Substrate designations are:Galvalloy - S220GD+ZA (1995) from BS EN 10214Galvatite - Fe E220 G from BS EN 10147

Coated ProductsThe customer can be certain that the product has beencomprehensively tested and evaluated by the extensive researchand development facilities of our suppliers.

These products have been developed over many years, for avariety of applications, and therefore have different performancecharacteristics. The descriptions that follow are aimed atdistinguishing those differences.

Pre-coated products for exterior roofing and cladding arecomposed of a steel substrate having a metallic coating,pre-treatment, and primer on both sides, with a paint topcoat onthe weatherside and a polyester coating on the reverse side(commonly referred to as the backing coat). There are differentmetallic and organic coatings for particular applications.

Aluminium Facings

IntroductionMill finish and colour coated aluminium facings are available in a range of specifications and colours to suit specific projectrequirements.

When specifying aluminium faced insulated panels it is vital thatKingspan Technical Design Bureau is involved to assist thedesign team regarding material, coating specifications, productand application issues.

Aluminium SubstrateKingspan Insulated Panels are manufactured from the followingmaterial substrate grades; Material alloy grades:-

• 3003 series• 3004 series• 3005 series

The external facing is produced in aluminium alloy containingmanganese and magnesium for increased strength and rigidity.The alloy is cold rolled to achieve the required temper and, when necessary, partially annealed to improve ductility and finish,or may be coated for decorative effect. Mill finish surfaces may be plain or stucco embossed. Coatings will normally be applied to plain surfaces.

The range of external coatings systems available are:-

Coating System Thickness Microns Gloss % Range

PVDF 25 35%

Abrasion Resistant28 30%

(A.R.S.)

Polyester 22 30%

The standard internal facing is in white polyester coated, plain orstucco embossed aluminium.

CoatingsAluminium is both stable and durable. In the majority ofenvironments it will provide excellent service as roofing or wallcladding without the need for a protective coating. However, thereare a few applications where the metal requires protection against aparticularly aggressive environment. There are also a number ofother reasons why a user may choose to specify a coating system.

Colour may be required in order to match existing buildings, tocomply with planning requirements, or to conform with the ‘housecolours’ of the customer. Some military establishments must becamouflaged, and colour coated claddings can help to achievethis effect. Infra-red reflectant paint can be a further aid in thisrespect. Newly installed aluminium has a highly reflective surface,and although this weathers rapidly there are a few applicationswhere this may be undesirable (e.g. close to airfields). In suchcases a coating system can be used to reduce dazzle.

The coated aluminium system is a complex, multi-layerarrangement. The integrity and performance of the total systemdepends on the proper selection of all the component parts.

The system comprises:-

• Substrate • Pretreatment• Primer • Top Coat

The combination of corrosion resistance, strength to weight ratioand good surface finish makes aluminium the ideal substrate.Because aluminium rarely requires protection against corrosion, the coating may be selected for its decorative qualities - thiscontrasts directly with steel substrates for which a protectivecoating is vitally important.

PretreatmentThis is the first stage of the coating process. The aluminiumsubstrate is cleaned, degreased and given a chromated coating.This not only enhances corrosion protection, but also provides anexcellent key for the coatings which will be applied subsequently.This process is rigorously controlled and monitored to ensure thatprecise, uniform coating weights are applied.

Although this coating is only a few microns in thickness, it is thevital interface between the decorative finish and the substrate. The success of the entire coating system is heavily dependent on the pretreatment process.

Coil Coating SystemThe coating system can consist of a single layer of decorativecoating, but some systems comprise two or more layers.

In multi-layer systems it is usual to apply a primer over thepretreatment coating. The primer is selected for adhesion,corrosion resistance and flexibility. The top coat is then selectedfor visual appearance.

Each coat is applied, in liquid form, by rollers. The coil is passedthrough an oven to cure the coating.

For particular finishes where a metallic appearance is required it maybe necessary to apply a further lacquer to give added protection.

Aluminium Facings

PerformanceCoating systems vary considerably in performance, and respond indifferent ways to the various environmental influences. Thespecification of the coating system must take account ofperformance priorities, and of local environmental characteristics.

External ConditionsThe two important external influences are ultra violet radiation andchemical pollution. The chemical pollution may be from very localsources, or may arise from a major industrial conurbation.

Ultra Violet RadiationRadiation may be sub-divided into three main categories. Ultra violet (A&B) covers a band of wavelengths from 285nm to 400nm, and accounts for 6% of all radiation. Visible light, in the band from 400nm to 780nm, accounts for 50% of radiation.The remaining 44% is infra red and falls into the band ofwavelengths from 780nm to 1400nm.

These proportions are typical, but there will be some variation withlatitude, season and time of day.

Ultra violet is high energy radiation, which will ultimately destroyany organic products. It has three important effects on coatingsystems. It causes loss of gloss, chalking and loss of colour.

Loss Of GlossGloss reduction must not be confused with chalking. The twophenomena may occur at the same time, but are not the same.

Loss of gloss is the first sign of degradation in the coating. It iseasily recognised, and once started it will continue until the surfacebecomes matt (unless conditions change significantly). Oncedegradation has started, the surface loses more of the ‘body’ ofthe binder. These leave a concentration of the more stablepigments, with consequent gloss loss. The process is not linear,gloss reduction usually accelerates with time.

Gloss level is measured by reference reflected light, and this isinfluenced by the angle of incidence of the light to the coatingsurface. It is necessary to specify the angle in order to obtain ameaningful comparison.

Different coating systems may behave in a very different manner inrespect to loss of gloss.

Chalking Chalking is seen as a whitening of the surface. When the surfaceis wiped a powdery degradation is shown. Cleaning and polishingcan restore the surface and the colour, but the chalking willreappear upon further exposure.

Chalking is caused by the release of non-bound powderypigments on the surface of the film. Although ultra violet is themain factor it needs a combination of humidity and oxygen topromote the reaction. The geographical areas where chalking ismost severe are warm and humid with high ultra violet, such asthe tropics.

Since the chalking will be removed by washing, there will be acontinual loss of binder. The film will become gradually thinneruntil, eventually, total loss of the coating will occur. The addition ofan ultra violet stable binder can significantly reduce this reaction.

Chalking can manifest itself in a different form in the case ofcertain binders, such as PVDF (Polyvinylidene Fluoride). Thismaterial is highly transparent to ultra violet radiation and, unlessthe correct pigments are used to inhibit the transmission of ultraviolet through the binder, the primer coat will chalk. This can leadto delamination of the PVDF from the primer.

Loss Of ColourThis is caused by bleaching of the pigments in the paint system bythe ultra violet radiation. This can be avoided by the correct choiceof pigments and, in particular, the adoption of inorganic pigments.

Chemical PollutantsChemical pollutants occur mainly in the atmosphere as acidicgases, such as sulphur dioxide (SO2), nitrogen oxides (NOx) and chlorides (Cl).

The pollutant which is the cause for greatest concern is sulphurdioxide. It is both common and aggressive. Its main source is theburning of sulphur-containing fossil fuels in power stations, and inlarge industrial and domestic conurbations. The sulphur dioxide istaken into solution by the moisture-laden atmosphere to forminitially sulphurous, and ultimately, sulphuric acid. These give riseto the formation of so-called ‘acid rain’.

The presence, and concentration, of any chemical pollutants canvary considerably from area to area depending on local conditions.It is essential that specific local details are available whenconsidering the performance of any coating system or substrate.

Internal EnvironmentThe environmental conditions inside a building can be more variedthan those outside. Chemical pollutants arising from processescarried out within the building can give rise to extreme conditions,as can humidity (probably the most severe internal condition).Aluminium substrates are very stable, and most coating systemsare suitable over aluminium. Some attention must always be givento internal conditions when choosing or specifying a suitablecoating system.

In extreme conditions, such as swimming pools, with highconcentrations of chlorine and hydrochloric acid (HCl), edgeprotection will probably be necessary.

Individual Coating SystemsPVDF, Polyvinylidene FluorideThis system is based on a mixture of the PVDF resin and acrylicresin. It is an extremely durable system, giving excellent flexibilityand chemical resistance, combined with the highest possibleperformance with respect to gloss retention, chalking and colourchange.

However, PVDF is ultra violet transparent, so the choice of pigmentsis critically important if chalking of the primer is to be prevented.The primer must, of course, receive this protection in order thatdelamination should not occur. The number of pigments which canprovide the required protection is not large; consequently the colourrange for PVDF is limited.

PVDF is not available as a high gloss product, but this is notimportant in the construction industry. Typical gloss levels for PVDFare 30%. Slightly higher figures can be achieved where necessary.

PolyesterThis is a widely used, general purpose coating system which canbe tailored to give a wide range of characteristics. Its gloss levelcan be anywhere in the range from fully matt to 80% gloss, and itsflexibility can be varied.

Polyester coatings have reasonable chemical resistance, and durability.

Abrasion ResistantThis system can be either a polyurethane or polyester resin mixedwith polyamide. The system has very good durability andweatherability. Its ultra violet performance is superior to that ofplain polyester.

The addition of polyamide gives the system a textured finish whichcan be varied in degrees of coarseness. One of the benefits of thesystem is that it gives a surface which is highly resistant to abrasion.

For most normal environments this coating system will give goodservice in both exterior and interior applications.

MetallicsMetallic effects are available in all the standard pre-coat systems(PVDF, Abrasion Resistant, Polyester). The metallic finish isobtained by the addition of metallic flakes - normally aluminium.This usually detracts from the performance of the system.

Aggressive chemical pollution such as sulphur dioxide, attacks themetallic flakes, leaving the pigment. The bright metallic is graduallychanged into a strong, non-metallic colour.

This effect may be postponed by an application of clear lacquerover the metallic coating. It is recommended that this is alwayscarried out for pre-coated systems.

Infra Red Reflective SystemsInfra Red Reflective (IRR) systems are sometimes used tocontribute to the camouflage requirements of militaryestablishments. As the characteristics are obtained by the use ofspecial, synthetic, inorganic pigments, they can therefore be usedin several binder systems, e.g. Polyester and PVDF.

The usual colours are greens and browns. These are the visiblecolours most frequently required for camouflage applications.

Textured SurfacesTextured finishes on coated aluminium can be achieved byembossing the coated metal. Typical patterns are stucco, hammer and pebble. Such finishes are not suitable for corrosiveenvironments, as the patterning may cause micro cracking in the coating.

DurabilityThe decorative and ultimate life in years is given in the table fortypical industrial environments. The figures may be extended forrural environments.

Rigid Urethane Insulation Core

IntroductionRigid urethane insulation has been used in the building andconstruction industries since the 1950’s. Over the past 40 years,in excess of 500 million square metres of insulated sandwichpanels manufactured by the continuous factory lamination processwith rigid urethane cores, have been successfully used in roofand wall cladding applications worldwide.

The superior and long term performance of metal faced insulatedsandwich panels with rigid urethane cores is now widelyrecognised by building investors and designers when comparedwith site assembled multi-part built-up cladding systems which isensuring significant growth for this type of construction.

The main reasons for this growth are:

• Increasingly stringent Building Regulations and Norms, which inmany countries demand the use of insulants to comply withenergy efficiency and CO2 emission targets.

• The rising cost of fuel and energy. Effective thermal insulationreduces HVAC plant costs, by up to 40%, whenever it is usedin industrial, commercial, institutional or domestic buildings.

• The environmental cost of energy production is also a factorwhich now needs to be considered. The burning of fossil fuelsfor energy production is estimated to contribute 80% of theworld’s CO2 emissions. These so called green-house gasescontribute to the problem of global warming, so theconservation of energy is the most direct and cheapest form ofreducing CO2 emissions and controlling global warming.

• Industry experts estimate that worldwide insulation of buildingsto optimum standards could reduce global energyrequirements by more than 10%.

• Rapid site assembly and early completion of the buildingproject is demanded by investors and insulated sandwichpanels provide ‘single fix’ fast on-site installation.

• Investors require superior specification, low maintenance andlong term lifetime products.

Thermal PerformanceRigid urethane insulation has one of the lowest thermalconductivity ratings of any insulant, which allows efficient retentionof heat, or alternatively maintenance of a refrigerated ortemperature controlled environment.

The closed cell matrix of the insulation core provides 100% certaintyof thermal reliability performance over the lifetime of the building.

EnvironmentalNon-DeleteriousThe rigid urethane insulation core used by Kingspan is CFC andHCFC free (Zero ODP) which fully complies with Montreal andKyoto Ozone Depletion Summit Protocols.

Kingspan rigid urethane insulation cores can be termed as ‘non-deleterious’.

In health terms, the products are fully cured thermoset (crossed-linked) polymers which, under normal conditions of use andtemperatures, do not emit noxious fumes and are safe to handle.

In environmental terms, the products do not emit damaging gasesnor do they leach into the environment during their lifetime. Beingsome of the most efficient insulants available for construction use,they actively contribute to the saving of energy, fossil fuels and,therefore, large scale carbon dioxide emission and global warming.

StrengthRigid urethane insulation provides a high level of compression andshear strength, which are essential requirements for insulatedsandwich panels.

AgeingInsulation faced with impermeable materials such as steel andaluminium shows minimal change in the thermal conductivity ofthe insulant over the lifetime of the installed cladding system.

Water Absorption The water vapour permeability of rigid urethane insulation is low which is also enhanced by the metal facings acting as amoisture barrier.


146


Adhesion to Facings During the period between mixing and final curing rigid urethaneinsulation is extremely adhesive, which allows it to bond effectivelyto a wide range of insulated panel facings. The adhesion is sostrong that the bond strength can be higher than the tensile orshear strength of the insulation itself.

WeightThe light weight of rigid urethane insulated sandwich panels is animportant aspect in achieving lighter and more economic mainframe design due to lower dead loads. Site assembly is also fasterand incurs lower cost due to ease of handling. Transportationcosts are also kept to a minimum due to reduced productthickness and increased load utilisation.

Chemical Resistance Rigid urethane insulation provides excellent resistance to a widerange of chemicals, solvents and oils.

Biological Resistance Rigid urethane insulation does not support fungal growth and isimmune from attack by mould, mildew and vermin infestation,these features are essential for hygiene applications.

ManufactureRigid urethane insulated sandwich panels are continuouslymanufactured under factory controlled conditions to the highestISO quality standards prior to delivery to the construction site. This guarantees a superior installed cladding system with longterm lifetime performance.

CFC & HCFC RemovalKingspan have developed and manufacture Zero ODP PIRinsulated panel systems.

When impermeable facings are present, as in the case ofKingspan Insulated Panels, the initial lambda value does notincrease significantly over the lifetime of the product.

Fire PerformanceSee Building Design Section for detailed fire performance information.

Like all organic building materials - wood, paper, plastics, paints -rigid urethane insulation is combustible, although its ignitability and rate of burning depend largely on the fire resistance propertiesof the panel facing material used in conjunction with the insulant.The most effective fire resistance can be obtained using a firerated rigid urethane insulation. Careful formulation of rigid urethanesystems makes it possible to achieve fire standards required byNational Regulations and the more demanding insurance industryrequirements.

There is an increasing requirement from building owners, insurersand building control authorities for fire rated roof and wall envelopespecification products. In response to this Kingspan havedeveloped, tested and obtained approval for a range of fire ratedproducts for roof and wall application.

Insulated panels with fire rated cores have performed well in actualfires in buildings and do not contribute significantly to the fire loadin the building, indeed they have had an excellent record as roofand wall cladding of buildings for over 40 years.

The conclusion from tests carried out in the UK, Germany, Franceand the USA all state that well designed fire rated insulatedsandwich panels have excellent fire resistant properties.

Non-Deleterious SpecificationPolyisocyanurate (PIR) Rigid Insulation - A Commentary

Non-deleterious - A Definition“Deleterious (adj) - hurtful or destructive; destructive; poisonous(from the Greek ; deleterious).” Chambers Twentieth CenturyDictionary.

Kingspan PIR rigid urethane insulation cannot be classified asdeleterious and should be termed as ‘non-deleterious’.

In health terms, the products are fully cured thermoset (crossed-linked) polymers which, under normal conditions of use andtemperatures, do not emit noxious fumes and are safe to handle1.

In environmental terms, the products do not emit damaging gasesnor do they leach into the environment during their lifetime2. Beingsome of the most efficient insulants available for construction use,they actively contribute to the saving of energy, fossil fuels and,therefore, large scale carbon dioxide emission and global warming.A modern approach to assessing this is the Total EquivalentWarming Impact (TEWI), and it can be readily demonstrated thatduring the average lifetime of construction products, the net effectis very positive, including all energy involved in raw materialproduction, fabrication, and disposal of the insulants3.

Kingspan rigid urethane insulants consist of numerous tiny closedcells bound together. These contain a gas trapped in the cellswhich assists the insulation value of the products. This gasremains within the cell during the lifetime of the products4, and canbe recovered or completely incinerated at the end of the useful lifeof the product if requested5. Following the Montreal Protocol in1987 regulating the production and use of Chlorofluoro Carbons(CFC’s) and Hydro Chlorofluoro Carbons (HCFC’s), which productshad been implicated in deterioration of the stratospheric ozonelayer, these gases are no longer used in Kingspan rigid insulants.All Kingspan products now use blowing agents that have anOzone Depletion Potential of Zero (Zero ODP).

Energy Efficiency and Pay BackThe energy saving contribution of rigid urethane PIR insulation is a very positive factor, as the fuel saved by insulation is manytimes greater than the fuel cost of producing the material initially.This can be demonstrated by the following example:

It takes 5kg of oil to produce 1 square metre of PIR wall insulationat 40mm thickness. Over a 50 year building life the insulation willsave 230kg of heating oil, so it has repaid its original cost by afactor of 46.

Working to this principle rigid urethane PIR insulation, with one ofthe lowest thermal conductivity values offers the greatest potentialfor energy saving.

ConclusionRigid urethane insulation therefore emerges as a unique material,which is perfectly suited for the insulating core of building panels.

It combines strength with a very low thermal conductivity, and its ability to bond itself to facing materials during the productionprocess makes it ideal for the mass production techniques used today.

Kingspan Insulated Panels, pre-engineered in this way, provide adurable, economic, ‘fit for purpose' roof or wall cladding solution.


Fasteners

148

IntroductionPrimary fasteners hold the insulated panels to the building frame,and secondary fasteners join panels to each other, and to flashingsetc. The fasteners are therefore an integral part of the building, andtheir strength, weatherproofing, durability, and appearance must becarefully considered as part of the overall design.

The following general notes explain the various fasteners which areused with Kingspan Insulated Panels.

Specific references from SFS Intec fasteners are within the relevantroof or wall sections for alternative fastener references contactEJOT direct.

Primary Fasteners

These fasteners are specially designed to drill through the panel,self tap into the framework, and finally seal the outer sheet.

This is achieved in one fast operation using a screwgun with adepth sensing nose piece. Various accessories for these tools areavailable from the fastener manufacturers.

Fasteners are manufactured to suit the many materials andconstructions in common use.

The variations include:

• They may be made from high quality carbon steel or austeniticstainless steel.

• The drill point alters for drilling into different materials andthicknesses.

• The self tapping thread can vary with the type and thickness of material.

• The overall fastener length will vary depending on the thicknessof the panel being fixed.

• For through fixed panels the fasteners have a secondarysupport thread directly under the head to withstandsuperimposed loads caused by foot traffic and snow. This also draws the outer skin tightly up to the washer, thus ensuring a weatherproof seal.

• The sealing washer may vary in size and material, for fixingroof, wall, or rooflights. Carbon steel, stainless steel, andaluminium washers are used in conjunction with EPDM seals.

• The fastener head may be coated metal, coated metal covered with a push-on plastic cap, or it may have an integral coloured head.

Secondary FastenersThese are the fasteners which join sheet to sheet, flashing to sheet, or flashing to flashing. The main types used are stitchingscrews or rivets.

Stitching screws self drill and tap, draw the sheets together, andfinally seal, in one operation, in the same way as the primaryfasteners. They are available in high quality carbon steel andaustenitic stainless steel, and in several head forms to suit thevarious materials being fastened.

Rivets are made from aluminium alloy and are installed in a twostage operation which involves drilling a hole through the twocomponents, pushing the rivet into the hole and setting it with a rivetting tool. This tool draws the mandrel through the rivet body and deforms it so that it grips the materials together, until it finally breaks.

Other blind fasteners are used for special applications, such as the side laps of rooflights, where normal pop rivets and stitchersare unsuitable. These larger fasteners come in several forms,some require a rivetting tool and others use a bolt to pull an EPDM grommet up to the underside of the sheet.

Installation and WeatheringSelf drilling/tapping fasteners can be supplied with a sealingwasher which is designed to prevent water ingress into thebuilding through the fixing point. To be sure of optimumperformance it is important to install the fasteners correctly.

The fasteners and washers are designed to be driven so that the washer is compressed evenly, giving the appearance shown.The screwgun is fitted with an adjustable, depth sensitive nosepiece which can be set to disengage the clutch when the fastenerhas been installed correctly.

In some cases it may be the fastener strength which limits the permissible span of the insulated panels, particularly nearjunctions on the building, where wind suction forces are high. (See the design example on page 121 in the Building Design section).

* A load factor of 2 has been used generally and 3 for the pull out values from timber in accordance with the latest revision of BS 5427.

StrengthThe Primary fasteners hold the panels in place on the building andmust be strong enough to resist the applied loads. In practice themost important load for fasteners is often wind suction which istrying to pull the panels off the building frame. In thesecircumstances ultimate failure of the fixing can happen in threepossible ways:

1. Pull OverThe outer skin of the panel deformsaround the head and washer of thefastener until the hole is largeenough for the panel to pull over,leaving the entire fastener in place.

Fastener Selector GuidesIntroductionSFS Intec manufacture large ranges of fasteners, and it is important,but sometimes quite difficult, to select the correct type for aparticular application.

To assist designers, Fastener Selector Guides are available from each fastener manufacturer which clearly identify SFS Intecor EJOT fastener references suggested for various buildingapplications and panel types.

Building ClassificationsThe following Building Classifications are used in each FastenerSelector Guide:

1. Standard EnvironmentFor normal factory or general use buildings, where theoccupants or processes do not add significant quantities of water vapour to the air.

2. High HumidityFor buildings containing large areas of open water, or wherewater is used as part of a process, e.g. Swimming pools,laundries, paper processing etc.

3. Low temperatureFor buildings where the internal temperature is often below theexternal temperature (but not less than 4° C), e.g. Chill stores,ice rinks etc.

4. Temperature ControlledFor buildings where the internal temperature or environmenthas to be closely controlled, e.g. Laboratories, specialmanufacturing processes, etc.

5. HygieneFor buildings where food is processed or a high level ofcleanliness is required, e.g. Food manufacturing/ processing,bakeries, electronic component manufacture, pharmaceutical/medical etc.

Durability and AppearanceThe ultimate life expectancy of the fasteners depends on theircorrosion rate which can be affected by their material specification,the internal and external environments, and the construction of thebuilding. However there may be appearance or performanceproblems long before ultimate failure occurs. These may be due toleakage at washers, rust staining, or faded/missing colour caps.

Corrosion can occur if there is moisture on the fastener. The rateof corrosion will depend on the fastener material, its coating, thematerials being fixed, how long the moisture is present, corrosiveelements and the ambient temperature of the environment.

From the above it is clearly difficult to make general predictionsabout the life expectancy of fasteners, however a number ofstatements can be made:

1. Coated carbon steel fasteners have performed satisfactorily onroofs and walls of insulated buildings in urban non - pollutedatmospheres for a period of 10 years, and therefore,depending upon the conditions, may be used where warrantiesup to a maximum of 10 years are required.

2. The life expectancy of an austenitic stainless steel fastener onthe same buildings would be at least 25 years and would besuitable for warranties exceeding 10 years.

3. Separate snap-on plastic colour caps may come off over time,but integral colour heads will not.

The following table shows the minimum life expectancy, andmaximum warranty period, in years for fasteners in a number ofenvironments.

Sitework Tools & Installation

To be sure of optimum performance it is important that purposedesigned tooling is used to install the fasteners correctly.

The fasteners and washers are designed to be driven so that thewasher is compressed evenly, thus ensuring a weather tight seal.The screwgun must be fitted with an adjustable, depth sensitivenose piece which can be set to disengage the clutch when thefastener has been installed correctly.

Sitework Tools & Installation

Installation InstructionsIt is essential that the self drilling fasteners are installed using theapproved power screwdriver equipped with the correctaccessories to suit the fastener and application.

Driving TechniqueThe power screwdriver must be held perpendicular to the surfaceof the material being fixed. Apply end load to engage the clutchand maintain this load while the drilling and tapping operationtakes place. The drive will disengage when the nosepiece makescontact with the surface of the material being fixed.

Setting InstructionsThe depth clutch is adjusted by pulling forward the locking collarand rotating the nosepiece. Screwing the nosepiece forward(counter clockwise) will decrease screwing depth, screwing thenosepiece back (clockwise) will increase screwing depth.

Test drive a fastener into a spare piece of material and make finaladjustments to the setting as required.

Always use good site practice when installing self drilling fasteners- wear safety goggles.

Sealants & Fillers

IntroductionSealants are a fundamental part of roof and wall claddingspecification and installation. They make an important contributionto satisfactory weathering, building physics and durabilityperformance of the cladding envelope. It is therefore vital tospecify the correct external and internal sealants and fillers at the design stage.

SealantsSealants used with Kingspan Insulated Panels can be supplied by Scapa Tapes UK Ltd or their approved distributors in two basicphysical forms:

Preformed Mastic TapesScapa Tapes 0303 and 0311 are non hardening, permanentlyflexible, synthetic butyl rubber sealants with adhesive properties.During the production process they can be formed to almost any cross sectional shape to suit particular requirements. To optimise their sealing performance and minimise water vapourtransmission rates, the tapes have to be compressed by 20%.Good adhesion can be achieved to virtually all building materials,including polyethylene.

The effective life of 0303 is more than 20 years, and 0311 will besatisfactory for 25 years.

For special applications these tapes are also available with a foamcore, allowing easy compression to fit variable width joints.Alternatively a solid pre-shim can be incorporated, ensuring thejoint can not be over tightened and force the sealant out.

These tapes are supplied on rolls with a release paper. The lengthon the roll varies with tape thickness as shown below:-

Tape Thickness mm Approx Roll Length metres

1 45

Gun Grade SealantsSilicone sealant is used exclusively with Kingspan InsulatedPanels. It is available in two basic grades:

1. 0002 Acetoxy This releases some acetic acid as it cures, and forms a relativelytough rubber which can accommodate + or - 25% joint movement.

2. 0004 Neutral cureThis low modulus silicone does not release any acid during cure, is softer than 0002, and can accommodate + or - 35% joint movement.

Both these have very good adhesion, even to glazed and othersmooth surfaces. The following table shows which grade to usewith a variety of materials.

Material 0002 0004

HPS200 Yes Yes

Plastisol Yes Yes

PVDF No Yes

Lining Enamel Yes Yes

Stelvetite Yes Yes

Aluminium Yes Yes

GRP No Yes

Glass Yes Yes

Polycarbonate No Yes

PVC No Yes

Brick No Yes

Concrete No Yes

3. 0100 Non-settlingNon-settling, non-skinning synthetic elastomers and plasticisersreinforced with inert pigments.

The sealants have a life of more than 20 years in externalapplications and joints are normally designed to allow the seal to beremoved and renewed, thus extending joint life almost indefinitely.

Sealant ApplicationsThe following table shows which materials to use in a variety ofnormal building applications.

Sealants & Fillers

When it is not possible to make a butt joint, a backing tape or gap filling foam should first be inserted into the joint, and thesealant is then applied so that it has an adequate bond area onboth sides of the joint. Generally this should be at least 6mm, but in some instances it may have to be varied to accommodatesurface profiles etc.

All surfaces must be firm, clean, dry and free from dust, dirt,grease and water to enable the sealant to adhere to them.

The surfaces should preferably be reasonably warm and neverbelow 4°C.

Gun-Grade Sealants 0002, 0004These sealants are normally used to seal around windows and doors etc.

When sealing window and door frames to the cladding it is best toarrange a butt joint, so that the sealant only bonds to the frameand the cladding. This allows the maximum amount of movementin the sealant.

Typical Ridge Filler

Clamping zed

Site appliedsilicone sealantTypical End Lap

Installation of Sealants Tape Sealants 0303, 0311:On side and end laps the location of sealant tape is as indicated.On shallow roof pitches a double line of sealant should be used or alternatively a U section sealant can be supplied.

All tapes are applied from the roll leaving the backing paper inplace to avoid stretching the tape. The paper is removed after thetape is in position. It is important that the tape is fitted properlydown the valley sides and across the troughs without stretching. If this procedure is not followed a good seal is unlikely to be made.

When placing the panels care should be taken to avoid displacingthe tape. When fixing the sheets, fasteners must not be overtightened as this could force the sealant out of the joint. Inbuildings where the internal air has a high humidity or lowtemperature, e.g. swimming pools or chill stores, the liner side ofthe panel joint must also be sealed to form a vapour barrier.


Sealants & Fillers

Scalloped Metal FlashingsScalloped metal flashings are available from Kingspan to protectweather exposed surfaces of profiled fillers from damage by birdsand to enhance the appearance of the ridge construction detail.

Fire ProtectionSealants and profile fillers are available in suitable grades for firerated requirements.

AncillariesOther sealant products may also be required for a particularbuilding and these are summarised below:-

2702 Electrical Barrier TapeWhere dissimilar metals are in contact in the presence of moisturean electrical cell can be created. This may result in rapid corrosionof one of the metals.

To prevent this the metals can be separated using a thin PVCbarrier tape.

0089 Polyurethane FoamThis insulating foam is injected from an aerosol can into a cavity,where it expands to fill the space.

Ireland:- Tex Group Ltd - Tel: (01) 6014900 Fax: (01) 6014901

Note: Other sealant and filler manufacturers’ products can be usedprovided they are equal specification and performance ofthose stated and with the approval of Kingspan.

158

Profile FillersWhere any flashings, such as at a ridge or hip are fixed to profiledroofing or cladding panels a series of gaps are created. To preventwind, rain and wildlife entering the construction these gaps needto be closed with profile fillers. The following material specificationsof profile fillers are available:

1. Flowcell 0625, is 25mm thick and cut from closed cellpolyethylene foam. This grade is available in black or white andis suitable for general use in non critical applications with aminimum life of 15 years. It should not be used in exposedapplications near the coast as it may be subjected to damageby seabirds.

2. Flowcell 0653, is cut from high density closed cellpolyethylene foam and is mainly used for rooflight constructionwhere it will have a minimum life of 15 years.

3. Flowcell 0825, is EPDM rubber foam and provides themaximum resistance to damage in adverse conditions. A 25 year design life can be expected in any application.

4. Flowcell 0726, is an EPDM faced polyethylene foam, whichhas many of the advantages of both 1 and 3 above, at anintermediate cost. It has a life expectancy of 25 years in anyapplication.

5. Flowcell 0637, is a fire retardant polyethylene fire resistant filler intended for internal use only.

6. Firestop 0740, and Cavity Barrier 0710, are cut from mineralfibre block, and will provide up to 4 hours fire resistance ininternal applications.

Fillers can be cut to fit any combinations of profiles includingangled profiles at hips, valleys and gable ends.

Profile fillers are normally supplied slightly oversized and are held inplace by light compression between the sheets. They can also besupplied with preformed mastic tape applied to either or bothfaces to seal and fix the filler in place.

Soaker Systems

Specialist contractors have developed G.R.P. Weathering, SoakerSystems to provide Solutions for any penetrations within Roof andWall applications to give excellent Weathersealing for the life of thebuilding envelope.

The innovative G.R.P. Soaker System has been used successfullyfor the past 15 years and is factory produced with the criticalinterfacing between the soaker and insulated panel systems andpenetrations created insitu, by skilled installers.

This is to ensure that a watertight seal is provided and allowsopening for penetrations to be in any location on the Roof or Wall.

In general the hole will be cut wherever required and the soaker ismanufactured to provide a good weathertight fit regardless of thelocation for the penetration, i.e. Crowns, Valley Locations of theinsulated panels.

There is no restriction to roof penetration size or relative positionthrough roof, i.e. curbs for fans, smoke vents, glazing, ducts, flues, stubs, etc. 90° to roof or floor, all are weathered within350mm of penetration.

A further advantage is that the roofing contractor will not need totake into account obstructions and can order Soakers direct withthe Specialist contractor without a detailed survey ormeasurements being necessary.

A standard range of pigments matches the standard range ofcolours, and special colours can be produced at 14 days notice.Resistance to fading or chalking is generally similar to thatHPS200 and PVDF coatings.

G.R.P. can tolerate most environmental conditions. It is notharmed by Marine conditions or industrial pollution and cantolerate higher temperatures needed at flue penetrations.

Site application difficulties have been overcome by thedevelopment of surface preparation agents and additives foradjusting the curing properties according to the weatherconditions prevailing at time of installation.

The specially developed G.R.P. Weathering Systems has beensuccessfully tested using accelerated weathering tests i.e. heatageing, water immersion, freeze/thaw cycling and UV cycling by us and approved for use on HPS200 and PVDF coatingsystems, in relation to its long term adhesion, ageing andWeathersealing performance, backed by a specialist contractorsperformance guarantee.
