The AlphaSorb® Dual-Sided Absorptive Sound Blanket (formerly the AQFA-10 Absorber Sound Blanket) is used to add sound absorption to interior applications to reduce reverberation and echo. They are are constructed using two layers of 1 in. thick acoustical fiberglass batting and feature a durable vinyl-coated fiberglass cloth facing.

These blankets are available in a variety of colors and stitch patterns, and can be made in any size up to 4' x 25.' AlphaSorb® Dual-Sided Absorptive Sound Blankets are ideal for large reflective industrial environments or equipment rooms in buildings where reverberant noise energy needs to be reduced. They may also be used to improve sound transmission loss when used in enclosures or to supplement plywood structures on job sites to reduce reflected noise for workers.

Typical uses include industrial plants, gymnasiums, auditoriums, and warehouses. These sound-absorption blankets are Class 1 fire-rated and have a sound absorption rating of 0.85.

Standard 4' x 8' blanket panels may be ordered online. Other sizes up to 4 ft. x 25 ft. are available, please contact us with your specific requirements.
