4.5kg/m2 (140kg/m3) 32mm thick barrier SorberBarrier Aluminium Faced Sound Insulation Sheet 4.5kg/m2, 32mm thick barrier for petrol engines.

1m x 1.3m

Overview:
Noise control can be a complicated business, sometimes it requires a transmission loss barrier and at other times, an absorber to soften the noise and control any reverberent noise build up, and there are times when the problem requires both of these approaches to achieve the best result.

This is where Pyrotek's range of composite barrier/absorber materials come to the fore as they are designed to deal with these situations in the most effective and economical way. Applications such as compressor, generator or plant rooms, mobile machinery cabins and marine craft engine rooms all need this treatment to ensure the well being of those in the enclosed area, as well as those outside of it.

Construction and performance:
The decoupled high mass barrier layer ensures maximum reduction in the transmission of the sound wave through the structure to which it is attached, while the hydrolysis-resistant acoustic foam material reduces the noise effect and any reverberant noise build-up within the enclosed space by absorbing the airborne sound waves.

SorberBarrier is a composite product comprised of two layers of acoustic foam (SoundsorberTM) and a single flexible barrier.

This composite is designed to provide maximum noise reduction in the hardest environment. SorberBarrier is a composite material, comprising of a 6mm Decoupling layer with Barium loaded vinyl and acoustic top layer of foam. The materials applications include Engine rooms for the marine market, generator,compressor enclosures, plant rooms. Applications where the use of an effective absorber and transmission barrier are required.

Benefits:
Hydrolysis resistant foam outlasts conventional acoustic foam threefold.
Highly flexible barrier layer equals high transmission loss.
Flame-resistant surface layer, recommended for marine use.
Unique manufacturing technique ensures total fusion of the foam to the barrier.
Excellent noise reduction per given thickness of product.

Installation:
These composites can be adhered to the substrate with factory-supplied pressure-sensitive adhesives for temperatures up to 75°C. It is recommended that sprayable contact adhesive "Sorberbond" (requires spray equipment), Ados Ultra High Strength High Heat aerosol or mechanical fasteners (hanger pins) be used for these heavy loaded composites in overhead applications. These products can easily be cut with a sharp knife and can be die cut into any complex shape.
