Air Shaft Insulation for Ships to Reduce Engine Noise

Air shaft insulation with Merfocell PU sound absorber

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 area. 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 sound absorber. We have various noise absorbing products to insulate the air shaft (or air ducts). We recommend using a product that has 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:
