2 Controlling air is crucial for health & energy efficiency of buildings Air barriers are essential elements of new building construction. Air naturally moves from warm to cold areas, and moisture moves from humid to dry areas. In walls without air barriers, uncontrolled movement can result in condensation of moisture on cold surfaces, as shown in the illustrations below. Uncontrolled flow of air and moisture can harm the long-term performance and durability of your building materials, decrease indoor air quality, lower energy efficiency, and literally affect the health of your building and its occupants. Northern Climates Southern Climates Air Flow Air Flow WARM TO COLD COLD TO WARM INTERIOR EXTERIOR INTERIOR EXTERIOR Moisture Condensation Moisture Condensation HUMID TO DRY DRY TO HUMID Vapor Diffusion Vapor Diffusion 1 2 In northern climates, warm, humid air moves naturally from building interiors to colder, drier exteriors. Without air barriers, moisture will condense on the colder, inside surface of the exterior wall. In southern climates, warm, humid air moves naturally from building exteriors to cooler, drier interior areas. Without air barriers, moisture will condense on the colder, inside surface of the interior wall. Uncontrolled air flow can be a major problem, especially in cold-weather climates 2 It s been estimated that over the course of a heating season about 1/3 of a quart of water can pass directly through gypsum board without a vapor retarder, and that 30 quarts of water can pass through the same gypsum wall with just a 1" x 1" whole in that same time period. 1 1 Builder s Guide to Cold Climates, Joseph Lstiburek 4'x 8' sheet of gypsum board interior at 70 F & 40% RH Vapor diffusion through solid board = 1/3 quart of water over the course of one heating season Diffusion vs. Air Leakage 3 1"x 1" whole 4 x 8 sheet of gypsum board interior at 70 F & 40% RH Air leakage = Up to 30 quarts of water over the course of one heating season

3 Air barriers help solve some of the biggest environmental challenges Modern buildings are affected by a multitude of environmental challenges that can significantly affect their performance. Wind pressure. The forces of wind on a building can be broken down into two categories: Positive (windward) pressure tries to push air into the building and negative (leeward) pressure tries to draw air out of the building, most commonly through gaps and openings within the structure. Fan pressurization. Mechanical (HVAC) systems are designed to create air movement within a building. The supply side of the system creates positive pressure that delivers conditioned air to the desired locations, while the return side and exhaust vents recycle and remove air, creating a negative pressure. These systems must be balanced in order to perform properly. Stack pressure. Air density is related to air temperature. As air temperature warms, it becomes lighter and rises. The opposite is also true: As air temperature cools, it becomes denser and falls. A classic example of this is a hot air balloon. Barometric cycling. Air pressure changes due to the weather. High pressure is associated with nice weather while low pressure is associated with inclement weather. This is typically not an issue inside buildings except when there are rapid pressure drops, such as those that can result in tornadoes. Then the rapid pressure changes between the interior and exterior can cause windows to blow out, as the building pressure tries to balance itself with the ambient conditions. Thermal cycling. All construction materials shrink with cold and expand with heat over the 24-hour period from the cool of the night to the heat of the day. Materials are either extracting or emitting heat or cold, which causes the building HVAC system to respond in order to maintain the desired temperature.

4 How to choose the right air barrier system Depending on their material characteristics, air barriers can control or block the passage of water vapor. There are three main types of moisture-control systems: Rain/liquid barriers. Typically, these are mechanically attached sheet systems that are not designed to limit air, but rather act as a rain or water screen. Air barriers. Air barriers are permeable systems that allow vapor transmission through a wall assembly. These barriers are available in both sheet- and sprayapplied membranes. The perm rating is typically greater than 10. Air and vapor barriers. These nonpermeable systems stop air and moisture transmission through the wall assembly. They typically have a perm rating of less than 1.0 ( perm rating is a measure of the diffusion of water vapor through a material). Choosing the right air barrier system is a function of the kind of wall assembly you re constructing (the primary driver), your climate location (secondary driver), and your goals for sustainable construction. Once you ve selected a wall assembly design, the application temperature and relative humidity of your climate will determine the best barrier type. For example, cold or wet weather may eliminate some coatings and sheet membrane systems. Maximize your building efficiency Protecting buildings with a continuous 3M Air Barrier System provides a wide range of positive benefits, including: Better indoor air quality Reduced construction and operating costs of your HVAC by enabling smaller, more efficient equipment Less risk of mold and mildew Happier, healthier residents Extended service life and durability of your building Energy savings through the reduction of unintended air movement An air barrier system is designed to be a sheet or spray-applied membrane. It s designed to control the unintended movement of air flow into and out of the building enclosure. 5 4B 1A 3M Air and Vapor Barrier B 3M Air Barrier 3015VP 3 1A 2 3M Through Wall Flashing Tape 3015TWF 3 3M Scotch-Weld HoldFast 70 Cylinder Spray Adhesive 4A Continuous Insulation 4A Exterior Gypsum Sheathing 1B 4B Fiberglass batt insulation 2 5 Closed-cell foam insulation or approved sealant Vapor Diffusion Air Leakage 4A 3 4

Installation Best Practices Substrate Information and Surface Preparation 3M Air and Vapor Barrier 3015 can be applied to a wide variety of sheathing substrates, typically without priming. Substrate condition is crucial to the adhesion performance of any adhesive membrane. Substrate surfaces must be free of grease, oil, unbonded paint, corrosion, or other substances that would adversely affect the adhesive bond between the membrane and substrate. For optimum performance, substrate surface must be dry to the touch with the ambient temperature above 0 F (-18 C). Additionally, consider the following for success with specific surfaces: Exterior gypsum sheathing shall have moisture content below 19% with no open joints or cracks wider than ½ inch. Plywood substrates shall have moisture content below 16% with no open joints or cracks wider than ½ inch. Concrete surfaces shall have fins ground flush and void areas filled. Masonry substrates must have mortar joints struck flush. Fill gaps and cracks exceeding ¼" width with 3M Polyurethane Sealant 540, and tool the surface flush and smooth. Fill gaps exceeding ½" width with closed cell foam backer rod, seal with 3M Polyurethane Sealant 540, and tool the surface flush and smooth. Needed Supplies 3M Air and Vapor Barrier M Polyurethane Sealant 540 Extended blade razor knife J Roller Installation Layout Planning To minimize waste, plan the layout prior to application of 3M Air and Vapor Barrier Particular attention should be given to penetrations where weather exposure and tight installation is critical. Detailing window and door penetrations is recommended before applying the membrane, but if necessary, the membrane can be applied after detailing. 1

11 Application Techniques Install 3M Air and Vapor Barrier 3015 vertically or horizontally. During installation, keep membrane dry and protect from dust and debris. For easier handling, pre-cut membrane into individual manageable lengths. Simply pull the material off the main roll to the desired length then cut the square to the factory edges using a razor knife. Wall Application While the membrane may be applied horizontally or vertically, horizontal installation is preferred. Best practice includes a weatherboard or shingle fashion, starting with the first strip of membrane across the bottom of the wall. Moving up the wall, the next strip higher will overlap the lower previous strip by 2 inches. Buildings are designed to accommodate thermal and seismic movement. To accommodate floor-line movement, limit strip coverage within a single floor area, allowing overlaps at the floor lines. Vertical seams should be staggered from floor to floor, or separated by a horizontally applied strip of 3M Air and Vapor Barrier Minimum overlap on sides and ends is 2 inches. On inside and outside vertical corners, the minimum overlap is 6 inches. 2

12 Application Techniques To start: 1. Cut material to desired length 2. Wind up into a roll for easy handling 3. Fold the starting edge back over itself to crease the paper release liner 4. Peel back the liner to expose a starting 2-3 inch adhesive strip 5. Keep clean do not contaminate the starting strip with dust or debris before applying it to the intended surface. 3M Air and Vapor Barrier 3015 is ready to apply as soon as the release liner is peeled back. Be careful when aligning product on the wall as repositioning may be challenging. The adhesive is very aggressive and quickly bonds to substrates. Once aligned, set the membrane in place by rolling the product back against the exposed adhesive. Wipe the membrane down with a feathering motion from the middle outward to obtain a smooth surface. Unwind the roll while simultaneously pulling the release liner, maintaining pressure against the wall to tack the membrane in place. Penetration Areas 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. Best practice methods recommend sealing the leading edge of the membrane at the end of each work day. 3M recommends the use of 3M Polyurethane Sealant 540 if you do this. Smooth the bead to the surface to avoid creating a projecting obstruction when the next layer of membrane is overlapped. Window and door penetrations can be detailed pre- or post-installation of the membrane. Pre-installation, however, is recommended. All penetrations, including windows and doors, must be installed in proper sequence for appropriate moisture management. Use either 3M Air and Vapor Barrier 3015 for flashing and detail work. Penetrations should be additionally sealed with a sealant like 3M Polyurethane Sealant 540 to achieve a weather-tight result. 3

13 Application Techniques Rough Openings (Windows and Doors) When working with 3M Air and Vapor Barrier 3015, always install membrane in weatherboard or shingle fashion. Begin by pre-cutting membrane into appropriate size, align and position the membrane, remove release liner, and press firmly into place. Roll all laps and membrane with a rubber roller to ensure optimum seal. Follow these steps: 3M 3015 fold into opening to form sill and dams Apply 3M 3015 on jambs extending 4" from opening fold into opening and shingle lap over sill wrap 1. Apply appropriately sized piece to the bottom of the opening, folding into the opening to form sill and dams. Ensure a 2" overlap to the exterior face. 3. Apply appropriately sized pieces on the jambs, extending 4" from the opening to the exterior face. Fold the membrane into the opening and shingle lap over the previously applied sill wrap. Apply 3M 3015 at head extending 4" from opening, fold into opening and shingle lap over jamb wrap 2. Apply detail strips of membrane in each sill corner extending the full depth of the sill and a minimum 2" to the jamb, sill, and face Apply appropriately sized piece at the head, extending the membrane 4" from the opening to the exterior face. Fold the membrane into the opening and shingle lap over the jamb wrap.

14 Application Techniques Vent and Pipe Penetrations Masonry (Brick) Tie/Knife Plate Sheathing Sheathing Apply sealant around penetration Apply sealant around knife plate 1. Apply 3M Polyurethane Sealant 540 in the gap between the penetration and the exterior wall. 1. Apply 3M Polyurethane Sealant 540 where knife plate penetrates the membrane. Sheathing Sheathing Apply membrane to penetration with fingers adhered to sheathing Cut a slot in a piece of membrane and apply over knife plate to extend a minimum 2" in each direction 2. Apply membrane to allow continuous 2" overlap onto vent/pipe penetration and cut fingers to transition to the exterior wall. 2. Cut a square of membrane that overlaps the knife plate a minimum 2" in each direction. Cut a slot in the center of the square to slip membrane over the knife plate. 5

15 Application Techniques Junction Box 1. Apply 3M Polyurethane Sealant 540 around junction box. 3. Perpendicular to the direction of the wrap, cut four fingers so that the membrane can transition down from the box to the exterior wall.

Adhesive provides a unique combination of both cold and hot temperature adhesion to most substrates, which can extend the construction season in many climates. Unique adhesive even adheres to damp surfaces that have not absorbed water, like metals, glass and plastics. Seals around nails and staples to prevent moisture intrusion. Surface Preparation To obtain the best adhesion, 3M Air Barrier 3015VP should be installed when outdoor temperatures range from 0 F (-18 C) to 150 F (66 C). Surfaces should be clean, free from dirt and debris and have not absorbed water. Surfaces should be free of any damaged, unsupported areas, sharp protrusions or voids. Concrete must be cured a minimum of 7 days before application. Block or brick walls should have mortar joints stuck flush. While it can be applied as low as 0 F (-18 C), surfaces must be clear of snow, ice or frost. Adheres to most common building materials. For difficult to stick to surfaces, test adhesion before application. If needed, apply 3M Hi- Strength 90 Spray Adhesive, 3M Hi-Strength 94 ET Spray Adhesive, 3M Holdfast 70 Spray Adhesive or 3M Fastbond Contact Adhesive 30NF to prime the substrate prior to applying the membrane. Products are available as either an aerosol or cylinder spray adhesive. 2

28 3M Air Barrier 3015VP Application Instructions Refer to 3M Air Barrier 3015VP Specification Guide for detailed application information. Remove outer protective film to expose adhesive surface. Must be lapped a minimum of 2" on sides and ends. Remove protective film cover before installing the next layer. No primer is needed on most construction surfaces. The adhesive is very aggressive and quickly bonds to substrates. Do not contaminate the adhesive area with dust or debris before applying it to the intended surface. Be careful when aligning product on the wall as repositioning may be challenging. Once aligned, set the membrane in place by rolling the product back against the exposed adhesive. Unwind the roll while 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. 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. Remove film covering membrane. Detail work must be carefully executed to ensure a continuously sealed building envelope. Rough openings may be flashed with detail widths of 3M Air and Vapor Barrier

33 Self-Adhered Air and Vapor Barrier Membrane 3015 Building Envelope Solutions Statements of Material Compatibility Technical Bulletin May, 2013 Introduction Limitations 3M Self-Adhered Air and Vapor Barrier Membrane 3015 features an aggressive, nonstaining, high tack acrylic pressure sensitive adhesive that does not require the use of a primer on most construction surfaces. The membrane is compatible with many building sealants: There is no adverse reaction with synthetic rubber, butyl, polyurethane, silicone and silane terminated hybrid sealants. 3M Self-Adhered Air and Vapor Barrier Membrane 3015 has excellent adhesion to concrete, concrete block, anodized aluminum, galvanized metal, plywood, extruded polystyrene and most exterior gypsum sheathing without the use of primer. 3M Self-Adhered Air and Vapor Barrier Membrane 3015 is not compatible with flexible vinyl membranes such as PVC roofing membrane. However, rigid PVC pipe or window trim are acceptable substrates. 3M Self-Adhered Air and Vapor Barrier Membrane 3015 bonds well to the smooth side of OSB panels but a primer may be necessary if the membrane is being applied to the waffle side of the board. 3M Self-Adhered Air and Vapor Barrier Membrane 3015 bonds well with no primers or additional adhesives to Georgia Pacific DensGlass Sheathing, USG Securock Sheathing and National Gypsum Gold Bond exp Extended Exposure. A primer may be necessary when bonding to CertainTeed GlasRoc Sheathing. 3M Self-Adhered Air and Vapor Barrier Membrane 3015 will discolor when placed in contact with any self adhered membrane with a PE (polyethylene) backing and bitumen adhesive. Accelerated aging testing indicates the bond between the products is not adversely affected by the discoloration. No discoloration occurs between the foil surface of a foil backed bitumen based membrane and 3M 3015, although there is discoloration at the end of the overlap where the bitumen adhesive is directly exposed to 3M 3015 membrane. 3M Self-Adhered Air and Vapor Barrier Membrane 3015 has been shown to bond well to certain types of EPDM or TPO membranes. See Technical Bulletin , Adhesion to Roofing Membranes, for more information. Samples should be submitted for evaluation for specific projects. Primer If required, an installer has several options for primers that are compatible with 3M Self-Adhered Air and Vapor Barrier Membrane 3015: 3M Scotch-Weld Holdfast 70 is packaged in pressurized cylinders and is very convenient when large surface areas need to be covered. 3M Hi-Strength 90 or 3M Hi-Strength 94 ET Spray Adhesive are packaged in aerosol cans and are convenient for small areas. 3M Fastbond Contact Adhesive 30NF is packaged in pressurized cylinders, cans or pails for use when a waterbased primer is desired.
