Pyrotek Sorberbarrier Diesel Engine Sound Insulation (Double) 32Mm 8Kg/M2 (1Mx1.3M)

Best in Class product

8kg/m2 (250kg/m3), 32mm thick SorberBarrier Aluminium Faced Sound Insulation Sheet for diesel engines!

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 reverberant 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. This grade especially recommended for Diesel Engines.

Features:

• 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
• Superior noise reduction per given thickness of product
• Long service life

Specifications:

• Product Name: SorberBarrier Double
• Surface Finish: Plain foam, polyurethane film, aluminised polyester, foil, perforated vinyl, reinforced aluminium foil
• Barrier Weight: 8.0 kg/m² 
• Product Size: 1.30 x 1.0 m
• Foam Thickness: 32 mm (polyether hydrolysis resistant)
• Flammability (AS 1530.3, 1989): Ignitability Index = 0 (Highest Rating)
• Spread of flame index = 0
• Heat evolved index = 0
• Smoke developed index = 0-1

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. Unique manufacturing technique ensures total fusion of the foam to the barrier (no separation possible - a big issue on aged or damaged product)

SorberBarrier is a composite product comprised of two layers of acoustic foam (Sound SorberTM) 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.

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 especially in overhead applications. These products can easily be cut with a sharp knife and can be die cut into any complex shape.
