          1.Install transition strips, and auxiliary materials according to air barrier manufacturer's written instructions to form a seal with adjacent construction and maintain a continuous air barrier.
          a.Coordinate installation of air/vapor barrier with installation of roofing membrane and base flashing to ensure continuity of air/vapor barrier with roofing membrane.
          ** NOTE TO SPECIFIER ** Select appropriate type of strip below.
          b.Install transition strip on roofing membrane or base flashing so a minimum of 3 inch (76 mm) of coverage is achieved over both substrates.
 
          B.Foam Sealant: Fill gaps in perimeter frame surfaces of windows, curtain walls, storefronts, and doors, and miscellaneous penetrations of air/vapor barrier membrane with foam sealant.
          ** NOTE TO SPECIFIER ** Select appropriate product for sealing air/vapor barrier terminations below.
 
          C.Wall Openings: Apply transition strip so that a minimum of 3 inch (76 mm) of coverage is achieved over both substrates. Maintain 3 inch (76 mm) of full contact over firm bearing to perimeter frames with not less than 1 inch (25 mm) of full contact. Roll firmly to enhance adhesion, with steel flooring seam roller.
          ** NOTE TO SPECIFIER ** Coordinate Paragraph below with Drawings.
 
          D.Connect and seal exterior wall air/vapor barrier membrane continuously to roofing membrane air/vapor 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 as specified, as indicated, or both.
 
          E.Terminate top of wall flashing with flashing manufacturer's termination bar and flashing sealant at top of termination bar. Seal all screw heads.
 
          F.Seal exposed edges of strips at seams, cuts, penetrations, and terminations not concealed by metal counterflashing's or ending in reglets with termination mastic.
 
          G.Repair punctures, voids, and deficient lapped seams in strips and transition strips. Slit and flatten fishmouths and blisters. Patch with transition strips extending 6 inch (152 mm) beyond repaired areas in strip direction.
 
          H.At end of each working day, seal top edge of transition strips to substrate with termination mastic.
 
          I.Joint Sealant: Apply joint sealants forming part of air/vapor barrier assembly within manufacturer's recommended application temperature ranges. Consult manufacturer when sealant cannot be applied within these temperature ranges.
 
          J.Air/Vapor Barrier Membrane Installation:
          1.Apply air/vapor barrier membrane to form a seal with strips and transition strips and to achieve a continuous air/vapor barrier according to air/vapor barrier manufacturer's written instructions.
          2.Apply air/vapor barrier membrane within manufacturer's recommended application temperature ranges.
          3.Apply a continuous unbroken air/vapor barrier to substrates according to the following minimum thickness. Apply membrane in full contact around protrusions such as masonry ties.
          ** NOTE TO SPECIFIER ** Verify minimum thickness recommended by manufacturer; recommended thickness may vary with substrate.
          a.Vapor Retarding Membrane Air/Vapor Barrier: 40 to 45 mils (1.016 to 1.143 mm) wet film thickness, and 23 to 28 mils (0.584 to 0.711 mm) dry film thickness.
          4.Apply strip and transition strip over cured air membrane overlapping 3 inch (76 mm) onto each surface according to air barrier manufacturer's written instructions.
          5.Do not conceal air barrier until it has been tested and inspected by Owner's testing agency.
          6.Correct deficiencies in or remove air/vapor barrier that does not comply with requirements; repair substrates and reapply air/vapor barrier components.
 
          3.5FIELD QUALITY CONTROL
          ** NOTE TO SPECIFIER ** Coordinate test and inspection requirements in this Article, with Section 01 45 23, with input from Owner's testing agency.
 
          A.Testing and Inspection Services shall be performed by qualified parties as specified herein, and in accordance with the sections in Division 01.
 
          B.Testing Agency: Owner will engage a qualified testing agency to perform tests and inspections and prepare test reports.
 
          C.Inspections: Air/vapor barrier materials and installation are subject to inspection for compliance with requirements. Inspections include the following:
          ** NOTE TO SPECIFIER ** Delete list of inspections below as required for Contractor's information.
          1.Continuity:
          a.Air/vapor barrier system has been achieved throughout the building envelope with no gaps or holes.
          b.Continuous structural support of air/vapor barrier system has been provided.
          2.Preparation:
          a.Masonry and concrete surfaces are smooth, clean and free of cavities, protrusions, and mortar droppings.
          b.Masonry and concrete surfaces are cured.
          c.Compatible materials have been used.
          3.Site conditions:
          a.Application temperature and preparation of substrates have been maintained.
          b.Maximum exposure time of materials to UV deterioration has not been exceeded.
          4.Transitions, Penetrations, Terminations:
          a.Laps in strips and transition membranes have complied with minimum requirements and have been shingled in the correct direction (or liquid membrane has been applied on exposed edges), with no fishmouths.
          b.Membrane support at changes in direction and gaps have been provided.
