Air shaft insulation for ships

Air shaft insulation for cargo ships and vessels
The air shaft of the engine room in a commercial vessel, such as a cargo ship, are is often opened during sailing to dissipate heat. Since the air shaft is an open connection to the outside world it usually one of the most common a noise problems in marine and shipping. Not only for personnel on board but also for the surrounding environment. The solution to this problem, insulating mainly engine noise from the engine room, is quite simple.

How to insulate an air shaft
To keep the engine noise in the engine room, the entire shaft must be completely covered with an acoustic noise absorbent product. We have various noise absorbing products to insulate the air shaft (or air ducts). We recommend using an absorption product that contains a protective PU top layer, this prevents the intrusion of dirt, oil and moisture. And maybe a product with an CE certificate or heat resistance.
These are the products we recommend:
