3M™ Fire and Water & Smoke and Sound Tapes

Construction contractor holding new 3M™ Fire and Water Barrier Tape.
Now, There’s a Better Way.

Meet the new method that raises the standard.

Put down the sprayer and get to work with revolutionary, fast-installing 3M™ Fire and Water Barrier Tape and 3M™ Smoke and Sound Tape. They’re tested and listed with both UL and Intertek to ASTM E2307, E1966 and E814, and they meet the International Building Code. The only products on the market that use patent-pending 3M technology to provide instant fire, water, smoke and sound protection in convenient tape form. Use it on a variety of construction joints and through-penetration applications. No tools needed. No sprayers to clean or repair. No mess and less hassle.

  • Red 3M™ Fire and Water Barrier Tape in two different sizes.
    3M™ Fire and Water Barrier Tape

    Ideal for sealing perimeter joints (curtain wall joints) and other construction joints as well as some through-penetration applications. When installed properly (using mineral wool or backer rod if needed), this tape acts as a barrier to fire, water, smoke and sound.

  • Tan 3M™ Smoke and Sound Tape in two different sizes.
    3M™ Smoke and Sound Tape

    Ideal for providing a smoke and sound seal for construction joints and through-penetration applications in non-fire-rated wall and floor assemblies, including smoke partitions and acoustic assemblies. When installed properly, this material is used to provide a smoke seal to mitigate the spread of smoke and toxic gas as well as help reduce the transmission of sound (refer to installation instructions — may require mineral wool or backer rod to achieve STC ratings).

Fast and Easy Installation

Seals and protects in two simple steps.

  • 3M™ Fire and Water Barrier Tape unrolled and ready to use with clear markings.
    Step 1

    Select the type, size and amount of tape appropriate for your application. If needed, apply mineral wool or backer rod.

  • 3M™ Fire and Water Barrier Tape applied easily to a perimeter joint.
    Step 2

    Lay tape in place. Peel off release liner and adhere tape to surface — some creases, bubbles and wrinkles are okay.
