Insulate deck

What is the problem?
A light deck (but also light hatches) above the engine often leaks engine noise, which means that sitting outside is often not really comfortable. The nuisance is experienced as tiring, especially on longer trips. The low-frequency sound of the engine is then mainly the source of annoyance.

What is the solution?
The best solution is to make the deck floating and to insulate it using mass (add weight).

Making the deck floatingn
For see the rafters of strips Regufoam or the alternative Agglomer. Regufoam and Agglomer Strips are resilient products that provide a break between hull and the deck (or floor). A floating deck reduces contact noise, pay attention to the edges that they do not allow water to pass through, seal well if it is an outside deck). In a finished ship it is usually not possible to make the deck floating, insulating with mass is an excellent alternative!

Insulating the floor with mass
The floor is insulated by providing it with Isomat KE or Isomat TS, adding mass ensures better sound insulation, the heavier the floor becomes, the higher the insulation value. The Isomat can be finished with, for example, plywood (the best result is achieved by gluing everything together). This is where the finishing floor comes in, such as carpeting. Both Isomat types can also be fitted directly with a floor covering, but a sandwich construction gives the best result.

Instead of Isomat you can also use Merfoplex plates as a floor, placed on Agglomer or Regufoam Strips for decoupling. Then you don't need Isomat or plywood!
