Comfort on board plays an ever increasing role. To reduce engine noise when you are cruising is part of that development where an effective reduction of the noise level can only be achieved by using top-quality material and careful manufacturing. A decrease of the noise level by 3-4 dBA represents half of the acoustic noise.

The insulating material (1) offered by Volkswagen Marine has a multilayer structure designed to dampen different frequencies and vibrations.

The first layer consisting of fine fleece aims to avoid the transmission of vibrations to the wall of the engine compartment whereas the second layer, a heavy foil with a thickness of 2 mm and a weight of 3.7 kg/m², effectively reduces acoustic noise in the lower frequencies. The volume fleece forming the next layer provides the thermal and acoustic insulation of the hull. The surface of the material is made of resistant, aluminium coated glass fibre where existing sound waves are reflected and diffused by the honeycomb structure.

The material is flame resistant, oil and fuel resistant and approved to EN ISO 9094-1, 9094-2 and 4589-3. It is available as self-adhesive panels measuring 1040 x 1100 mm. An adhesive

tape to close and seal the abutting edges can be obtained. For the ventilation of the engine compartment, dampened pipes are available in different diameters.
