Description
3M™ Air and Vapor Through Wall Flashing Tape 3015 NP is a high-performance, self-adhered membrane designed for air, vapor and moisture control in commercial and residential building envelope applications.
Its pressure-sensitive adhesive provides strong adhesion to a wide range of common construction substrates and is designed to bond without the need for primer in many applications. The thin, flexible construction makes 3015 NP easy to detail around transitions, openings, penetrations and other critical areas of the building envelope.
Available in multiple widths, 3015 NP can be used for everything from smaller detail work to larger flashing and transition applications.

3M™ 3015 NP is a high-performance, self-adhered air and vapor barrier tape designed for building envelope detailing and flashing applications.
The 2-3/8" width is ideal for sealing narrower joints, seams, penetrations and transitions where a wider flashing membrane is not required. Its pressure-sensitive adhesive provides strong adhesion to many common construction substrates and allows primerless application in many conditions.
The thin, flexible construction makes 3015 NP easy to work with around detailed areas while helping maintain continuity of the air, vapor and weather barrier.
3M™ 3015 NP is a high-performance, self-adhered air and vapor barrier tape designed for building envelope detailing and flashing applications.
The 6" width provides wider coverage for window and door openings, transitions, penetrations, seams and other critical building envelope details. Its pressure-sensitive adhesive provides strong adhesion to many common construction substrates and allows primerless application in many conditions.
Its thin, flexible construction makes 3015 NP easy to install and conform around detailed areas while helping maintain continuity of the air, vapor and weather barrier.
3M™ 3015 NP is a high-performance, self-adhered air and vapor barrier tape designed for building envelope detailing and flashing applications.
The 4" width provides additional coverage for sealing joints, seams, window and door openings, penetrations and transitions. Its pressure-sensitive adhesive provides strong adhesion to many common construction substrates and allows primerless application in many conditions.
The thin, flexible construction makes 3015 NP easy to install and detail while helping maintain continuity of the air, vapor and weather barrier throughout the building envelope.
3M™ 3015 NP is a high-performance, self-adhered air and vapor barrier tape designed for building envelope detailing and flashing applications.
The 9" width provides substantial coverage for window and door openings, larger transitions, penetrations and other critical building envelope details. Its pressure-sensitive adhesive provides strong adhesion to many common construction substrates and allows primerless application in many conditions.
Its thin, flexible construction makes 3015 NP easy to install and conform around detailed areas while helping maintain continuity of the air, vapor and weather barrier.
3M™ 3015 NP is a high-performance, self-adhered air and vapor barrier membrane designed for building envelope detailing and flashing applications.
The 12" width provides broad coverage for window and door openings, large transitions, penetrations and other critical building envelope details. Its pressure-sensitive adhesive provides strong adhesion to many common construction substrates and allows primerless application in many conditions.
Its thin, flexible construction makes 3015 NP easy to install and conform around detailed areas while helping maintain continuity of the air, vapor and weather barrier.

3M™ Air and Vapour Barrier is an air, moisture, and water impermeable film membrane with an aggressive, high-tack pressure sensitive acrylic adhesive. It reduces air leakage and uncontrolled airflow from the building envelope, prevents moisture ingress and helps improve indoor air quality. It does not require the use of a primer on most construction surfaces.
