AlphaSorb® Barrier Acoustic Panels

(4 customer reviews)

The AlphaSorb® Barrier Fabric Wrapped Wall Panels offers the sound absorption value of standard wall panels combined with the soundproofing capabilities of our AudioSeal® Sound Barrier.  This is achieved with the addition of the sound barrier septum between the two layers of fiberglass.  These panels are used to improve the acoustics within a room as well as block the transmission of sound to adjacent spaces.

For this product to be effective in blocking sound, the whole wall needs to be covered from floor to ceiling. The AlphaSorb® Barrier Fabric Wrapped Wall Panels allow you to add a sound blocking material without having to reconstruct your wall assembly. Ideal for applications that require speech privacy or need to block sound.

AlphaSorb® Barrier Panels may be cut to fit on site or ordered in custom sizes. Also note that electrical boxes will need to be extended to compensate for the added thickness of the panel. It is recommended that cut outs for electrical boxes and other protrusions be done in the field by a qualified contractor.

Prior to purchasing this product, please be prepared to provide the following information, if requested:

  • Pictures of the space
  • Wall elevation drawings with dimensions for width and height
  • Basic floor plan with dimensions

    We had them installed in our Testing Center to minimize hallway traffic noise and so far, so good.

  2. Verified Customer

    Used to provide barrier on wall shared with server room and absorb interior room noise for audio recording.

  3. Verified Customer

    Sound panels.
    Install was accurate.

  4. Verified Customer

    I used the product for sound isolation but I think it would be useful for insulating interior walls, and as a way to cover damaged or unsightly wallboard.
