Quilted Noise Absorbers and Mass-Loaded Flexible Barriers Combined
INC noise control composite materials achieve superior acoustical performance by combining two basic noise reduction strategies in a single product. An INC mass-loaded flexible noise barrier is permanently laminated to one of our Sorba-Glas absorbers to create a material that both blocks and absorbs noise.
Naturally, all the great features of our Sorba-Glas quilted noise absorber are also found in the composite material – excellent acoustical performance, a tough facing that is impervious to water, oils, dust, dirt and airborne contaminants and meets ASTM E84 Class I fire rating.
Any of the INC Flexible Noise Barrier materials can be used with any absorber to meet most application requirements.
Sorba-Glas Product Features
- Absorber component has a tough, highly abrasion resistant quilted facing impervious to water, dust, oils grease, airborne contaminants, and most solvents
- Absorber component meets ASTM E84 Class I fire rating
- Sorba-Glas quilted noise absorber is permanently laminated to the barrier component
- Mass-Loaded vinyl barriers are available in a variety of weights, and in polyester-reinforced and non-reinforced versions
Sorba-Glas Material Applications
A Sorba-Glas noise control composite is the best choice for any situation where a flexible material that both blocks and absorbs noise is desired, where an extremely tough facing on the absorber component is required, or in applications where an ASTM-E84 Class I fire rating is desired.
Sorba-Glas composites are used for a wide variety of situations - most commonly to create track-mounted or wall mounted noise curtain walls, and to add acoustical properties to any sort of structure such as an existing equipment room, an OEM machine cabinet or guard.
Sorba-Glas "septum" curtain panels (noise barrier sandwiched between two layers of Sorba-Glas) are an excellent choice for creating acoustical partitions above suspended ceilings effectively extending hard partitions above suspended ceilings to greatly reduce cross talk.
Sorba-Glas Product Selection Tips
- Select poly-reinforced (P) vinyl barriers in situations where the vinyl will be physically stressed in any way- for example when hanging panels vertically from hooks, or in situations where the vinyl will undergo repetitive contact.
- Select non-reinforced (N) vinyl barriers when the vinyl will not be physically stressed, such as to line an equipment cabinet or wrapping ducts or pipes.
- Select lighter density barriers for general use, where lighter overall weight is desired, or for open-top enclosures or partial barriers.
- Select heavier density barriers for greater noise level reduction.
