<br />NON PERMEABLE AIR AND VAPOR BARRIERS 07 27 00 - 2
<br />B. Air Barrier Assembly Air Leakage: Not to exceed ASTM E 283.
<br />1.6 SUBMITTALS
<br />A. Product Data: Include manufacturer's written instructions for evaluating, preparing, and treating
<br />substrate; technical data; and tested physical and performance properties of air barrier.
<br />B. Shop Drawings: Show locations and extent of air barrier. Include details for substrate joints and cracks,
<br />counterflashing strip, penetrations, inside and outside corners, terminations, and tie-ins with adjoining
<br />construction.
<br />1. Include details of interfaces with other materials that form part of air barrier.
<br />2. Include details of mockups.
<br />C. Product Certificates: For air barriers, certifying compatibility of air barrier and accessory materials with
<br />Project materials that connect to or that come in contact with the barrier; signed by product manufacturer.
<br />D. Qualification Data: For Applicator.
<br />E. Product Test Reports: Based on evaluation of comprehensive tests performed by a qualified testing
<br />agency, for air barriers.
<br />1.7 QUALITY ASSURANCE
<br />A. Submit document stating the applicator of the primary air/vapor barrier membranes specified in this
<br />section is qualified by the manufacturer as suitable for the execution of the Work.
<br />B. Applicator Qualifications: A firm experienced in applying air barrier materials similar in material,
<br />design, and extent to those indicated for this Project, whose work has resulted in applications with a
<br />record of successful in-service performance and that is an ABAA-licensed contractor, employs
<br />certified and registered installers, and complies with ABAA's Quality Assurance Program.
<br />C. Components used shall be sourced from one manufacturer, including sheet membrane, air barrier
<br />sealants, primers, mastics, and adhesives.
<br />D. Single-Source Responsibility:
<br />1. Obtain air barrier materials from a single manufacturer regularly engaged in manufacturing the
<br />product.
<br />2. Provide products which comply with all state and local regulations controlling use of volatile
<br />organic compounds (VOCs).
<br />E. Mockups: Before beginning installation of air barrier, build mockups of exterior wall assembly
<br />incorporating backup wall construction, external cladding, window, door frame and sill, insulation, and
<br />flashing to demonstrate surface preparation, crack and joint treatment, and sealing of gaps, terminations,
<br />and penetrations of air barrier membrane.
<br />1. Coordinate construction of mockup to permit inspection by Owner's testing agency of air barrier
<br />before external insulation and cladding is installed.
<br />2. Include junction with roofing membrane, building corner condition, and foundation wall
<br />intersection.
<br />3. If Architect determines mockups do not comply with requirements, reconstruct mockups and
<br />apply air barrier until mockups are approved.
<br />4. Approved mockups may become part of the completed Work if undisturbed at time of Substantial
<br />Completion.
<br />F. Preinstallation Conference: Conduct conference at Project site.
<br />1. Include installers of other construction connecting to air barrier, including roofing, waterproofing,
<br />architectural precast concrete, masonry, sealants, windows, glazed curtain walls, and door frames.
<br />2. Review air barrier requirements including surface preparation, substrate condition and
<br />pretreatment, minimum substrate curing period, forecasted weather conditions, special details and
<br />sheet flashings, mockups, installation procedures, sequence of installation, testing and inspecting
<br />procedures, and protection and repairs.
