Air and Vapour Barrier is a film membrane that is impermeable to air, moisture, water and vapour. It is composed of an aggressive high-tack acrylic adhesive on a multi-layer elastomeric film that self-seals around screws, nails, and staples to further reduce moisture intrusion. 

3M™ Air and Vapour Barrier is compatible with a wide range of common sealants including synthetic rubber, butyl, polyurethane, silicone, and silane-terminated hybrid sealants. The adhesive sticks well to common construction substrates including concrete, concrete block, anodized aluminum, galvanized metal, plywood, extruded polystyrene, and most exterior gypsum sheathing. 

This allows for primer-free application from lightweight rolls and up to 40% faster installation compared to traditional air barriers that require a primer. The film is slightly translucent, providing a clean look while still allowing enough visibility to identify screws in the underlying sheathing and thus helps reduce the risk of the next contractor missing studs. 

This product can be applied at surface temperatures ranging from 0°F (-18°C) up to 150°F (66°C), has a service temperature range from -40°F (-40°C) up to 240°F (116°C), and can withstand up to 12 months of direct UV exposure.
