PROCELL® Composite products offer the best possible acoustic result due to its multi-layer construction. It's mostly used for marine applications.4 layers:

THE PROTECTIVE FACING

Each with important functions acts as a heat reflective/resistant surface; provides easy clean surface that is oil and dirt resistant; protects against dust, grease and moisture.

THE ABSORPTION LAYER (ABSORBER)

A thick layer of fire zero rated PROCELL® foam which soaks up noise and stops it bouncing around the source of noise.

THE TRANSMISSION LAYER

A high-density barrier provides the highest possible mass and gives the best noise reduction. 2 mm thickness, 3,5 kg per square meter bitumen 0,5 mm thickness, 6,5 kg per square meter lead sheet

THE ISOLATION LAYER (DECOUPLER)

This thin layer of foam has a crucial function: it acts like the gap in double glazing and stops the noise which hits the transmission layer being carried through to the bulkhead and absorbs the vibration of the transmission layer
