BSC-24 Noise Barrier/Sound Absorber Composite

BSC-24The barrier septum configuration offers the benefits of both sound absorption and noise barrier in one product. A non-reinforced 1-lb psf loaded vinyl barrier is sandwiched between two layers of 1” thick quilted fiberglass sound absorbers. When tested to ATSM E84, the composite has a Class 1 or A flammability rating, and is commonly used in plenums.

  • Rolls are available 4’ wide up to 25’ long
  • Available die-cut to 2’ x 4’ to lay on top of standard ceiling tiles
  • Hi-temp, economy Scrim facing on both sides


Typical uses include lining stud cavity of staggered stud drywall wall construction, or laid on top of ceiling tiles to improve transmission loss. Also may be suspended from roof deck to drywall to close gaps between rooms to prevent noise flanking over the top of the partition wall. Also used over existing walls in mechanical rooms or similar.
