Vapour barriers

This 3015NP slit-liner air and vapour barrier membrane provides a continuous seal against air infiltration and moisture migration in wall and ceiling assemblies. The 2-7 slit liner configuration allows the membrane to conform around structural members during installation. Suitable for residential and commercial building envelope applications requiring a combined air and vapour control layer.

This 3015NP air and vapour barrier membrane features a 3-3 slit liner design for reliable control of air infiltration and moisture vapour transmission. Suited for residential and commercial building envelope applications, it creates a continuous barrier at wall assemblies, helping to improve energy efficiency and protect the structure from condensation damage.

This 3M 3015NP air and vapour barrier membrane features a 2-2 slit liner design for reliable installation on walls and assemblies requiring both air and moisture control. Suited for residential and light commercial construction, it provides a continuous barrier against air infiltration and vapour diffusion, helping maintain envelope performance and energy efficiency in new builds and renovations.

This 3015NP solid-liner air and vapour barrier membrane provides reliable protection against air infiltration and moisture migration in residential and commercial construction. Its white solid liner ensures consistent coverage across the full roll. Suitable for exterior wall assemblies, it helps maintain building envelope performance and supports energy efficiency by reducing uncontrolled air movement through the structure.

This 3M 3015NP air and vapour barrier membrane combines air-sealing and vapour control in a single solid-liner product. Finished in white, it installs as a continuous barrier against air infiltration and moisture diffusion in wall and ceiling assemblies. Its 2 3/8 in width makes it well suited for sealing joints, seams, and transitions in residential and light commercial building envelope applications.

This 3M 3015NP air and vapour barrier membrane features a 7-11 slit liner design and covers 18 in x 75 ft per roll. It provides a reliable air-sealing and moisture-control layer for walls, ceilings, and building envelope assemblies in residential and commercial construction. Suitable for new builds and renovation projects requiring code-compliant vapour management.

This 3M 3015TWF flashing tape is designed for air and vapour barrier applications at wall openings, including windows and doors. It forms a continuous, airtight and moisture-resistant seal at rough openings, sills, and jambs. The self-adhesive membrane bonds securely to wood, OSB, and common sheathing substrates, making it a dependable component in building envelope assemblies.
