Acousti- Barriers, composites and Lagging

IES IBSC Composite features a non-reinforced loaded vinyl noise barrier septum (middle) with a quilted fiberglass sound absorber on both sides. Ideally suited as an acoustical liner, the inner layer of quilted fiberglass decouples the barrier from the surface to improve its noise blocking ability while the outer layer adds sound absorption to the treated environment.

IES IBBC composite features a reinforced loaded vinyl noise barrier with a quilted fiberglass sound absorber on one side. The rugged durable exterior barrier is commonly used as a wrap or acoustical jacket due to its ability to conform to any shape. The quilted fiberglass layer decouples the noise barrier to enhance its acoustical performance. Both styles are available in curtain panels, bound or unbound rolls, custom fabrications or die-cut pieces, in standard vinyl-coated-fiberglass-cloth facings, high-temp silicone facings or economy facings.

Over 800 sound absorption/barrier panels in 50 different sizes line the interior of Tennessee Gas Pipeline's compressor station 254.

The composite, made up of quilted fiberglass and a 1 lb./sq.ft. barrier, would does double duty for Tennessee Gas by absorbing airborne sound waves and increasing the transmission loss ability of the building. Leaks at the seams of the panels are prevented by using a velcro attached noise barrier batten.

Post-installation testing showed the solution performed better than the promised results. The noise level at the property line was reduced from 60dB(A) to 45dB(A). 5dB(A) lower than what was specified. And while noise levels within the building were not as critical, Tennessee Gas officials were pleased the employees could now hold a conversation without shouting.

In addition, Tennessee Gas found that the light colored fabric facing dramatically improved the lighting inside the building.

IB-10 NR is a flexible non-reinforced loaded vinyl barrier that is designed to stop the passage of sound through walls, ceilings, and floors.

Typical uses include as a noise barrier in dry wall and stud construction to substantially improve transmission loss between rooms. Also, utilized as a barrier septum material in acoustical curtain and foam composites.
