Insulating Floor, Deck and Hatch

What is the problem? 


Dek- en vloerisolatieA light floor, deck or hatch above the engine often leaks engine noise, making sitting outside uncomfortable. The nuisance can be tiresome, especially on longer trips. The nuisance in the wheelhouse is not only caused by a poorly insulated floor, but also by the fact that noise cannot exit, in contrast to noise that occurs outside. Subsequently, the “locked up sound” creates a hum and is perceived as pressure on the ears, especially with smaller wheelhouses.

What is the solution?
The best solution is to set up a floating floor and deck (uncoupling them from the hull) and insulation by adding mass. Adding mass is also the best solution for insulating shutters.  

Creating a floating floor and deck
Provide the rafters with Regufoam or the alternative Agglomer strips. The floor or deck will be placed on these vibration-isolating strips. Agglomer strips are resilient products that provide seperation between the hull and the deck or floor. A floating floor effectively reduces impact noise.

In case of a finished ship, usually a floor that floats on the bulkheads cannot be created, because the ship is boarded-up on the inside. In this case, you can insulate the floor by adding Isomat to the existing floor. Decoupling can be achieved by applying Agglomer with a thickness of 10 mm upon the Isomat with a supporting plate such as plywood on top of it. After this, the floor covering is placed upon this plate. Make sure that this floor never touches the hull!

Insulating the floor with mass
A floor or deck is insulated by equipping it with Isomat KE or Isomat TS, adding mass ensures better insulation: the heavier the floor, the higher the insulation value. Isomat can be finished with plywood for example (the best result is achieved by gluing everything together). One of the options to finish the floor is by using a carpet. Both Isomat types, Isomat KE and TS, can also directly be equipped with a floor covering, but a sandwich construction gives the optimal better result.

Tip
Equip the ceiling of the wheelhouse with absorption material of at least 25 mm thick. This reduces the sound pressure in the room. Acusticell VSP or Akotherm SF are the right choice here. On the Yachts and Boat page you will find more information about insulating your vessel.
