INC Sorba-Glas® Quilted Noise Absorber
INC Sorba-Glas noise absorbers reduce overall noise levels by dissipating noise energy. Sorba-Glas products combine excellent acoustical performance with a superior ASTM-E84 Class I fire-rating and a tough, impervious facing making it the ideal sound absorber for a wide variety of applications.
Sorba-Glas
is offered in bulk rolls, fabricated
Wall Blankets, and in custom fabricated
shapes. It is also a featured component in Sorba-Glas Composite
Materials, the INC Flexi-Sorb® Noise Control
Curtain System and on the
INC Portable Noise
Screen. Sorba-Glas is available with one or
both sides faced, in 1" and 2" thicknesses, limited range
of colors and with an optional "hi-temp" silicone coating.

- Light weight, tough, highly abrasion resistant quilted facing is impervious to water, dust, oils grease, airborne contaminants, and most solvents
- ASTM-E84 Class I fire rating
- Standard color is Gray, special orders available in White, Blue or Tan
- 250°F maximum temperature range for standard product
- Hi-Temp silicone facings available for 500°F maximum temperature range
- Polyester scrim on un-faced side provides product stability and encapsulates any loose fibers
- Easily cut, sewn, stapled or grommeted
- Easily attached to many surfaces using grommeted holes, glued directly to surface, using INC mounting-pin assemblies, or common mechanical fasteners (see also: INC Adhesives and Accessories)

Applications
Sorba-Glas is the best choice for any situation where a noise absorber with an extremely tough facing is required, and in applications where ASTM-E84 Class I fire performance is desired.
The Sorba-Glas Wall Blanket is a popular application of the product used to reduce reverberant noise in spaces where hard surfaces are predominant. This reliable treatment is effective in a wide variety of in-plant manufacturing and warehouse situations, as well as in many commercial and institutional situations such as multi-purpose rooms, gymnasiums, swimming pool areas, and workout rooms.

Custom Shapes & Fabricated Parts
Another great Sorba-Glas application is lining the hard surfaced interior of an enclosure, cabinet, OEM housing or equipment guarding to enhance overall acoustical performance. This is a very effective way of adding several decibels of additional noise reduction.
These custom fabricated Sorba-Glas pieces are typical of those used to line machine cabinets, housings, guards, etc. The impervious quilted facing prevents oil and other contaminants from penetrating the blanket's inner fibers.
Product Selection Tips
- Select "Faced One Side" when the material will be attached to a wall or other surface
- Select "Faced Both Sides" when the material will be free-hanging or otherwise exposed on both sides or for additional durability where product may be removed or handled periodically
- Select 1" thickness for most broad band noise problems
- Select the 2" thickness where noise levels are higher in the lower frequencies bands - below 500 Hz or when overall noise levels in general are extremely high
