Acoustic Blankets ANC-AB13 (1lb 3”) Noise Barrier/Sound Absorber Composite

Sound Barrier Walls

The barrier septum configuration offers the benefits of sound absorber and noise barriers. A non-reinforced 1-lb psf loaded vinyl barrier is sandwiched between 1” and a 2” layer of quilted fiberglass absorbers. The sound absorber is also effective at absorbing low frequencies, making it ideal for reducing bass noise. Curtain panels are constructed with grommets across the top and hook and loop fasteners along the vertical edges. Rolls are available 4’ wide up to 25’ long and can be either bound or unbound.
