Insulation Sorberbarrier AGC25/4.5 6.8kg/m2 25mm 1.3 x 1m for engine rooms, bulkheads & deck heads

Sorberbarrier® AGC is a barrier-absorber composite noise control product that offers both excellent noise transmission loss and high sound absorption. It was specially developed to provide complete noise control solutions within one high performance, versatile product. Its unique construction comprises a high mass, flexible noise barrier, Wavebar®, laminated between two layers of flexible acoustic foam, Sorberfoam™, consisting of a sound absorption layer and a decoupling layer. A durable, flame retardant, aluminium foil glass cloth facing - AGC, is laminated to the outer absorptive foam layer. Sorberfoam™ is Pyrotek’s specially developed combustion modified, polyurethane foam offering high sound absorption across a broad frequency range and engineered to resist degradation or foam rot. The faced foam layer absorbs airborne sound and reduces the effect of reverberant sound build-up within an enclosed space. Its AGC facing alters the natural absorption curve enhancing its sound absorption in mid to low frequencies besides providing additional protection to the foam from mechanical stress and dirt, oil and liquid ingress. Being flame retardant, it further enhances the fire and thermal insulation performance of the foam. The decoupling layer isolates the mass barrier layer from the structure to which it is bonded. This allows the decoupled mass barrier to remain flexible at all times, significantly enhancing its transmission loss performance. Sorberbarrier AGC is easy to install without the need for specialist tools or equipment.
