Product Description

The AlphaSorb® Barrier Fabric Wrapped Wall Panels offer the sound absorption value of standard wall panels combined with the soundproofing capabilities of mass loaded vinyl. 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 cutouts 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
  • Drawings indicating dimensions for obstacles, trim, or protrusions that would affect panel dimensions
  • Drawings indicating the width, height, and placement of any doors, windows, and electrical boxes


  • Block & absorb sound with one product
  • A perfect retro-fit solution
  • Reduce reverberation and echo
  • Improves speech intelligibility
