The ROCKWOOL Technical Insulation products are based on stone wool, which cannot burn and which can stand temperatures up to 1000 degrees C without melting. Thus ROCKWOOL stone wool provides the best guarantee for an effective fire protection on board ships and offshore platforms.

ROCKWOOL stone wool fibres can withstand more than 1000°C without melting, whereas the binding agent is lost at temperatures in excess of 250°C. When the temperature rises above 250°C, the binder will evaporate in the zone which is exposed to 250°C or more. But the fibres will remain intact as their inbuilt cohesiveness and layering will keep the fibres together, ensuring that the material will retain its rigidity and protect the material beneath it from being affected by the fire.

Since mineral fibres are highly resistant to temperature variations, ROCKWOOL mineral wool can be used under conditions of very high temperature, provided that it is installed in such a way that mechanical stress will not alter its shape when the binder evaporates.

When pipes, ducts or other go through a bulkhead or deck it is called a penetration. There are special rules regarding insulation when the decks or bulkheads with fire class are penetrated.

The pipe going through a fire classed structure must be made of steel and must have a length of minimum 900mm. IMO suggest to use 450mm on each side of the construction.

The min. 900mm insulation must have the same insulation class weight as the structure that is penetrated.

Floating Floor

A Floating Floor is as the name tells a floor that does not need to be nailed or glued to the sub floor. The term floating floor refers to the way the installation is done.

These floors can secure a better comfort because of the sound reduction it gives between the individual decks. To prevent noise –from travelling from one cabin to another you must use an insulation solution which has the necessary rigidity, elasticity and noise reduction/absorption.

Draught Stop

The draught stops must be placed above ceilings and behind panels to divide the spaces into smaller compartments. They must not be placed more then 14 meters apart.

The draught stopper should be made of a product with wire mesh on one side and armed alu foil on the other side.
