Neoprene 1/2" x 6" x 25' Isolation Gasket PSA

This USA-made neoprene adhesive foam tape is ideal for sound isolation in any room where exterior noise poses a problem. It's used for isolating ceilings and walls, sealing along doors and windows, isolating joists and studs, and sealing small gaps on ceilings, floors and walls. This is an easy-to-install, affordable means for providing soundproofing in a room where impact noise is a problem. The pressure-sensitive adhesive readily sticks to all types of materials, including drywall, wood, gypcrete, sound board and more.

We offer some great neoprene sound gasket in rolls in lengths of 25' or 50' and widths of 1/2”, 1”, 3-1/2”, 6”, 8” and 12”. This is closed-cell neoprene gasket tape with peel-off PSA (pressure-sensitive adhesive) available in thicknesses of 1/8”, 1/4” and 1/2”.

Applications:

Wall and ceiling isolation
Perimeter isolation and seal along windows or doors
Seal small gaps on walls, floor, ceiling
Isolate studs, joists

When your project demands the highest level of noise and vibration control, you need to escalate your approach with a more robust solution. SoundAway’s heavy-duty Neoprene Isolation Gasket is engineered for these exact challenges. With a substantial 1/2" thickness and an extra-wide 6" profile, this product delivers maximum isolation for the most demanding applications, going far beyond standard wall assemblies. This is the ultimate sound-dampening material when you need to stop powerful, low-frequency vibrations in their tracks.

The power of this gasket lies in its impressive dimensions. The half-inch-thick, closed-cell soundproofing foam provides a thick, resilient cushion that absorbs and dissipates intense vibrational energy. You can use this versatile foam tape to create a sill plate gasket, isolating entire wall structures from the foundation to prevent noise transfer from floor to floor. Its 6-inch width makes. When combined with other soundproof insulation materials, you create a comprehensive and formidable barrier against noise.

Unlike lighter acoustic foam designed for airborne sound, this dense neoprene is a specialized tool for structural isolation. As one of the most effective soundproofing products for vibration, its peel-and-stick backing ensures a simple, secure installation, creating a floating effect for floors, walls, and equipment. If you're serious about creating a truly isolated space, this heavy-duty soundproofing foam is an indispensable part of your toolkit. Don't let structural vibrations compromise your investment in other Soundproofing materials; stop them at the source.

Heavy-Duty Vibration Isolation: Features a substantial 1/2" thickness, providing maximum dampening and shock absorption for machinery, HVAC units, and home theater subwoofers.
Extra-Wide for Versatile Applications: The 6-inch width is perfectly suited for use as a sill plate gasket to decouple walls from foundations
Superior Decoupling Performance: This dense, closed-cell neoprene foam creates an exceptional physical break, making it a critical component for building floating floors and achieving professional-level sound isolation.
