1 Bridge

At the bridge it is important to secure a

high level of fire protection and sound

insulation. See page 21-53 for A-Constructions

See page 77-79 for Floating Floor

See page 87-93 for Sound Insulation

2 Corridors

Corridors are part of the emergency

escape routes on a vessel. The numbers

of horizontal fire zones passed by the

corridor determine the fire insulation

class.

See page 21-53 for A-Constructions



3 Storage and tank rooms

In the boiler room, storage rooms and

tank rooms it is often important to insu-

late surfaces, boilers and pipes.

See page 73 for Penetrations

See page 81-86 for Technical Insulation

4 Engine room

The engine room contains a lot of fire

risks so fire protection is essential. Theengine room is also source of high and

often disturbing noise. It is often filled

with pipes, tanks, containers and other

equipment where technical insulation

is required. It is important to have the

insulation protected so oil vapour does

not get into the insulation material.




See page 111 for Surfaces

5 Control room

In the control room fire is to be held out

as long as possible as this is the last

place where all the technical equipment

can be controlled. The sound level needs

to be low, as engine crew has to spend a

lot of time here. It is moreover important

that no vapour gets to the machines and

computers and that the room has a rea-

sonable sound level.


See page 87-93 for Sound Insulation See page 111 for Surfaces

6 Disco

The discothèque, cinema and bar areas

onboard cruise ships are big sources of

noise. It is important to have the rightsound insulation around these areas

towards the neighbouring areas.




7 Cabins

On board a passenger ship it is essential

to have the right insulation between the

cabins. It is crucial to have the needed

fire protection and it is getting more and

more important to have a high level of

sound and thermal insulation.




8 Stairways

The stairways are part of the emergency

escape routes on a vessel. The numbers

of vertical fire zones passed by the stair-

way determine the fire insulation class.


9 Galley

In the galley you always have a risk of

fire, as you have a mixture of heat and

flammable materials. In this case it is

also necessary to be aware of the facings

as you have oil vapour in the air.




10 Public area

The public area is requiring all kinds of

insulation, depending on the situation.


See page 72 for Draught Stoppers


See page 95-98 for Thermal Insulation


11 Offshore

On offshore applications you have more

or less the same conditions as on a ship.

Furthermore you have the risk of hydro-

carbon fire and need to protect people

and material from an HC fire.

See page 55-62 for H-constructions

See page 63-66 for Jet Fire and

Blast Resistance

Insulation in General

Fig. 1. Welding of pins to the plate (bulkhead/deck).

As first step the pins must be welded to the plate and stiffener.

Distance between pins should not exceed 300 mm. For fire rated con-

structions the position of pins must follow the official drawings.

Fig.3A. Using an electrical saw to cut large amounts of ROCKWOOL

SeaRox products.

When cutting large quantities of SeaRox insulation it is recommended

to use an electrical saw. This will ensure a good and angular surface

that is easy to tighten against the next Slabs. 2-5 mm oversize

is recommended. The pieces of insulation should be min.150x150 mm.

Fig. 3C. Using a scissors to cut Wired Mats

Wired Mats should be cut with a large shear. 2-5 mm oversize is

recommended. The pieces of insulation should be min. 150x150 mm.

Fig. 2. Painting of the plate.

To avoid corrosion the plate can afterwards be painted with anti

corrosion paint.

Fig. 3B. Use a ROCKWOOL knife to cut ROCKWOOL SeaRox Insulation

ROCKWOOL SeaRox insulation can easily be cut with a ROCKWOOL

knife or a similar sharp knife. When the Slabs are cut in 2-5 mm

oversize (depending on density) the optimal tension and tightness can

be obtained when fitting the wool. The pieces of insulation should be

min. 150x150 mm

PREPARATION

CUTTING

The installation of insulation material can be done in different

ways. It is up to the insulation contractor to choose the best

way for each application. For fire rated constructions the

installation has to follow the official drawings according to

the fire test. Drawings can be found on our website,

www.rockwool-rti.com. In the following you will finda general description of the way the insulation work can be

done:

Fig. 6 Fixing the insulation

Fix washers on the pins in order to secure fixing of the insulation.

Alternative 1, fig. 4A. Insulation of stiffeners

Depending on the construction it is recommended to start with the

insulation of the stiffeners. First by filling out the space, behind the

stiffener, with SeaRox insulation. The insulation should fit exactly to

the profile structure. Afterwards insulate around the stiffener with the

required thickness of SeaRox insulation.

Alternative 2, fig. 4A. Insulation between stiffeners

Depending on the construction it can be easier to start with insulation

of the plate. Joints must be tight and no air gaps must be found. In

connection with solutions with more than one layer of insulation, the

joints should be staggered by min. 150 mm to ensure that no joints go

straight through both layers.

Alternative 1, fig. 5A. Insulation between stiffeners.

Insulate the plate between stiffeners with SeaRox insulation. Joints

must be tight and no air gaps must be found. In connection with solu-

tions with more than one layer of insulation, the joints should be stag-

gered by 150 mm to ensure that no joints go straight through

both layers.

Alternative 2, fig. 5A. Insulation of stiffeners

Insulate with SeaRox insulation around the stiffener. Fill out the space

behind the stiffener with SeaRox insulation, the insulation should fit

exactly to the profile structure.

Securing the product

When installing the insulation all pieces must be fit firmly with

minimum one pin approx 10 mm longer than the nominal thick-

ness of the insulation. On A-constructions the material has to be

fastened with spring washers.

Different pins

Steel pins are used for steel decks and bulkheads. The steel pins are

coated with copper for corrosion protection. Stainless steel pins with

aluminium tip are used for aluminium constructions. The pins are

normally 3 mm in diameter and can be aquired in different lengths.

Washers

The spring washers used to slide over the pins for securing the insula-

tion should be 38 mm in diameter and of corrosion protected material.

Securing H-constructions

On H-constructions it is some times required that the pins are approx

40 mm longer than the nominal thickness of the insulation and are

bent in different directions to ensure that the wool is secured.

The additional application of wire mesh is not needed when using new

SeaRox H-constructions because the wire mesh is already part of ourWired Mat. On H-constructions the material has to be fastened with

spring washers.

Covering the steel washers

The washer can be fit with a plastic cap to cover the steel tip and to

create a nice looking surface.

VAPOUR BARRIER

STORAGE AND STACKING

Max height

3 m

R

Using tape to ensure an airtight surface between two batts

All joints must be sealed with a tape width of 75-100 mm to ensure

an air tight surface. Make sure that there is no grease on the surface

before the tape is applied. Pins and washers should be taped.

Stacking of ROCKWOOL SeaRox products

The products must not be stacked in heights of more than three

metres.

Do not sit on the ROCKWOOL SeaRox material

The products must at all times during storage remain untouched

and must not be affected by any kind og treading, sitting or anyother similar kind of exposure.

Storage of ROCKWOOL SeaRox insulation

The products must at all times be stored dry indoor in closed ware-

house facilities.

In rooms where vapour will enter the insulation as a reason of tem-

perature/ pressure differences, a vapour barrier is often a demand.

When water vapour is moving from the hot room towards colder

surfaces, it will often lead to problems with corrosion. If it is oil vapour

this will be collected in the wool and endanger the fire properties ofthe wool.

To close the surface on the ROCKWOOL SeaRox products there are

several options e.g. reinforced alu foil:

All joints must be sealed with a tape width of 75-100 mm to ensure

an air tight surface.

Make sure that there is no grease, oil or dirt on the surface before

the tape is applied. This will cause the tape to come loose.

Make sure all holes in the surface are closed.

The surface must have a low flame spread approval if it is used

for marine applications.

In order to secure the right conditions for storage of ROCKWOOL

marine and offshore products a special set has of conditions been

prepared, e.g. the products:

Must at all times be stored dry indoor in closed warehouse

facilities.

Must not be stacked in more than two layers when delivered

on pallets.

Must only be stored on the flat side when delivered in packages and

must not be stacked in heights of more than three metres.

Must at all times during storage remain untouched and must not be

affected by any kind of treading, sitting or any other similar kind of

exposure.

Must be transported in closed compartments, e.g. trailers, contain-

ers and other cargo holds in order to avoid exposure to weather

elements and/or condensation etc.

Choosing the Right Product

To find the correct product it is necessary to know which ap-

plication it has to be used for e.g.:

Fire insulation

Sound insulation

Thermal insulation

Insulation of technical installations

Floating floor insulation

Panels

Insulation of sub-sea pipelines

Combinations e.g. fire and sound insulation

When the application is known, the requirements for product

characteristics need to be evaluated e.g.:

Fire properties

Sound properties

Thickness

Thermal conductivity

Mechanical strength

Water repellency

In some applications the weight could be of importance. In

such cases the lighter products can be chosen, but it is not

always the lightest solution that gives the best result. The light

products do not protect against noise in the same frequency

band as the more heavy products, so here it is necessary to

know what result is requested in the end.

All ROCKWOOL SeaRox products have good fire properties,

but when using the products on ships or offshore rigs it is

necessary to choose the right product fulfilling the needed

fire rating.

For marine and offshore application it is relevant also to

choose for the product with the best properties within water

repellency. All ROCKWOOL SeaRox products have very low

water absorption which secure the best product properties

also in the future.

Furthermore it can be relevant to evaluate the different soluti-

ons with regard to the working and installation method.

0575/year

Depending on the experience, the labour cost and the

prioritisation it might be relevant to include parameters

as e.g.:

Easy handling

Less cutting

Fast installation

Labour intensity

ROCKWOOL Technical Insulation has a large number of certi-

ficates for the different products and applications from clas-

sification companies based on fire tests made at IMO approved

fire institutes.

When choosing a product it is necessary to choose a product

that is approved by the classification company that has to ap-

prove the application/newbuilding in the end.

Some customers prefer to work with constructions based on

Slabs, securing easy handling of small size and fixed products,

others prefer to work with constructions based on Wired Mats.

For some customers it is important to have the best and most

safe solutions typically based on a two layer solution where

other customers tend to focus on easy and fast installation.

Finally, it is important to focus on the right documentation

such as:

Type approvals

Type certificates

When using ROCKWOOL SeaRox insulation onboard a vessel

carrying an EEA flag make sure that the product has the MED

approval symbol (wheelmark).

It is important to make sure that the products and construc-

tions have the right approval needed in the specific project,

e.g. construction approval, non-combustible approval and low

flame spread approval. Remember to check if the certificate is

valid at the time where the insulation plan is approved by the

classification societies.

To secure the highest safety level on-board also remember tocheck if the product and construction are tested according to

the latest standard fire test procedure, IMO 2010 FTP Code.

15


16/116

Regulations for Fire InsulationAccording to SOLAS

The requirements for materials and constructions to meet

specified standards of safety are normally prescribed by in-

ternational or national laws related to shipping and offshoreinstallations.

In addition to these regulations classification societies such

as Det Norske Veritas (DNV) and Lloyds Register of Shipping

(LRS) may have additional requirements.

Approvals and Certification

Suppliers of materials and constructions to the

marine and offshore industry must prove that their prod-

ucts, as a minimum, meet the statutory requirements.

The MED directive (EC Council Directive 96/98/EC - Marine

Equipment Directive) has replaced the previous approv-

als from the maritime authorities within EEA countries.

All products supplied to marine carrying EEA flag must be

subject to the MED directive.

MED-certificates are issued by

notified bodies accredited by an

EEA country. Approved products

bear the mark of conformity.

Classification societies issue type approval certificates stat-ing the permission to use specific materials and construc-

tions together with any relative restrictions.

If there are special circumstances or requirements for spe-

cial details, it may be required to obtain statements from

other authorities.

Approval Requirements

To satisfy the national authorities and classification socie-

ties, materials and constructions must be proven to complywith the national and international requirements. Tests

have to be done at internationally recognised test labora-

tories.

The tests have to be performed so that the materials or

products are exposed to a fire generated under controlled

conditions that simulate as closely as possible a worst case

scenario.

Test Requirements

There are several national and international requirements

regarding the use of materials on ships and offshore instal-

lations. These classifications are required to prove combus-tibility characteristics and include ignition properties, heat

release and development of toxic gases and smoke.

To prove that materials meet the required fire technical

classification, tests are carried out at recognised test

institutions according to standardised test methods.

Material Test Methods

Testing of material’s fire resistance is done according to the

latest FTP code for non-combustibility and where a facing is

applied for low flame spread.

It is important to note that materials which meet the require-

ments for non-combustibility do not have to be tested for other

fire technical properties.

All ROCKWOOL A- and H-constructions are tested accord-

ing to FTP-code. FTP-code is describing also the thickness

of the test specimen. The decision about the thickness of the

structural part is in responsibility of the ship designer and will

finally be approved by the responsible class society.

Construction Test Methods

Testing of a construction’s fire resistance (decks, bulkheads,

structural steel, penetrations etc.) is normally carried out in a

standardised test furnace, where the construction specimen

is exposed to a fire according to a standardised time/tempera-

ture curve.

IMO 2010 FTP Code

As of 1st July 2012 a new fire test procedure within the

marine sector, IMO 2010 FTP Code, came into force. The test

procedures have been revised in order to maintain the highest

practical level of safety as well as the harmonisation of certi-

fied test institutes to the same level.

SOLAS, Chapter II-2, Regulation 5.3.1:

Use of non-combustible materials

“Insulating materials shall be non-combustible,

except in cargo spaces, mail rooms, baggage

rooms and refrigerated compartments of service

spaces. Vapour barriers and adhesives used in

conjunction with insulation, as well as the

insulation of pipe fittings for cold service

systems, need not be of non-combustible

materials, but they shall be kept to the minimum

quantity practicable and their exposed surfaces

shall have low flame-spread characteristics.”

16


17/116

Class B Fire Divisions

Class B fire divisions must be of non-combustible materials

and must prevent the propagation of flames for at least 30

minutes during a standard fire test.

The divisions must be insulated so that the average tem-

perature on the unexposed side of the division does not

exceed 140°C above the initial temperature.

Furthermore, the temperature at any single point on the

unexposed side must not exceed 225°C above the initial

temperature within the time limits.

Class A Fire Divisions

Class A fire divisions must be of non-combustible materials

and insulation materials must be fire tested at a recognised

institution. They must be sufficiently braced and must pre-

vent the propagation of flames and smoke for a minimum of

one hour during a standard fire test.

The divisions must be insulated so that the average temper-

ature on the unexposed side of the division does not exceed

140°C above the initial temperature.

Furthermore, the temperature at any single point on the

unexposed side must not exceed 180°C above the initial


Class H Fire Divisions

Class H fire divisions must be of non-combustible materials

and insulation materials must be fire tested at a recognized

institution. They must be sufficiently braced and must pre-

vent the propagation of flames and smoke for a minimum of

two hours during a standard fire test for a hydrocarbon fire.

The divisions must be insulated so that the average tem-

perature on the unexposed side of the division does not

exceed 140°C above the initial temperature.

Furthermore, the temperature at any single point on theunexposed side must not exceed 180°C above the initial

New Constructions;New Standard for Safety

IMO 2010 FTP CodeAs of 1st July 2012 a new fire test procedure within the

marine sector, IMO 2010 FTP Code, came into force. The testprocedures have been revised in order to maintain the highest

practical level of safety as well as the harmonisation of certi-

fied test institutes to the same level.

To fulfill the new requirements ROCKWOOL Technical

Insulation has developed and tested a new range of PFP

(Passive Fire Protection) constructions. The use of our new

constructions ensures compliance with the latest standard in

the market; IMO 2010 FTP Code.

As first step ROCKWOOL Technical Insulation has introduced a

range of new constructions which cover the main solutions

for A-rated steel passive fire protection constructions:

A-30 Steel Bulkhead and Deck

A-60 Steel Bulkhead and Deck

A-60 Steel Bulkhead restricted

Main advantages:

Future-proof constructions - tested

according to the latest standard

Optimized logistics - main

constructions possible with only

one product in two dimensions

Uniform pin design for all

constructions

New SeaRox Product Rangeand Optimized Logistic As part of the introduction of new solutions ROCKWOOL

Technical Insulation has at the same time used the

opportunity to optimize the SeaRox product assortment

and simplify the range of constructions.

All 5 main constructions can be insulated with only one

product in two dimensions:

SeaRox SL 620, 30 mm and 50 mm.

This new and optimized SeaRox

product range offers more

efficient logistics with less items

to stock and easier handling

from design to installation.

New Certificates

The range of new fire ratedconstructions has been

approved by our notified body,

Det Norske Veritas, and new

certificates have been issued.

To clearly distinguish between

constructions which have been

tested according to either the old or new FTP Code, all new

constructions are issued on separate certificates. As existing

certificates tested according to the old standard expire, they

will be phased out.

To find our new MED-certificates andto be updated on the status of new

certificates please visit our website:

www.rockwool-rti.com.

Existing certificateswill still be validafter the implemen-

tation of the newtest methods.

One layer solution

The construction is based on a solution where the

construction is made with one product in one layer.

This leads to faster installation.

Low construction weight

The construction is based on products with a low

density and/or low thickness which lead to low total

construction weight.

Fast installation

The construction is based on Mats which reduce

the cutting especially around stiffeners, and

consequently faster installation time.

Safe solution

The construction is based on a multiple, typical two

layer solution which results in more safe solutions

especially due to staggered joints.

Optimal sound properties

The construction is based on products with higher

density and/or more thickness which result in better

sound properties.

Easy handling

The construction is based on Slabs, where the small

size and fixed structure of the products give an easy

handling in respect to cutting and installation.

Low water absorption

The construction consists of products with low water

absorption which secure and maintain optimal

product properties.

ROCKWOOL Technical Insulation has made symbols for all

fire rated applications explaining the advantages with each

The regulatory requirements for the blast behaviour offire rated bulkheads are not normally well documented.

It is considered a general requirement that all parts of fire

divisions maintain the same fire and explosion resistance

and proof of this must be documented through physical

testing.

All the above tests were carried out without any significant damage to the insulation material.According to the Norwegian Fire Research Laboratory (SINTEF) a fire will not affect the fire integrity or stability of the insulation.

Due to the test methods used, SINTEF has assessed the above results to be conservative.

ROCKWOOL, in association with SINTEF (NBL) in Norway, has performed extensive testing on H-rated ROCKWOOL insulation

systems, using controlled gas explosions. The test results below refer to the same insulation construction with various types of

wire mesh.

Solas requires that the stiffeners must be insulated*. One way

is to insulate without filling the space behind the stiffeners.

In other situations the insulation can follow the shape of the

stiffener or the void behind the stiffener can be filled

out.

If the stiffener is more than 450 mm wide the insulation can

be stopped at 450 mm. The insulation of stiffeners should be

finally approved by local surveyor.

In most bulkhead and deck constructions stiffeners are used to secure the necessary strength in the construction. In order to

prevent heat transmission it is important to secure the right insulation. In general insulation of the stiffeners must follow the

official drawings as carried out in the fire tests.

Bulkhead and Deck Connections

When two plates are connected in a corner, the heat bridge should always be kept in mind when insulating. The structure

must have insulation so that heat transfer can not occur from one unexposed surface through the structure and onto another

unexposed surface. The heat must always go minimum 450 mm under the insulation before reaching an unexposed surface(acc. to SOLAS MSC/circ. 1120 annex reg. 9.3.4).

Bulkhead and Deck - Construction details

In connection with insulation it is important to pay special attention to the details related to junctions, corners etc. in order to avoid

potential heat bridges. Below you will find examples of construction details:

Connections between

A-60 and A-0 construc-

tions should be insulated

by adding a layer of

A-60 insulation on the

A-0 construction in a

minimum width of 450

mm. This is to minimize

the effect of the heatbridge.

Another alternative to insulate the heat bridge can be done

by installing min. 450 mm* of insulation on the other side

of the construction.

This will reduce thetransferred heat and

thereby minimise the risk

of self ignition inside the

connecting room.

Installation of Surface Steel Plate

A surface protection of sheet metal can be installed in

different ways, depending on the layout of the stiffeners and

the amount of insulation.

It is important to make the fixing in a way that minimises the

heat bridges and structural noise transmitted via the hull.

Draught Stoppers

Draught stoppers are used above ceilings to avoid the spread

of smoke and flames in case of fire. Normally the classifica-

tion companies request a B-0 fire insulation above the ceiling.This can be made from SeaRox WM 640 or SeaRox SL 620 after

request from the local surveyor or the customer.

Construction

SeaRox WM 640, min. 50 mm, with reinforced aluminium foil

or...

SeaRox SL 620, min. 60 mm, with reinforced aluminium foil.

SeaRox SL 620 must be covered with wire mesh. Insulation

fixed with ø3 mm pins and secured with ø38 mm washers.

Installation

Step 1: First the pins are welded vertically to the underside of

the deck in alignment with the required position of the

Draught Stopper.

Step 2: The pins are then bent 90° in a staggered pattern as

shown.

Step 3: The ROCKWOOL product and wire mesh are then

pushed over the pins so that they protrude by a mini-

mum of 25 mm. The insulation is secured by spring

steel washers.

Penetrations Penetrations through the Draught Stopper are simply made

by cutting out the shape of the penetrating items in the

ROCKWOOL product, for example, pipes, HVAC ducts and

cable racks.

The cut edge of the Wired Mat must fit tightly to the edge of

the penetrating item and the slit in the insulation must be

stitched/taped back together using steel wire/alu tape.

This solution can be used for any type of penetration includ-

ing multiple penetrations.

“Air spaces enclosed behind ceilings, panelling or linings shall

be divided by close-fitting Draught Stops spaced not more

than 14 m apart. In the vertical direction, such enclosed air

spaces, including those behind linings of stairways, trunks,

etc., shall be closed at each deck.“

Penetrations

Penetrations of fire protection

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 900

mm. IMO suggests to use min. 450 mm on each side of the

construction.

The min. 900 mm insulation must have the same insulation

class weight as the structure that is penetrated.

Fire Protection ofSprinkler Pipes

New amendment to SOLAS regulation about protection

of sprinkler pipes on passenger vessels

Seen in the light of the increasing sizes of passengerships and growing number of passengers, an amendment

to SOLAS regulation „Safe return to port“ is applicable to

all passenger ships built on or after 1st July 2010 stating

that sprinkler pipes on passenger vessels need to remain

operational in case of fire.

The amendment is valid for:

All passenger ships of 120 m or more, or...

Having three or more main vertical zones

Applicable also for ROPAX vessels and large offshoreaccommodations.

Floating Floor Constructions Class A-60

MED-B-7488 includes two different types of A-60 Deck class

Floating Floor constructions.

1) SeaRox SL 480

This solution consists of two layers SeaRox SL 480, each of

minimum 30 mm thickness, covered by minimum 2 mm steel

plate, spot welded at c/c 150 mm.

This construction combines the excellent properties of fire

protection, noise reduction, high compression strength and

thermal insulation.

The max free area recommended is 8 x 8 m. If larger free

areas are to be made, division flat bars should be made. This

allows the insulation to stay in position without the need of

gluing. It is recommended to make full overlap of the two

layers. All joints of the Slabs have to be tight butted joints.

Smaller weld marks, dents, etc. of an approx max diameter of

50 mm and 10 mm height will be absorbed.

If the deck is undulating, an approved self levelling compound

or floor screed will have to be used as first layer; a fire retard-

ant PE compound, cement based filler or similar. If a water

based floor screed or levelling compound is used, it must be

given sufficient time to cure before the floating construction

is installed. It is very important to ensure not to encapsulate

water/moisture, as this will enhance corrosion and limit the

expected life time of the construction.

Min. 2 mm Steel Top Plate

30 mm

30 mm

SeaRox SL 480, 2 layers

Steel Deck Plate

The top layer has to be made of minimum one layer of 2 mm

steel plate, according to the fire approvals.

Final floor covering has to be decided based upon require-

ments for mechanical strength and floor finish.

As flooring solution, this one is a “safe” solution, in the sense

that a SeaRox SL 480 of 200 kg/m3 is very ridged and strong,

and combined with a medium thick steel plate this is normally

adequate for all normal accommodation load.


79/116

2) SeaRox SL 436

This solution consists of one layer of SeaRox SL 436, minimum

60 mm thickness, covered by minimum 1.5 + 3 mm steel plate.The construction gives in addition to the excellent properties

of fire protection, noise reduction and thermal insulation, also

reduction of structural noise/vibrations in the steel deck.

SeaRox SL 436 has been designed with focus on the dynamic

stiffness, i.e. best possible noise reduction. Please note that

the compression strength of this solution is lower than the

SeaRox SL 480 solution.

The first layer of steel plate must be 1.5 mm thick, installed

with 50 mm overlap and secured with pop rivets. The second

layer(top layer) must be 3 mm steel plate with butted joints

and spot welded at c/c 150 mm. Top covering has to be de-

cided based upon requirements for mechanical strength and

finish.

ROCKWOOL Technical Insulation is preferred supplier for many ma-

rine flooring companies. These companies integrate the ROCKWOOL

products in their more sophisticated solutions.

For the perimeter of the construction it is recommended

to finish the insulation with a rigid ROCKWOOL product i.e.

SeaRox SL 436 or SeaRox SL 480 placed edgeways and sealed

with a flexible sealant.

Many of the flooring companies are using ROCKWOOL SeaRox

Slabs in densities of 140 - 200 kg/m3, in combination with more

complex top layers. The max load for the complete flooring

construction will depend entirely on the top layer. The load

capacity of the specific construction is to be calculated and

tested by the flooring company.

ROCKWOOL Technical Insulation is preferred supplier for

many dedicated marine flooring companies. These companiesthen create more sophisticated solutions for superb noise

reduction in both high and low frequencies.

Note: Deviations from the certified A-60 floating floor construction in

any form, could require new approval by the Class Society or National

Marine Authority.

Technical Insulation


82/116

Principally, a thermal insulation structure for piping consistsof an appropriate insulating material, usually covered by

sheet metal cladding. This protects the pipe and the insula-

tion from external influences such as weather or mechanical

loads.

Spacers are also essential with insulation material such as

wired mats, which do not offer sufficient resistance to pres-

sure to hold the weight of the cladding and other external

loads. These spacers transfer the loads from the cladding

directly onto the pipe to be insulated. In case of vertical pip-

ing, support structures are fitted to take on the loads of the

insulation and the cladding. In general, support structures

and spacers form thermal bridges.

HVAC Insulation - Pipes

For the HVAC (Heat Ventilation Air Condition) applications

onboard a ship it is most common to use Pipe Sections or

SeaRox Lamella Mats to insulate the pipes. The aim is to

prevent heat loss in heating systems and warm water supply.

It is necessary to supply heating and warm water also in the

last cabin away from the source.

Airducts

Today, many requirements are made on air ducts. Most

important is that the comfort on board the vessels or plat-

form living quarters is considered and that no compromises

are made to the demands on fire safety. In connection with

ventilation of cabins and other rooms it must furthermore be

ensured that no condensation is formed and that the required

temperature is maintained all the time. This is obtained by

using one of the ROCKWOOL Technical Insulation products in

the correct thickness. Thickness calculation program can be

found on our webpage.

To guarantee a correct process cycle, the condition of the media within the pipes must remain within the set limitations (e.g.

temperature, viscosity, pressure, etc.). In addition to the correct isometric construction and fastening of the piping, the piping

insulation also has an important function. It must ensure that heat losses are effectively reduced and that the installation con-

tinues to operate economically and functionally on a permanent basis. This is the only way to guarantee the maximum efficiency

of the process cycle throughout the design service life without losses as a result of faults.

The benefits of correct thermal insulation for piping include:

Reduction of heat losses

Cost savings

Reduction of CO2 emission

Frost protection

Process control: ensuring the stability of the process

temperature

Noise reduction

Condensation prevention

(Personal) Protection against high temperatures

Multiple Layers

Where there is a requirement for more than one layer of

Pipe Section, it is recommended that both layers should be

banded to ensure a consistently tight fit of the insulation.

The outer layer(s) of the section should be applied with
