Industrial noise control barriers are loaded vinyl barriers that combine mass, flexibility, and limpness to block noise from transmitting from one area to another. They are available clear, non-reinforced, and reinforced in a variety of weights and styles to meet a multitude of applications.
Non-reinforced vinyl noise barriers are most commonly used to reduce sound transmission between wall and ceiling partitions. They work by adding additional mass as well as diaphragmatic absorption thus increasing the Sound Transmission Class (STC) of the partition. Non-reinforced vinyl noise barriers are also used as the blocking component in barrier septum composites, pipe and duct lagging, and short-term barrier walls.
Reinforced vinyl noise barriers are typically used in applications requiring high tensile, breaking, and tear strength, as well as excellent UV and weather resistance such as in long term exterior sound walls. Reinforced vinyl noise barrier is also used as the blocking component in barrier backed composites. When used in conjunction with a quilted fiberglass absorber, STC ratings of up to 32 can be achieved.
Specialty vinyl noise barriers include a marine barrier which is a 1PSF barrier material with a woven fiberglass cloth facing. Marine barrier offers superior fire ratings when installed against bulkheads, etc. Where radiation or RF resistance is required in addition to noise reduction, a 1PSF lead sheet is used as a septum with a fiberglass absorber/decoupler on both sides.
