BarrierMembrane3015
PRODUCTDESCRIPTION:3M™Self-AdheredAirandVaporBarrierMembrane3015isahighperformance, vaporimpermeable,self-adheredmembranepossessinggoodadhesion,elongationandself-sealingproperties that make it ideal for use as a secondary barrier behind exterior cladding systems. The membrane material
is a proprietary film developed by 3M that is unlike any other existing weather/secondary barrier product. The adhesive contains no asphalt or butyl. Only one membrane material is needed for both the field barrier and for penetration flashing; its unique elastic and adhesive qualities make it an ideal self-adhered flexible
flashing material at penetrations as well as for sealing around openings for doors and windows.
NOTE TO DESIGNER – VAPOR BARRIER: 3M™ Self-Adhered Air and Vapor Barrier Membrane 3015 is a Class II vapor retarder with a water vapor permeance of less than 1 perm (per ASTM E-96). In order to allow the use of the generic term “barrier” to be applied to the various functions of this product (air/water/vapor barrier) it is referred to throughout this specification as a “vapor barrier”. Proper placement of a vapor barrier within any assembly requires an understanding of vapor diffusion and condensation dynamics; it is recommended that a hygrothermal analysis of the assembly be performed by the designer based on the climate conditions found at the building location so as to avoid moisture problems within the assembly due to condensation and/or trapped moisture.
NOTE TO SPECIFIER: 3M™ Self-Adhered Air and Vapor Barrier Membrane 3015 can be specified as a CSI
2004 MasterFormat Specifications Group titled Division 07 25 00 - Weather Barriers, or as a CSI 2004

3.02PREPARATION
A.To obtain the best adhesion, 3M™ Self-Adhered Air and Vapor Barrier Membrane 3015 should be installed when outdoor temperatures are above 0°F (-18°C)
1.Surfaces must be clean, free from dirt and debris and not have absorbed water.
2.Surfaces must be free of any damaged, unsupported areas, sharp protrusions or voids.
3.Concrete must be cured a minimum of 28 days before application.
4.Block or brick walls must have mortar joints stuck flush.
5.While 3M™ Self-Adhered Air and Vapor Barrier Membrane 3015 can be applied as low as 0°F (-18°C), surfaces must be clear of snow, ice or frost.
6.3M™ Self-Adhered Air and Vapor Barrier Membrane 3015 adheres to most common building materials. For difficult to stick to surfaces, test adhesion before application. If needed, apply 3M™ Hi-Strength 90, 3M™ Hi-Strength 94 ET Spray Adhesive, 3M™ Scotch-Weld™ Holdfast 70, or 3M™ Fastbond™ Contact Adhesive 30NF to prime the substrate prior to applying the membrane.
B.Gaps/Cracks In Substrate Surface Exceeding 1/4 inch (6.35 mm) width: Fill gap/crack with 3M™ Polyurethane Sealant 540 and tool surface flush and smooth.
1.See 3M™ Polyurethane Sealant 540 technical data sheet for use and limitations of sealant application.
C.Penetrations Of Barrier System: Fill gaps/cracks exceeding 1/4 inch (6.35 mm) width between the substrate and the item penetrating the barrier system with 3M™ Polyurethane Sealant 540
1.See 3M™ Polyurethane Sealant 540 technical data sheet for use and limitations of sealant application.
3.03BARRIER SYSTEM INSTALLATION
NOTE TO SPECIFIER: Delete the type(s) of barrier system listed below in [brackets] that are not applicable to project.
A.Install barrier system in accordance with 3M Installation Instructions in locations shown on the
Drawings to provide a continuous [water-resistive barrier] [air barrier] [air/water/vapor barrier].
1.3M™ Self-Adhered Air and Vapor Barrier Membrane 3015 must be lapped a minimum of 2 inches (50.8 mm) on sides and ends.
2.Inside and outside vertical corners must be lapped a minimum 6 inches (152 mm).
3.Cut membrane to desired length and wind up into a roll for easy handling. Fold the starting edge back over itself to crease the paper release liner. Peel back the liner to expose a starting 2-3 inch (50.8-76.2 mm) adhesive strip.
4.3M™ Self-Adhered Air and Vapor Barrier Membrane 3015 is ready to apply as soon as the release liner is removed. The adhesive is very aggressive and quickly bonds to substrates. Do not contaminate the starting strip with dust or debris before applying it to the intended surface. Be careful when aligning product on the wall as repositioning may be challenging.
5.Once aligned, set the membrane in place by rolling the product back against the exposed adhesive. Unwind the roll while simultaneously pulling the release liner, maintaining pressure against the wall to tack the membrane in place. Wipe the membrane down with a feathering motion from the middle outward to obtain a smooth surface.
6.For best air barrier membrane performance, roll the membrane with a rubber roller to ensure a tight seal against the wall and between overlapped edges.
7.It is recommended to seal the leading edge of the membrane at the end of each work day with 3M™ Polyurethane Sealant 540. Smooth the bead to the surface to avoid creating a projecting obstruction when the next layer of membrane is overlapped.
8.Detail work must be carefully executed to ensure a continuously sealed building envelope.
9.See 3M™ Self-Adhered Air and Vapor Barrier Membrane 3015 Product Guide for detail drawings.
B.Windows and Rough Openings
1.Wrap rough openings with 3M™ Self-Adhered Air and Vapor Barrier Membrane 3015.
2.When working with product, align and position membrane, remove release liner and press firmly into place. Roll all laps and membrane with a rubber roller to ensure optimum seal.
3.Apply detail strips of membrane in each sill corner extending the full depth of the sill and a minimum 2 inches (50.8 mm) to the jamb, sill and face.
Apply appropriate lengths of membrane to form sill and dams, then along the jambs and at the head.
4.Install membrane in “weatherboard” or “shingle fashion” with 2 inch (50.8 mm) overlap at all end and side laps of membrane, and extending a minimum 2 inches (50.8 mm) from the opening to the face of the exterior wall.
5.See 3M™ Self-Adhered Air and Vapor Barrier Membrane 3015 Product Guide for detail drawings.
C.Penetrations:
1.Seal all penetrations 3M™ Polyurethane Sealant 540. Install 3M™ Self-Adhered Air and Vapor Barrier Membrane 3015 material cut to length to allow installation around the full circumference of the item penetrating the barrier system and ensure a continuous
airtight seal.
a.See 3M™ Polyurethane Sealant 540 technical data sheet for use and limitations of sealant application.
2.Knife Plate / Masonry Tie:
a.Cut an appropriately sized square of membrane to overlap the knife plate a minimum 2 inches (50.8 mm) in each direction.
b.Cut a slot within the piece and apply over the knife plate.
c.Apply 3M™ Polyurethane Sealant 540 where knife plate penetrates the barrier. d. See 3M™ Self-Adhered Air and Vapor Barrier Membrane 3015 Product Guide
for detail drawings.
3.Vent/Pipe penetrations:
a.Apply 3M™ Polyurethane Sealant 540 between the penetration and the exterior wall.
b.Apply membrane to allow continuous 2 inch (50.8 mm) overlap onto vent/pipe penetration and cut “fingers” to transition to the exterior wall.
c.See 3M™ Self-Adhered Air and Vapor Barrier Membrane 3015 Product Guide for detail drawings.
