to inspection for compliance with requirements and photo documentation of conditions to be concealed by subsequent Work. As determined by Owner's testing agency from among the following tests: Qualitative Air-Leakage Testing: Test air-barrier assemblies for evidence of air leakage according to ASTM E 1186, pencil with pressurization or depressurization or ASTM E 1186, chamber pressurization or depressurization with smoke tracers. Quantitative Air-Leakage Testing: Test air-barrier assemblies for air leakage according to ASTM E 783. Testing: Refer to Section [019113 “General Commissioning Requirements”] [019119.43 “Exterior Enclosure Commissioning"] for additional testing and inspection requirements. Factory fluid-applied air and water barrier panels will be considered defective if they do not pass tests and inspections. Prepare test and inspection reports.
