The VETUS Prometech Single Sound Insulation Sheet is a high-performance acoustic polyurethane foam specially treated to offer flame retardancy to BS:476, parts 6 and 7, Class “0” - the highest rating on the market today! Combined with a single damping layer, each sheet provides good sound reduction and the highest level of safety.
Glass cloth facing
Flexible glass cloth facing, for extreme strength, durability and a high tech appearance to your engine room. Class 0 heat and fire resistant. Fully liquid tight.
Single Damping Layer
The damping layer used in VETUS sound insulation is designed to prevent heavy, low frequency vibrations from reaching the engine room walls or the hull of the boat. With a single damping layer, huge sound reductions are already achieved. The damping layer is made of vinyl, loaded with naturally occurring minerals. This material is free of lead, unrefined aromatic oils and bitumen.

VETUS Sound Insulation Beginner's Guide:
Preparing the engine room
Sound is like water and until the last gap is closed, it will find a way out of the engine room. Therefore it's important to cover as much of the surface in the engine room as possible and to close all possible leaks. Any small gaps or holes in, between or under the bulkheads should be filled with flexible sealant, foam or other material. When the ‘engine room’ is in direct contact with the bilge or other spaces that run through the boat, it is recommended to build bulkheads or a box around the engine.
Fitting the sheets While fitting the sheets, work around obstacles by cutting the sheet into the right shape and try to fit the puzzle as neatly as possible before actually sticking the sheets in place. Note that tanks tend to amplify noise. When a tank is in the same space as the engine, cover the tank in insulation sheets or build a bulkhead between them.
Hatches and air intakes
Hatches and air intakes may leak noise. Hatches can be soundproofed by using insulation tape between the touching surfaces. Air intakes however are more difficult to insulate, as the engine needs air for combustion and cooling. Creating a labyrinth or installing a special damper will generally solve the noise leak without choking the engine.
