SECTION 07 27 26 FLUID-APPLIED MEMBRANE AIR BARRIER Specifier Note: This guide specification is written according to the Construction Specifications Canada (CSC) Format. The section must be carefully reviewed and edited by the Architect or Engineer to meet the requirements of the project. Coordinate this section with other specification sections and the drawings. GENERAL SECTION INCLUDES Fluid-applied membrane air barrier located in the non-accessible part of the wall. Materials to bridge and seal the following air leakage pathways and gaps: Connections of the walls to the roof air barrier. Connections of the to the foundation air barrier. Seismic and expansion joints. Openings and penetrations of window frames, storefront, curtain wall. Barrier precast concrete and other envelope systems. Door frames. Piping, conduit, duct and similar penetrations. Masonry ties, screws, bolts and similar penetrations. All other air leakage pathways in the building envelope. Specifier Note: Coordinate related work requirements with contents of referenced specification sections. Section [014000] [Quality Requirements; coordination with Owner’s independent testing and inspection agency.] Section [014339] [Mock-Ups; exterior wall mock-ups.] Section [015000] [Temporary Facilities and Controls; requirement to schedule work to prevent sunlight and weather exposure of materials beyond limits established by manufacturer; requirement to protect materials from damage after installation and prior to installation of enclosing work.]
Shop Drawings: Submit Shop Drawings showing locations and extent of air barrier assemblies and details of all typical conditions, intersections with other envelope assemblies and materials, membrane counter-flashings, and details showing how gaps in the construction will be bridged, how inside and outside corners are negotiated, how materials that cover the materials are secured with condition maintained, and how miscellaneous penetrations such as conduits, pipes, electric boxes and similar items are sealed. Include VOC content of each material, and applicable legal limit in the jurisdiction of the project. Include required values for field adhesion test on each substrate. Air Barrier Subcontractor Qualifications: Air barrier Subcontractor(s) shall be accredited at the time of bidding and during the complete installation period by the National Air Barrier Association (NABA) whose Installer(s) are certified in accordance with the site Quality Assurance Program used by NABA. Fluid-Applied Membrane Air Barrier Installer(s) shall be certified by BPQI (Building Performance Quality Institute) for the NABA Quality Assurance Program in accordance with the requirements outlined in the QAP program used by NABA. Installers shall have their photo identification air barrier certification cards in their possession and available on the project site, for inspection upon request. Manufacturer: Obtain primary NABA Evaluated Materials from a single NABA Listed Manufacturer regularly engaged in manufacturing specified fluid-applied membranes. Obtain secondary materials from a source acceptable to the primary materials manufacturer. Accredited Laboratory Testing for Materials: Laboratory accredited by International Accreditation Service Inc. (IAS), American Association for Laboratory Accreditation (A2LA), or the Standards Council of Canada (SCC). VOC Regulations: Provide products which comply with applicable regulations controlling the use of volatile organic compounds. Field Quality Assurance: Implement the site Quality Assurance Program requirements used by NABA. Cooperate with NABA Auditors and any independent testing and inspection agencies engaged by the Owner. Do not cover the air barrier assembly until it has been inspected, tested and accepted. Air Barrier Assembly Testing: Verify air barrier assembly testing by the material manufacturer by visiting the NABA website to ensure a ASTM E2357 test has been completed and to obtain results.
