The 3M™ Smoke and Sound Tape is an elastomeric tape that can act as a barrier to smoke and airborne sound non-fire-rated wall and floor assemblies.
Our 3M™ Smoke and Sound Tape provides a smoke and sound barrier by minimizing smoke and sound transfer between rooms and floors when installed in a variety of construction joints and through penetrations. Smoke and Sound Tape carries an “L” rating and has been tested to ASTM E 90 and ASTM E 413 – achieving an STC-Rating of 54 when tested in an STC 54-rated wall assembly.

The elastomeric material maintains performance with up to +/- 50% movement capabilities. It has a high tack adhesive that sticks to most common building materials and exceeds the AAMA 711 minimum for adhesion in peel. In addition, it can be installed in temperatures as low as 0°F (18°C) and has high as 120°F (49°C). Its unique adhesive adheres to damp surfaces and meets the intent of LEED® VOC environmental guidelines. The tape complies with the current requirements of the International Building Code (IBC). NFPA 5000 and NFPA 101.
