ROCWOOL A/S has for many years been one of the leading supplies of fire insulation for the international marine and offshore sector.

ROCKWOOL A/S offers a wide range of specially developed products and constructions which have been tested and approved according to the latest standards and by all major clasiffication societies.

There are stringent requirements of insulation materials to be used in the marine and offshore sector. For the sake of both safety and funcionality it is of párticulary great importance that the products have good properties in respect of fire insulation, water repellence and sound reduction.

ROCKWOOL marine and offshore insulation is made of stone wool, which possesses superior properties in these very fields.

ROCKWOOL A/S markets a wide range of solutions for different types od H & A contructions. This applies to constructions of both aluminium and steel - and whether they have to be insulated against fire on one side or both sides.

Constructions and products have been developed so that they will both meet the stringent fire requeriments and comply with the costumers' needs and wishes for thickness, weight and ease of installation.

Pipe insulation is rarely visible, but often decisive for the confort on board. At the same time pipe insulation is neccesary to reduce the suirface temperature on the pipes so that people working in the engine room are not injured by contact with the hot pipes.

To prevent corrosion and blokage of pipes in product tankers it can further more be decisive to avoid too great a heat loss from the pipe.

ROCKWOOL A/S has a wide choice of solutions for pipe insulation, which satisfy all these requirements, for a large pipes as well as for small pipes. One example is Marine Universal Pipe Section a flexible Pipe Section - which ensures a quick and effective installation without cutting, also round elbows.

Tanks to be insulated comprise both small tanks and large tanks such as gas tanks

Tanks often require insulation in two layers to prevent any gaps in the insulation, which can result in heat loss or cooling of the tank

ROCKWOOL products ensure tight joints as the products can easily be butted.

As in the case of fire constrcutionsit also applies to insulation of pipes ans tanks that the material must be non-combustoble according to IMO A799(19)

To obtain a good comfort a good sound absorption is required between yhe individual decks. To prevent noise - particulary impact sound - from traveling from one room to another you must use an insulation solution that has the necesary rigidity, elasticity, and sound absorption. For this purpose ROCKWOOL A/S has developed and for many years marketed Marine Slab 140.

To be used together with Marine Slab 140 a number of companies have developed a load spreading board.

This provides a soundproof construction. which allows for the use of different materials.

These solutions are extensively used on cruise liners where stringent requeriments are made in order that people can stay and enjoy their cruise without being bothered by noise.

For the sake of the fire safety owners and producers of ship's panels and living quarters often require the core of the panels to consist of stine wool.

For that pupose ROCKWOOL A/S has together with costumers developed a great many special products possesing high compressive strength as well as great fire resistance, and which have been approved as non-combustible according to IMO's latest regulation.

If you as a producer of panels and ceilings choose Rockwool marine product, you are given a good start towards obtaining an ooptimal en result.

ROCKWOOL A/S supplies partly raw materials for cutting in to lamellas, pártly ready-cut lamellas, which can be glued direct to the panel.

The stone wool used can be of different types, depending on the requirements as to fire safety, comnpression stability etc

There are many reasons for choosing insulation products with facings. It is generally done tio obtain a vapour barrier, which prevents formation of condensation of the cold side of a construction. ROCKWOOL A/S con for this purpose offer a number of products faced with a reinforced alu foil, which ensures a strong surface.

In addition to this, ROCKWOOL A/S can offer products with a glass fabric, which often provides a cheaper and lighter construction. These products are typically used for a car decks, air-conditioning plants, engine rooms, lift shafts or the like.

Rockwool A/S has developed a special range of marine products, which meet the requeriments of IMO's regulation at any time. For all constructions there is consequently a Rockwool solution that has the required approval
