Air Shaft of a Barge

What's the problem?  
The air shaft of the engine room is often opened during sailing to dissipate heat. The shaft is actually a large sound leakage, which gives engine noise a free passage to the surrounding environment. This creates noise nuisance on the deck and for the surroundings, for instance during a lock passage.

What is the solution?
To keep the engine noise in the engine room, the entire shaft must be completely covered with an absorption material. There are various absorption materials with which you can cover the air shaft of the inland vessel. We recommend using an absorption material that contains a PU top layer. This top layer protects the absorption foam against oil, moisture and dirt.

Which products to use where?
For barges and commercial vessels (CE)

  • Merfocell PU: A self-adhesive absorption material with a PU top layer. Flexible polyurethane foam, for both flat and curved surfaces.
  • Flamex PUA self-adhesive absorption material with a PU top layer. Rigid melamine foam, to be applied on a flat surface.
