Insulate floor, deck and hatch

Insulation for a boats and yachts: deck, floor and hatch
The lack of mass is the main reason why a deck, floor or hatch on a boat or yacht cannot isolate engine noise enough, with an uncomfortable craft as a result. On this page we describe the insulation and isolation of engine noise by insulating the wheelhouse floor, deck, hatch and covers.

How to insulate the floor in the wheelhouse or cabin?
When building a vessel, ideally the floor in the wheelhouse or cabin is decoupled from the frame (hull) with vibration insulating products such as Polypress Strips for example. This reduces vibrations in the floor originating from the engine, machine or propellers. If the ship is already been build you can insulate the floor by adding mass to the floor.

The best way to go about is by applying Isomat KE. Insulating Isomat is in a sense adding weight to a light weight structure of a vessel. The more weight or mass you add, the better the insulation and the better the result. We recommend an Isomat with a weight of 14 kg/m² to be glued with Contact Adhesive. You can choose between the Isomat KE and TS. The latter is mostly used in luxurious yachts because of the composition. Afterwards you need to cover the Isomat with carpeting e.g.

How to insulate an engine hatch or cover
Hatch or engine covers are in most cases equal to the surrounding deck or floor and cannot made any thicker, therefore only the inside can be insulated. This can also be done with Isomat KE or TS. By adding mass to a hatch or cover the insulation will improve. If the engine is directly underneath the hatch or cover the finishing touch would be absorbing product on top of the Isomat. This will increase the insulation ever further. You can also use Merfocom to insulate the hatch or cover. This product is a combination of soundproofing and noise insulation.

How to make the wheelhouse more quiet
To improve the acoustic climate in the wheelhouse of your vessel you can mount Akotherm SF or Acousticcell VSP to the ceiling, as a headliner. This product reduces the sound pressure in the cabin or wheelhouse by absorbing engine noise.
