Sound Barrier Tape for Seams and Gaps: MLV Tape

To soundproof a room effectively, all seams and gaps must be sealed. Think of the room as a fish bowl, if there is a crack or hole in the bowl, water will get out. It is the same with soundproofing a wall or room. If there is a way for sound to get through that wall, either a crack, a hole, or a gap, the sound will get through!
By employing MLV Tape, sound will not be able to leave or penetrate a room. The tape is engineered from our MLV material. It is 1/16” thick and is easy to work with.

Why Use MLV Tape in Your Soundproofing Project?

MLV tape streamlines installation by providing a fast, mess‑free way to seal seams, saving labor time compared with acoustic caulks or other wet adhesives. It also shields exposed vinyl edges from dust and humidity, preserving the assembly’s clean appearance and long‑term durability.

Improves Sound Blocking

By creating a tight seal around the edges and seams of mass loaded vinyl, MLV Tape ensures that airborne noise doesn’t sneak through small gaps or overlaps. The result? A quieter, more controlled acoustic environment.

Prevents Material Shifting

Over time, vibrations and everyday wear can cause MLV sheets to shift or loosen. MLV Tape keeps the vinyl in place, preserving the integrity of your soundproofing installation.
