It is crucial tohave the needed fire protection andit is getting more and moreimportant to have a high levelof sound and thermal insulation.See page 15-40 for A-constructionsSee page 73-76 for sound insulationSee page 77-80 for thermal insulationDiscoThe discothèque, cinema and barareas onboard cruise ships are bigsources of noise. It is important to have theright sound insulation around these areastowards the neighbouring areas.See page 15-40 for A-constructionsSee page 63-66 floating floorSee page 73-76 for sound insulationCorridorsCorridors are part of the emergencyescape routes on a vessel.The numbersof horizontal fire zones passed by the corridordetermine the fire insulation class.See page 15-40 for A-constructions
  • 5. 55Marine&OffshoreInsulation-anoverviewEngine roomThe engine room contains a lot of fire risks sofire protection is essential.The engine room isalso source of high and often disturbing noise.It is often filled with pipes, tanks, containers andother equipment where technical insulation isrequired. It is important to have the insulationprotected so oil vapour does not get into theinsulation material.See page 15-40 for A-constructionsSee page 67-72 for technical insulationSee page 73-76 for sound insulationSee page 93 for surfacesOffshoreOn offshore applications you have more or lessthe same conditions as on a ship. Furthermoreyou have the risk of hydrocarbon fire and needto protect people and material from an HC fire.See page 41-50 for H-constructionsSee page 51-54 for Jet Fire and Blast ResistancePublic areaThe public area is requiring all kindsof insulation, depending on the situation.See page 15-40 for A-constructionsSee page 60 for draught stoppersSee page 73-76 for sound insulationSee page 77-80 for thermal insulationSee page 93 for surfacesStairwaysThe stairways are part of the emergencyescape routes on a vessel.The numbersof vertical fire zones passed by the stair-way determine the fire insulation class.See page 15-40 for A-constructionsGalleyIn the galley you always have a risk of fire,as you have a mixture of heat and flam-mable materials. In this case it is alsonecessary to be aware of the facings asyou have oil vapour in the air.See page 15-40 for A-constructionsSee page 67-72 for technical insulationSee page 93 for surfacesControl roomIn the control room fire is to be held out aslong as possible as this is the last place whereall the technical equipment can be controlled.The sound level needs to be low, as enginecrew has to spend a lot of time here. It ismoreover important that no vapour gets tothe machines and computers and that theroom has a reasonable sound level.See page 15-40 for A-constructionsSee page 73-76 for sound insulationSee page 93 for surfaces
  • 6. 6InsulationinGeneralInsulation in GeneralFig. 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 ratedconstructions the position of pins must follow the official drawings.Fig.3A.Using an electrical saw tocut large amounts ofRockwool productsWhen cutting large quantities of Rockwool insulation it is recommendedto use an electrical saw.This will ensure a good and angular surface thatis easy to tighten against the next Batts/Slabs. 2-5 mm oversize is recom-mended.The pieces of insulation should be min. 150x150 mm.Fig. 3C. Using a shear to cut Wired MatsWired Mats should be cut with a large shear. 2-5 mm oversize isrecommended.The pieces of insulation should be min. 150x150 mm.Fig. 2. Painting of the plateTo avoid corrosion the plate can afterwards be painted with anticorrosion paint.Fig. 3B. Using a Rockwool knife to cut Rockwool InsulationRockwool insulation can easily be cut with a Rockwool knife or asimilar sharp knife.When the Batts/Slabs are cut in 2-5 mm oversize(depending on density) the optimal tension and tightness can beobtained when fitting the wool.The pieces of insulation should bemin. 150x150 mmPREPARATIONCUTTINGThe installation of insulation material can be donein different ways. It is up to the insulation contractorto choose the best way for each application. For firerated constructions the installation has to follow theofficial drawings according to the fire test. Drawingscan be found on our website, www.rockwool-marine.com. In the following you will find a general descrip-tion of the way the insulation work can be done:
  • 7. 7InsulationinGeneralFig. 6 Fixing the insulationFix washers on the pins in order to secure fixing of the insulation.Alternative 1, fig. 4A. Insulation of stiffenersDepending on the construction it is recommended to start with theinsulation of the stiffeners. First by filling out the space, behind thestiffener, with Rockwool insulation.The insulation should fit exactly tothe profile structure.Afterwards insulate around the stiffener with therequired thickness of Rockwool insulation.Alternative 2, fig. 4A. Insulation between stiffenersDepending on the construction it can be easier to start with insulationof the plate. Joints must be tight and no air gaps must be found. Inconnection with solutions with more than one layer of insulation, thejoints should be staggered by min. 150 mm to ensure that no joints gostraight through both layers.Alternative 1, fig. 5A. Insulation between stiffenersInsulate the plate between stiffeners with Rockwool insulation. Jointsmust be tight and no air gaps must be found. In connection withsolutions with more than one layer of insulation, the joints should bestaggered by 150 mm to ensure that no joints go straight throughboth layers.Alternative 2, fig. 5A. Insulation of stiffenersInsulate with Rockwool insulation around the stiffener. Fill out thespace behind the stiffener with Rockwool insulation, the insulationshould fit exactly to the profile structure.INSTALLATION
  • 8. 8InsulationinGeneralSecuring the productWhen installing the insulation all pieces must be fit firmly with mini-mum one pin approx 10 mm longer than the nominal thickness of theinsulation. On A-constructions the material has to be fastened withspring washers.Different pinsSteel pins are used for steel decks and bulkheads.The steel pins arecoated with copper for corrosion protection. Stainless steel pins withaluminium tip are used for aluminium constructions.The pins arenormally 3 mm in diameter and can be aquired in different lengths.WashersThe spring washers used to slide over the pins for securing theinsulation should be 38 mm in diameter and of corrosion protectedmaterial.Securing H-constructionsOn H-constructions it is recommended that the pins are approx40 mm longer than the nominal thickness of the insulation and arebent in different directions to ensure that the wool is secured. In caseof H-constructions use of wire mesh as a cover is recommended. OnH-constructions the material has to be fastened with spring washers.Covering the steel washersThe washer can be fit with a plastic cap to cover the steel tip andto create a nice looking surface.SECURING THE PRODUCTPINSWASHERS
  • 9. 9InsulationinGeneralUsing tape to ensure an airtight surface between two battsAll joints must be sealed with a tape width of 75-100 mm to ensurean air tight surface. Make sure that there is no grease on the surfacebefore the tape is applied. Pins and washers should be taped.Stacking of Rockwool productsThe products must not be stacked in more than two layers whendelivered on pallets.They must only be stored on the flat side whendelivered in packages and must not be stacked in heights of morethan three metres. It is recommended that roll products are stackedupright.Do not sit on the Rockwool materialThe products must at all times during storage remain untouchedand must not be affected by any kind og treading, sitting or anyother similar kind of exposure.Storage of Rockwool insulationThe products must at all times be stored dry indoor in closed ware-house facilities.STORAGE AND STACKINGIn 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 coldersurfaces, it will often lead to problems with corrosion. If it is oil vapourthis will be collected in the wool and endanger the fire properties ofthe wool.To close the surface on the Rockwool products there areseveral options e.g. reinforced alu foil:• All joints must be sealed with a tape width of 75-100 mm to ensurean air tight surface.• Make sure that there is no grease, oil or dirt on the surface beforethe 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 usedfor marine applications.In order to secure the right conditions for storage ofRockwool Marine & Offshore products a special set ofconditions have been prepared, e.g. the products:• Must at all times be stored dry indoor in closed warehousefacilities.• Must not be stacked in more than two layers when deliveredon pallets.• Must only be stored on the flat side when delivered in packagesand must not be stacked in heights of more than three metres.• Must at all times during storage remain untouched and must not beaffected by any kind of treading, sitting or any other similar kind ofexposure.• Must be transported in closed compartments, e.g. trailers, contain-ers and other cargo holds in order to avoid exposure to weatherelements and/or condensation etc.VAPOUR BARRIER
  • 10. 10Calculation of MaterialsBelow you will find a rough guidance for estimated need of material. Check your drawings for moredetailed calculations.INSULATIONIN GENERAL THE CUSTOMER IS ALWAYS RESPONSIBLE FOR CALCULATIONSPINS AND WASHERSTAPE WASTEBased on a total amount of insulationfor plate + stiffeners:The plate equals 60%.The stiffeners equals 40%Alternatively the use of pins and wash-ers can be calculated by the total area ofplate and stiffener in m2times min. 18.Example:A total quantity of 100 m2plate needs tobe insulated; also taking the insulationof stiffeners into consideration.Estimated need of pins and washers:100 m2x 18 pins/m2= 1800 pinsAs guidance the following amount ofwaste has to be included:Insulation area < 100 m210 % wasteInsulation area > 100 m25% wasteCalculationofMaterialsBased on a plate of X m2. The amountof Batts/Slabs for stiffeners can asguidance be calculated as X times 0.7Example:100 m2of plate needs to be insulated.Calculation of material for stiffener:100 m2x 0.7 = 70 m2111 122As guidance the use of pins andwashers can be calculated as follows:Plate in m2times min. 12.Stiffener in m2times min. 10.Example:100 m2insulation of plate requires100 m2x 12 pins/m2= 1200 pins100 m2insulation of stiffeners requires100 m2x 10 pins/m2= 1000 pinsAs guidance the amount of tape forjoints can be calculated by theinsulated in m2times 4 stated inrunning metresExample:Tape for 100 m2of insulation;100 m2x 4 m/m2= 400 metres
  • 11. 11Choosing the Right ProductTo find the correct product it is necessary to knowwhich application 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 insulationWhen the application is known, the requirements forproduct characteristics need to be evaluated e.g.:• Fire properties• Sound properties• Thickness• Thermal conductivity• Mechanical strengthIn some applications the weight could be of impor-tance. In such cases the lighter products can bechosen, but it is not always the lightest solution thatgives the best result. The light products do not protectagainst noise in the same frequency band as themore heavy products, so here it is necessary to knowwhat result is requested in the end.All Rockwool products have good fire properties, butwhen using the products on ships or offshore rigs itis necessary to choose the right product fulfilling theneeded fire rating.Furthermore it can be relevant to evaluate the differ-ent solutions with regard to the working and instal-lation method. Depending on the experience, thelabour cost and the prioritisation it might be relevantto include parameters as e.g.:• Easy handling• Less cutting• Fast installation• Labour intensity0575/yearRockwool Marine & Offshore has a large number ofcertificates for the different products and applica-tions from classification companies based on fire testsmade at IMO approved fire institutes.When choosing a product it is necessary to choose aproduct that is approved by the classification com-pany that has to approve the application/newbuildingin the end.Some customers prefer to work with constructionsbased on Batts, securing easy handling of small sizeand fixed products, others prefer to work with con-structions based on Wired Mat. For some customers itis important to have the best and most safe solutionstypically based on a two layer solution where othercustomers tend to focus on easy and fast installation.Finally, it is important to focus on the rightdocumentation such as:• Type approvals• Type certificatesWhen using Rockwool insulation onboard a vesselcarrying an EEA flag make sure that the product hasthe MED approval symbol (wheelmark).It is important to make sure that the products andconstructions have the right approval needed in thespecific project, e.g. construction approval, non-combustible approval and low flame spread approval.Remember to check if the certificate is valid at thetime where the insulation plan is approved by theclassification societies.Choosing the Right ProductTo find the correct product it is necessary to knowChoosingtheRightProduct
  • 12. 12RequirementsforFireInsulationRegulations for Fire InsulationAccording to SOLASThe requirements for materials and construc-tions to meet specified standards of safety arenormally prescribed by international or nationallaws related to shipping and offshore installa-tions.In addition to these regulations classificationsocieties such as Det Norske Veritas (DNV) andLloyds Register of Shipping (LRS) may have ad-ditional requirements.Approvals and Certification• Suppliers of materials and constructions to themarine and offshore industry must prove that theirproducts, as a minimum, meet the statutory require-ments.• The MED directive (EC Council Directive 96/98/EC - Marine Equipment Directive) has replacedthe previous approvals from the maritime authori-ties within EEA countries. All products supplied tomarine carrying EEA flag must be subject to theMED directive.• MED-certificates are issued bynotified bodies accredited by anEEA country. Approved productsbear the mark of conformity.• Classification societies issue type approval certifi-cates stating the permission to use specific mate-rials and constructions together with any relativerestrictions.• If there are special circumstances or requirementsfor special details, it may be required to obtainstatements from other authorities.Approval Requirements• To satisfy the national authorities and classifica-tion societies, materials and constructions must beproven to comply with the national and internationalrequirements. Tests have to been done at interna-tionally recognised test laboratories.• The tests have to be performed so that the materialsor products are exposed to a fire generated undercontrolled conditions that simulate as closely as pos-sible a worst case scenario.Test Requirements• There are several national and international require-ments regarding the use of materials on shipsand offshore installations. These classifications arerequired to prove combustibility characteristics andinclude ignition properties, heat release and devel-opment of toxic gases and smoke.• To prove that materials meet the required firetechnical classification, tests are carried out atrecognised test institutions according to standard-ised test methods.Material Test Methods.Testing of material’s fire resistance is done accordingto FTP code for non-combustibility and where afacing is applied for low flame spread. The most com-monly accepted test methods are:• Non-Combustibility:IMO A-799(19)ISO 1182• Low Flame Spread:IMO A-653(16)It is important to note that materials which meet therequirements for non-combustibility do not have to betested for other fire technical properties.Construction Test MethodsTesting of a construction’s fire resistance (decks, bulk-heads, structural steel, penetrations etc.) is normallycarried out in a standardised test furnace, where theconstruction specimen is exposed to a fire accordingto a standardised time/temperature curve.The most common test methods are:• Recommendation on Fire Test Procedures for “A”,“B” and “F” Class Divisions. IMO A-754 (18)§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 refrigeratedcompartments of service spaces.Vapour barriers and adhesives used in conjunction with insulation,as well as the insulationof pipe fittings for cold service systems,need not be of non-combustible materials,but they shall be kept to the minimumquantity practicable and their exposed surfaces shall have low flame-spread characteristics.”
  • 13. 13RequirementsforFireInsulationClass B Fire Divisions• Class B fire divisions must be of non-combustible materials andmust prevent the propagation of flames for at least 30 minutesduring a standard fire test.• The divisions must be insulated so that the average temperatureon the unexposed side of the division does not exceed 140°Cabove the initial temperature.• Furthermore, the temperature at any single point on theunexposed side must not exceed 225°C above the initialtemperature within the time limits.Class A Fire Divisions• Class A fire divisions must be of non-combustible materialsand insulation materials must be fire tested at a recognisedinstitution.They must be sufficiently braced and must preventthe propagation of flames and smoke for a minimum of onehour during a standard fire test.• The divisions must be insulated so that the average temperatureon the unexposed side of the division does not exceed140°C above the initial temperature.• Furthermore, the temperature at any single point on theunexposed side must not exceed 180°C above the initialtemperature within the time limits.Class H Fire Divisions• Class H fire divisions must be of non-combustible materialsand insulation materials must be fire tested at a recognizedinstitution.They must be sufficiently braced and must preventthe propagation of flames and smoke for a minimum of twohours during a standard fire test for a hydrocarbon fire.• The divisions must be insulated so that the average temperatureon the unexposed side of the division does not exceed 140°Cabove the initial temperature.• Furthermore, the temperature at any single point on theunexposed side must not exceed 180°C above the initialtemperature within the time limits.Notified BodyRockwool Marine & Offshore is cer-tified according to the MED directive.As notified body we have chosenDet Norske Veritas which alsoguaranties our quality by runningaudits.Fire Classifications of DivisionsClass B-3030 minutesClass B-1515 minutesClass B-00 minutesClass A-6060 minutesClass A-3030 minutesClass A-1515 minutesClass A-00 minutesClass H-120120 minutesClass H-6060 minutesClass H-00 minutes2x
  • 14. 1414SymbolGuideOne layer solutionThe construction is based on a solution where theconstruction is made with one product in one layer.This leads to faster installation.Low construction weightThe construction is based on products with a lowdensity and/or low thickness which lead to low totalconstruction weight.Fast installationThe construction is based on Mats which reducethe cutting especially around stiffeners, andconsequently faster installation time.Safe solutionThe construction is based on a multiple, typical twolayer solution which results in more safe solutionsespecially due to staggered joints.Optimal sound propertiesThe construction is based on products with higherdensity and/or more thickness which result in bettersound properties.Easy handlingThe construction is based on Batts, where the smallsize and fixed structure of the products give an easyhandling in respect to cutting and installation.SYMBOL GUIDERockwool Marine & Offshore has made symbols forall fire rated applications explaining the advantageswith each application:Symbol Guide

  • 64. FloatingFloorConstructionsFloating Floor ConstructionsClass A-60MED-B-2302 includes two different types ofA-60 Deck class Floating Floor constructions.1) Rockwool Marine Slab 200This solution consists of two layers Rockwool MarineSlab 200, each of 30 mm thickness, covered by mini-mum 2 mm steel plate, spot welded at c/c 150 mm.This construction combines the excellent propertiesof fire protection, noise reduction, high compressionstrength and thermal insulation.The max free area recommended is 8 x 8 m. If largerfree areas are to be made, division flat bars shouldbe made. This allows the insulation to stay in posi-tion without the need of gluing. It is recommendedto make full overlap of the two layers. All joints of theMarine Slabs have to be tight butted joints. Smallerweld marks, dents, etc. of an approx max diameter of50 mm and 10 mm height will be absorbed.If the deck is undulating, an approved self levellingcompound or floor screed will have to be used as firstlayer; a fire retardant PE compound, cement basedfiller or similar. If a water based floor screed orlevelling compound is used, it must be given suffi-cient time to cure before the floating construction isinstalled. It is very important to ensure not to encap-sulate water/moisture, as this will enhance corrosionand limit the expected life time of the construction.64The top layer has to be made of minimum one layerof 2 mm steel plate, according to the fire approvals.Final floor covering has to be decided based uponrequirements for mechanical strength and floor finish.As flooring solution, this one is a “safe” solution, in thesense that a Rockwool Marine Slab of 200 kg/m3isvery ridged and strong, and combined with amedium thick steel plate this is normally adequatefor all normal accommodation load.
  • 65. FloatingFloorConstructions2) Marine Slab 140This solution consists of one layer of Rockwool MarineSlab 140, 60 mm thickness, covered by minimum1.5 + 3 mm steel plate. The construction gives inaddition to the excellent properties of fire protection,noise reduction and thermal insulation, also reductionof structural noise/vibrations in the steel deck.Rockwool Slab 140 has been designed with focus onthe dynamic stiffness, i.e. best possible noise reduc-tion. Please note that the compression strength of thissolution is lower than the Marine Slab 200 solution.The first layer of steel plate must be 1.5 mm thick,installed with 50 mm overlap and secured with poprivets. The second layer(top layer) must be 3 mmsteel plate with butted joints and spot welded at c/c150 mm. Top covering has to be decided based uponrequirements for mechanical strength and finish.65Rockwool Marine & Offshore is preferred supplier for many marineflooring companies.These companies integrate the Rockwool prod-ucts in their more sophisticated solutions.Sealing of edges to prevent structural noiseEnclosing:For the perimeter of the construction it is recom-mended to finish the insulation with a rigid Rockwoolproduct i.e. Rockwool Marine Slab 140 or 200 placededgeways and sealed with a flexible sealant.Many of the flooring companies are using RockwoolMarine Slabs in densities of 140 - 200 kg/m3, in com-bination with more complex top layers. The max loadfor the complete flooring construction will dependentirely on the top layer. The load capacity of the spe-cific construction is to be calculated and tested by theflooring company.Rockwool Marine & Offshore is preferred supplier formany dedicated marine flooring companies. Thesecompanies then create more sophisticated solutionsfor superb noise reduction in both high and low fre-quencies.Note: Deviations from the certified A-60 floating floor constructionin any form, could require new approval by the Class Society orNational Marine Authority.

  • 68. 68TechnicalinsulationPrincipally, a thermal insulation structure for pipingconsists of an appropriate insulating material, usuallycovered by sheet metal cladding. This protects thepipe and the insulation from external influences suchas weather or mechanical loads.Spacers are also essential with insulation materialsuch as wired mats, which do not offer sufficient re-sistance to pressure to hold the weight of the claddingand other external loads. These spacers transfer theloads from the cladding directly onto the pipe to beinsulated. In case of vertical piping, support struc-tures are fitted to take on the loads of the insulationand the cladding. In general, support structures andspacers form thermal bridges.HVAC Insulation - PipesFor the HVAC (Heat Ventilation Air Condition) appli-cations onboard a ship it is most common to use PipeSections or Marine Lamella Mats to insulate the pipes.The aim is to prevent heat loss in heating systems andwarm water supply. It is necessary to supply heatingand warm water also in the last cabin away from thesource.AirductsToday, many requirements are made on air ducts.Most important is that the comfort on board the ves-sels or platform living quarters is considered and thatno compromises are made to the demands on firesafety. In connection with ventilation of cabins andother rooms it must furthermore be ensured that nocondensation is formed and that the required tem-perature is maintained all the time. This is obtained byusing one of the Rockwool Marine & Offshore prod-ucts in the correct thickness. Thickness calculationprogram 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 limita-tions (e.g. temperature, viscosity, pressure, etc.). In addition to the correct isometric construction and fasteningof the piping, the piping insulation also has an important function. It must ensure that heat losses are effectivelyreduced and that the installation continues to operate economically and functionally on a permanent basis. This isthe only way to guarantee the maximum efficiency of the process cycle throughout the design service life withoutlosses as a result of faults.The benefits of correct thermalThe benefits of correct thermalinsulation for piping include:insulation for piping include:• Reduction of heat losses• Cost savings• Reduction of CO2emissionsemissions• Frost protection• Process control:ensuring the stability of the process temperatureensuring the stability of the process temperature• Noise reduction• Condensation prevention• (Personal) Protection against high temperatures(Personal) Protection against high temperaturesTechnical InsulationTechnical Insulation in General
  • 69. 6969TechnicalinsulationMultiple Layers• Where there is a requirement for more than onelayer of Pipe Section, it is recommended that bothlayers should be banded to ensure a consistentlytight fit of the insulation.• The outer layer(s) of the section should be appliedwith staggered joints, both laterally and longitudi-nally.Insulation withPipe Section• Generally, the best insulation is achieved by usingRockwool Pipe Section. The Pipe Sections can beused up to max. service temperatures of 620°C acc.to EN 14707. Facing max. 80°C. The Pipe Sectionsare supplied ready split and hinged for quick andeasy snap-on assembly and are suitable for thermaland acoustical insulation of pipe work.• Their excellent fit and high compression resistancemean that Pipe Sections can be applied in a singlelayer without any additional spacers. Consequentlythe number of thermal bridges, which have a nega-tive influence on the insulation, is greatly reduced.Banding• Rockwool recommends that the Pipe Section is se-cured to the pipe by applying three steel bands persection length, with the end bands approximately100mm from the lateral joints.• If wire ties or spiral binding are to be used, theyshould only be considered on pipe sections with anouter surface diameter of 200 mm or less.In those cases, there should be:• At least three wires tie per section.• Spiral binding must be per section(i.e. tied off at each end of each pipe section).
  • 70. 7070Technicalinsulation• Marine Lamella Mat 32 consists of stone wool lamel-las placed edgewise, the majority of the fibres be-ing perpendicular to the facing. The Marine LamellaMats can be used up to max. service temperaturesof 250°C. Facing max. 80°C.• Due to the alignment of the Rockwool fibres inMarine Lamella Mats, they have a high resistanceto compression. They are suitable for applicationswhere there is a requirement for:• Compression resistance• Possible mechanical impact• Operational vibration loads• The surface finish on the Marine Lamella Mats,should be taped at all joints.• The mats are secured with steel banding.• Marine Lamella Mat 32 consists of stone wool lamel-• Due to the alignment of the Rockwool fibres in• Possible mechanical impact• Operational vibration loadsElbows/Bends• To form insulated elbows with Pipe Section, thesection is cut at angles to form segments.• The amount of segments depends on the size of thepipe and the angle of the elbow.• When the pipe section segments are fit around thepipe, they are secured with steel banding or wireties per section.• Any minor gaps between segments can be filledwith pieces of Rockwool insulation.Insulation withMarine Lamella Mat
  • 71. 7171• Marine Wired Mat is a lightly bonded stone woolmat faced with a galvanised wire mesh. The WiredMats can be used up to max. service temperaturesof 680°C acc. to EN 14706. Facing 80°C.• Due to their flexibility and high temperature resist-ance, Marine Wired Mats can easily be cut andfixed onto the piping.• Marine Wired Mats have a relatively low resist-ance to pressure and from a practical point of viewshould only be installed in combination with spac-ers. Due to the thermal bridges of this combina-tion the better insulation performances are oftenachieved in the lower and middle temperaturerange with Marine Pipe Sections rather than withMarine Wired Mats.Fixing• Any gaps created by the type of support ringinstalled, must be filled with loose Rockwool.• The Marine Wired Mats are secured to the pipe bystitching the edges of the wire mesh together withbinding wire or by clipping the mesh together withC-Hooks.• On pipes with a diameter greater than 350 mm,steel straps or additional pins and spring washersare applied on the underside of the pipe, it may benecessary to prevent sagging.• On vertical pipes, the wire mesh of each mat mustbe tied to the support ring above.Multiple Layers• Where there is a requirement for more than onelayer of Marine Wired Mat, it is recommended thatall layers are stitched or clipped to ensure a consist-ently tight fit of the insulation.• The outer layer(s) of mat should be applied withlongitudinally staggered joints and whereapplicable, with staggered joints laterally.TechnicalinsulationThese wired mats are ideal for application in situations wherethe use of Pipe Sections is difficult or impossible:• Temperatures above 300°C• Pipe diameters ≥ ø350 mm• Piping with a high number of shaped pieces suchas elbows or T-joints.Insulation withMarine Wired Mat
  • 72. 7272CladdingSuitable cladding should be applied to protect theinsulation from weather influences, mechanical loadsand (potentially corrosive) pollution. Selecting the ap-propriate cladding depends on various factors, suchas working loads, wind loads, ambient temperaturesand conditions.When selecting the appropriate cladding, take thefollowing points into account:• As a general rule, galvanised steel more thanaluminium is used indoors due to its mechanicalstrength, fire resistance and low surface tempera-ture (in comparison to an aluminium cladding).• In corrosive environments like outdoors on deckwhere salty water leads to corrision, aluminisedsteel, stainless steel or glass reinforced polyester(e.g. Rocktight) is used as cladding. Stainless steelis recommended for use in environments with a firerisk.• The surface temperature of the cladding is influ-enced by the material type. The following appliesas a general rule: the shinier the surface, the higherthe surface temperature.• To exclude the risk of galvanic corrosion, only usecombinations of metals that do not tend to corrodedue to their electrochemical potentials.• For acoustic insulation, a noise absorbent mate-rial (Lead layer, polyethyten foil) is installed on theinsulation or inside the cladding. To reduce the riskof fire, limit the surface temperatures of the claddingto the maximum operating temperature of the noiseabsorbent material.Technicalinsulation• Tanks and vessels can be insulated with RockwoolMarine Slabs/Batts min. density 45 kg/m3if there areno requirements for high operational temperatures.The products can be used up to max. service tem-peratures of 250°C.• The Marine Slabs/Batts are installed over metalstrap ties. These ties are bent over the edge of theouter layer of Marine Slabs/Batts to retain themagainst the tank wall.• Where the insulation extends more than 4 m inheight, intermediate support profiles must beinstalled onto the tank wall. Special “S”-profiles canbe used to ensure vertically staggered joints, whilesupporting the Marine Slabs/Batts above and retain-ing the Marine Slabs/Batts below.• When more than one layer of Marine Slabs/Batts isrequired, all joints must be staggered and tightlybutted together to avoid thermal bridges.• The Marine Slabs/Batts must be covered with a flator profiled external cladding to protect them fromthe weather and mechanical damage.Insulation withMarine Slabs/Batts

The sound absorption depends onthe thickness of the material. The values at the lowfrequencies are improved with increased thickness.The same tendency can be obtained by moving theabsorbers away from the base.Protection of the absorber by a cover plate does notchange the absorption as long as the plate has a suffi-cient number of openings. A perforation of 15% couldbe sufficient for a 1 mm thick cover plate of steel.Thicker covers require a larger number of smallholes.Sound

Since the sound reduction maybe different at different frequencies, test measure-ments are subjected to a standard procedure whichyields a single number that is about equal to theaverage sound reduction in the middle of the humanhearing range. The weighting procedure is standard-ized in ISO 717-1 for the sound reduction of airbornenoise.Rw, R’w: weighted sound reduction index, dBR’w(dB) is the weighted apparent sound reductionindex in a building, including flanking sound trans-mission.

  • 78. 78The requirements of the indoor climate andcomfort have become more stringent duringthe recent years.The insulation constitutes animportant factor of this, as it ensures that thecorrect temperature is obtained.The most common way of expressing thermal prop-erties is by using the following nomenclature:• Coefficient of the Thermal Transmission(U-value)• Thermal Resistance (R)• Thermal Conductivity (λ)It is important to note that the λ-value for any givenmaterial varies with temperature.Specification of the λ-value should therefore bereferred to as “mean” temperature and, if possible, toa standardised method for measurement and calcula-tion.Solutions forThermal Insulation1: Thermal insulation can be used alone where thereis no other demand for the deck and bulkhead.2: Thermal insulation can also be used together withfire insulation or sound insulation.When the minimum insulation thickness has beenfound for protecting against sound or fire, thethermal transmission (U-value) of this material canbe calculated from the λ-value. If a higher insulationlevel is requested the construction can be im-proved by adding an extra layer of a lower densityproduct.In all cases of insulating towards cold temperaturesthe wool must always be covered by a vapour tightsurface. This surface can be aluminium foil or anotherkind of vapour barrier. The gaps should be tightlysealed with alu tape.When adding additional insulation to a fire construc-tion it should be documented and approved by thelocal surveyor.Thermal InsulationThermalInsulationFloor connectionWhen making a surface towards the exterior it isnecessary to end the insulation 50 mm above thefloor. This to make sure that condensate from thebulkhead can be drained away.In front of the gab, a piece of flat iron can be fit to guide thecondensate to a drain.

  • 80. 80Lambda value/thermal conductivity ()The lambda() value, also referred to as thermalconductivity, is a value indicating how well a mate-rial conducts heat. It indicates the quantity of heat(W), which is conducted through 1 m2wall, in athickness of 1 m, when the difference in tempera-ture between the opposite surfaces of this wallequals 1 K (or 1°C). In practice  is a numericalvalue expressed in terms of W/(mK).

  • 93. 93SurfacesPlain Rockwool:This is the basic Rockwool product which is approved andsuitable for almost any purpose.The products are based onstone wool which can withstand temperatures above 1,000°Cwithout melting.Wired Mat with wire mesh:Some of our fire rated constructions are based on Wired Matand the wire mesh can form an additional safety to securethe product.Within technical insulation a Wired Mat if oftenused for high temperatures applications or if you need tobend the insulation around e.g. a pipe.Wired Mat with reinforced aluminiumfoil and wire mesh:This surface has the same properties as the Wired Mat buthas further more the property of securing a dust free surface.Reinforced aluminium foil:The reinforced aluminium surface will be the best solutionif you need a vapour barrier.The product will secure thatno vapour will enter the product and result in corrosion ofsteel and damaged wool.Glass cloth:This surface has three major properties: impact resistant, dustfree surface and a nicer outlook.This surface will in many casessave the use of an extra metal cladding as the woven cloth isstrong enough to resist most impact from the surroundings.Black glass tissue:The thin black tissue is often used in ventilation shafts orbehind a perforated plate as it secures a dust free surfaceand a nice outlook.White glass tissue:The thin white surface will secure a dust free surface.The white/transparent look will give a bright surface.SurfacesThere are many reasons for choosing insulation products with facings. In most cases it is done to obtain a vapourbarrier, which prevents formation of condensation on the cold side of a construction. If vapour is the reason forchoosing a new surface Rockwool markets different products with reinforced aluminium foil. In other cases it isnecessary to have a better look than the pure wool; Rockwool markets different surfaces such as glass tissue andglass cloth. If the need is to secure the product then a surface with wire mesh might be to prefer.ROCKWOOLWIRED MAT REINFORCED ALUWIRED MATREINFORCED ALUGLASS CLOTH - 200 g/m2(GW200) + 400 g/m2(GW400)GLASS TISSUE BLACKGLASS TISSUE NATURAL/WHITE

  • 96. 96Health and Safety - Green PassportScientific research of man-made mineral fibres goesback to 1930; to the beginning of the production ofthese fibres, which has expanded enormously ina wide range of insulation applications since. Thegrowth in the use of mineral fibres - also known asMan-Made Vitreous Fibres (MMVFs) - has meant thatscientists have needed to describe the effects onpublic health. Independent institutes worldwide have,consequently, been carrying out extensive animal andepidemiological studies of mineral (glass, rock andslag) wool workers for more than seventy years.Rockwool Marine & Offshore is part of the RockwoolGroup and one of Rockwool’s largest R&D projectsever resulted in the high-alumina low-silica woolgeneration. This is a quality wool with higher bio-solubility as a result of its chemical composition (seebox) and thus a wool with an increased safety marginin comparison with traditional mineral wool.Roxul®1000 fibers are world wide exonerated fromany classification. The product quality of this woolis, of course, consistently high, retaining all technicalfeatures.Green PassportAll Rockwool Marine & Offshore stone wool insulationmaterials for the marine and offshore market, pro-duced at any of the European Rockwool productionplants, will NOT be classified as hazardous materialsin relation to the mentioned IMO resolution guidelineA.962(23).
