Marine and offshoreinsulation worldwide
For many years ROCKWOOL Marine & Offshore has been one of theleading suppliers marine and offshore insulation worldwide. ROCKWOOL
Marine & offshore is part of the ROCKWOOL group, which is the world
largest manufacturer of stone wool.
ROCKWOOL markets a wide range of specially developed products and
constructions which have been tested and approved according to the latest
standards and by all major classification societies, just as ROCKWOOL is
certified according to the latest MED directive. As Notified Body ROCKWOOL
has chosen Det Norske Veritas, which consequently guarantees our quality.
There are stringent requirements of insulation materials to be used in the
marine & offshore sector. For the sake of both safety and functionality it is
of particularly great importance that the products have good properties
in respect of fire insulation, water repellence and sound reduction.
ROCKWOOL Marine & Offshore insulation is made of stone wool,
which possesses superior properties in these very fields.

Advantages
One layersolution
The construction is based on a solution wherethe construction is made with one product inone layer. This leads to a faster installat ion.
Low construction
weight
The construction is based on products with alow density and/or low thickness which leadsto a low total construction weight.
Fastinstallation
The construction is based on Mats which re-duces the cutting especially around stiffeners,and consequently faster installat ion time.
Safesolution
The constructions are based on a multiple,typical two layer solution which results in moresafe solution especially due to staggered joints.
Optimal soundproperties
The construction is based on products with higherdensity and/or more thickness which results inbetter sound properties
Easyhandling
The constructions are based on Batts, where thesmall size and fixed structure of the products givean easy handling in respect to cutting and installation.

Comfort Insulation
The requirements of the indoor climate and comfort have becomemore stringent during the recent years. The insulation constitutes an
important factor of this, as it ensures obtaining the correct temperature
as comfort insulation.
The great advantage of the Rockwool products is that the high level of thermal
insulation can be combined with excellent noise reduction capabilities and often
also fire protection constructions will act as thermal comfort insulation.
All ROCKWOOL Marine & Offshore products will fulfil the IMO rules of non-
combustibility and low flame spread and besides this the products have
excellent water repellent properties which are also important as comfort insu-
lation often is placed directly up against the outer construction with changing
temperatures.
Floating Floors
To obtain a good comfort a good noise reduction is required between the indivi-
dual decks. To prevent noise particularly impact sound and structure borne noise
from travelling from one cabin to another you must use an insulation solution
which has the necessary rigidity, elasticity and noise reduction/absorption. For
this purpose ROCKWOOL Marine & Offshore has developed and for many years
marketed the Rockwool Marine Slab 140 with an excellent track record. This
product is widely used by dedicated floating floor companies as the core mate-
rial, combined with different types of load spreading top layers and base layers.
These solutions are extensively used
on cruise liners where stringent require-
ments are made in order for people to
be able to enjoy their cruise without
being bothered by noise.
At the same time many of these floating
floor constructions are made as approved
A-60 Deck Fire Protection Solutions.
ROCKWOOL Marine & Offshore also
supplies solutions for floating floor,
approved for A-60 Deck Fire Protection,
see page 5.

Panels
Throughout the accommodation
areas of a vessel or living quarter, it is
required to have B-Class fire restriction
zones and fire protection between each
cabin. And at the same time it is needed to
have comfort and noise insulation between each
cabin, towards public areas etc.
For this purpose the Rockwool Marine Slab range of products has proven to
be highly successful.
ROCKWOOL Marine & Offshore has together with the customers developed
a great number of special products possessing high compressive and
delaminating strength as well as great fire resistance, which has been
approved as non-combustible according to latest IMO regulations.
The panel and door manufacturers here-by have an outstanding core material
for the fabrication of sandwich constructions.
Sound Solutions
Today an increasing focus on noise reduction is present, which extents farbeyond the rules of national marine authorities and IMO, such as res A.468(XII).
The technical aspects in this area are quite complex and often requires spe-
cialist companies to perform sound design work, calculations and final onboard
measurements.
Rockwool products have excellent properties as; sound absorbers, stopping
structural borne noise (i.e. with floating floor and bulkhead constructions)
and as noise reduction by panels.
ROCKWOOL Marine & Offshore is assisting in the battle against noise.
A large range of basic product measurements has been performed, to create
the necessary data for the further calculations.
A series of typical constructions have also been tested for the noise reduction
capabilities.
Please see our web site

for dedicated specialist
information and
measuring results.

Aquaduct CLare special pat-
ented Rockwool products where
the vertical direction of the fibres
provides an excellent compres-
sion resistance at low thicknesses
(down to 10 mm thickness). Thefibres are bonded to a reinforced aluminium foil outer facing
and the product can be supplied with very low tolerances.
In most cases Aquaduct CL will be the optimal choice for
Pipe in Pipe solutions.
Aquaduct Sectionsare rigid
pre-formed circular units of
Rockwool insulation supplied
with or without an outer covering.
Aquaduct sections are available
in almost any combination of dia-meter, thickness and length and can be adapted to
individual needs and specifications. Aquaduct Sections
are the optimal choice for bigger sizes of pipe.
Aquaduct PSMis
a rigid Rockwool
slab having a glass
scrim or reinforced
aluminium foil facing
bonded to one side
and triangular grooves in the other.
The grooves allow the slab to wrap
around and closely fit specified large
diametres.
Aquaduct Bevelled
Lagsare trapezoidal
strips of Rockwool
rigid slab designed
to contour specified
large diametres. The
lags can be supplied
loose or bonded to a reinforced
foil or metal outer sheet. The use of
Aquaduct Bevelled Lags offers the
designer the facility to incorporate
inset strips of varying thicknesses.
Aquaduct Loose Fill
is a specially graded,
granular insulation
designed to in-fill
around pipe bundles
and to fully fill irregu-
lar voids. Aquaduct
Loose Fill can be installed at a wide
range of densities, either by hand
packing or by use of specially de-
signed blowing equipment.
Aquaduct - Thermal Insulationsolutions for Sub-Sea Pipeline
ROCKWOOLs unique product properties within fire resistance, water and mois-ture repellent, sound reduction and thermal conductivity, which traditionally have
been used e.g. within the marine and offshore sector, can now with benefit be
used for thermal insulation of Sub-Sea Pipelines.
The increased efficiency improvement
when drilling for oil and use of the worlds oil
reserves mean that we operate on deeper
ocean depths with increasing temperatures
of the crude oil as a consequence. Precisely
here, the combination of ROCKWOOLs
capability to resist high temperatures and
good insulating qualities appears.
Aquaduct has already been used success-
fully in Sub-Sea projects world wide for se-
veral years. We offer individual and custom-
ised solutions to match the specific condi-
tions and needs: Pipe-in-pipe system, Pipe
Bundles, Field Joints and Bespoke solution.
