  • Sorba-Glas® Wall Blankets

    Tough, High Performance, Flexible Noise Absorbing Blankets

    Industrial Noise Control, Inc. Sorba-Glas® Wall Blankets provide excellent noise absorption characteristics, durability and an ASTM-E84 Class I Fire Rating.  This product features an attractive, abrasion resistant quilted facing that is impervious to dirt, grease, solvents and airborne contaminants.

    Poor acoustical conditions in interior spaces can create an uncomfortable sea of noise which often leads to fatigue, inability to concentrate, poor speech intelligibility, miscommunication, stress related ailments and hearing damage. 

    Installing Sorba-Glas® Wall Blankets will dramatically reduce reverberation and noise levels without any interruption in production routines, housekeeping activities and work flow.  Hanging Sorba-Glas® Wall Blankets on walls, ceilings, partitions or equipment housings is an easy way to create a safer and more productive workspace. 

    The excellent sound absorption properties of Sorba-Glas® products make solving many reverberation problems economical by requiring as little as 25-30% coverage of the reflective surfaces to be effective. INC Sorba-Glas® Wall Blankets can be mounted anywhere on any surface and are easily field cut & trimmed to accommodate obstructions and interferences.
