INTRODUCTION

TYPESThe insulating panels produced by Isopan S.p.A. are monolithic, self-supporting sandwich panels,consisting of a layer of insulation between two facing skins. In terms of the diverse nature of thematerials used for these elements, these products can be divided into two principal families:

A1.1 THERMO-INSULATING POLYURETHANE PANELS:

THERMO-INSULATING POLYURETHANE PANELS FOR ROOFS• Isocop – 5 1000• Isoduplex 1000• Isotego 1000

THERMO-INSULATING POLYURETHANE PANELS FOR WALLS• Isotego 1000• Isopiano 1000; Isopiano 1155• Isorighe 1000• New Isoparete 1000• New flat Isoparete 1000

SINGLE-SKIN THERMO-INSULATING POLYURETHANE PANELS• Isogrecata 1000• Isodeck 40 1000• Isodoga 1000

The types of panel listed differ in respect of the external profiles of the facings, their static behaviour, theshape of the connecting joints and the uses for which they are designed. What they have in common isthe nature of the raw materials used: in particular, all the panels mentioned use an insulating layerconsisting of expanded polyurethane foam. When correctly mixed and controlled during the continuousproduction process, this confers on the product the property of outstanding thermo-insulating powerwhich is the distinguishing characteristic of this family of products.

A1.2 MINERAL WOOL INSULATING PANELS:

MINERAL WOOL PANELS FOR ROOFS• Isofire Roof 1000• Isofire Roof 1000 - Fono

MINERAL WOOL PANELS FOR WALLS• Isofire Wall 1000• Isofire Wall 1000 - Fono

A1.1

A1

The panels in these last categories are of the sandwich type, monolithic and self-supporting, consisting oftwo metal skins, in steel (or on request, aluminium, stainless or copper), connected by an insulating layerin biosoluble high-density rock wool (100 – 110 kg/m3), with fibres oriented at right angles to thebearing surfaces. This type of panel is being used increasingly frequently in the construction of roofs andpanelling for industrial and public buildings, where there is a requirement not only for good thermalinsulation properties but also for a high level of fire resistance, to comply with strict fire safetyregulations. Isofire 1000 panels have certified characteristics for reaction to fire and resistance to firewhich are such as to make the product virtually incombustible (Class 0 for the outer skin and Class 1 forthe internal insulation and fire resistance ratings of R.E.I. 30 - 60 - 120). The panels are also availablein the sound-absorbing version, with micro-perforated facing, certified for its level of sound insulationand sound absorption.

A1.3 DIMENSIONAL STANDARDSThe panels offered by Isopan S.p.A. are produced with a standard modular width of 1000 mm, or inthe case of Isopiano, 1155 mm as well. The length, on the other hand, depends on the individual designrequirements of the customer. Please bear in mind, however, that the maximum length transportable byarticulated lorry is approximately 13.5 m, and this therefore represents in practice a dimensional limit,barring transport by special carriers. The thicknesses in production normally vary from 25 mm to 150mm and even 200 mm, according to the type, the nature of the bearing surfaces and the intended use.

A1.2

RAW MATERIALS

A2.1 PRINCIPAL CHARACTERISTICS OF THE METAL FACINGS:Our panels use only top quality metal facings, with the following basic characteristics:• Steel, hot-dip galvanised by the SENDZIMIR process (UNI-EN 10147); no guarantees of resistance to

oxidisation or corrosion are offered beyond what is provided by the UNI standards or by thecorresponding European standards with regard to the gram weight per square metre of zincdeposited.

• Steel, galvanised and prepainted on continuous lines with cycles applying polyester resin, siliconisedpolyester and PVDF (polyvynilidene fluoride), on the outer side. On the inner side of the panel aprimer is applied.

• 3103 aluminium alloy with natural finish, embossed and prepainted with the cycles mentioned in theprevious paragraph. The natural aluminium facings are supplied with a primer applied to the innerside.

• Stainless steel AISI 304 (designation X5CrNi1810) to standard EN 10088-1.• Copper (for the ribbed side).• Especially in the use of facings in copper and aluminium, we recommend paying attention at the

design stage to the environmental conditions to which the product will be exposed, particularly directexposure to the sun and maximum temperatures reached, taking into account the characteristics of thematerial: in this regard, the Isopan Technical Office will be able to provide useful information toanyone who requests it.

The choice of organic coating to go with the metal facing depends on the environment in which theproduct will be installed. For explanation, please see the table below, which identifies the best coating inrelation to the environmental exposure. Isopan metal facings are required to comply with the strictestEuropean standards:• for Steel: UNI EN 10143, UNI EN 10147• for Stainless Steel: EN 10088-1, EN 10088-2• for Aluminium: UNI EN 485-4• for Copper: UNI 9329

A2.2 PROTECTION OF PREPAINTED BEARING SURFACESAll prepainted metal facings are normally supplied with a polythene film on the ribbed side, which helpsto avoid damage to the paint layer during the process of handling, transport and installation. If thematerial is specifically requested without the protective film, ISOPAN will not be held responsible for anydamage to the paintwork. On request, protection is also available on the inner side (lower face) of thepanel. The protective film covering the prepainted panels must be completely removed at the installationstage, and at all events not later than three months from the date of readiness of the materials. It isemphasised that Isopan S.p.A. will not accept responsibility for any abrasion of the prepainted bearingsurfaces attributable to the lack of the protective film (due to the load sliding during transport, forexample).

A2.3 EXPANDED POLYURETHANEThe word 'polyurethane' is normally used to denote a very heterogeneous family of plastics. Theparticular types used in thermo-insulating sandwich panels are expanded polyurethanes. An expandedmaterial is one which displays a cellular structure where the solid constituent, generally called thepolymer matrix, forms the walls of a complex of cells which may be closed or open, containing agaseous constituent of varying composition. All expanded polyurethanes are the product of the reactionof two or more liquid components which, when suitably mixed together, give rise in a relatively shorttime to the finished product.

A2.4 COMPOSITION OF THE FORMULAEGenerally speaking, polyurethanes are thought of as the product of the reaction of two componentscalled:component A = polyol mixture/polyol

component B = isocyanate

a) COMPONENT A - polyolIn addition to polyols, the polyol mixture is made up of catalysts, intermediaries to the reaction andexpanding agents.Polyols: these are particular chemical compounds characterised by the presence in their molecule of so-called hydroxide groups (-OH groups). These are oligomers with variable molecular weights andstructures. They are the product of the reaction between propylene and ethylene oxides and polyalcoholsor sugars such as saccherose and sorbitol.Catalysts: substances which act as promoters of the polymerisation and/or expansion reactionaccording to their composition. Generally these consist of aliphatic amines which are present in theformulation in relatively small quantities compared to the polyol.Stabilisers: they are generally called silicones and their function is to regulate the cell-structure as itforms, in order to obtain minimal and constant cell diameters.Fire retardants: halogenated and/or phosphorated compounds which act as flame retardants andtherefore regulate the reaction to fire of the expanded material when it is subjected to the action of flameor a source of intense radiant heat.Expanding agents: expanders in their turn may be divided into two families according to whether theexpansion involves a chemical reaction or a simple transformation of a liquid into a gas. We willtherefore speak of chemical expanders and physical expanders.

b) COMPONENT B - isocyanateComponent B is an isocyanate which normally belongs to the family of the so-called MDI polymers. Anisocyanate is distinguished by the presence in its molecule of isocyanic functional groups (NCO groups)and MDIs (diphenyl methane diisocyanates). These consist of 4,4’ diphenyl methane diisocyanate and itshigher oligomers.

A2.3

A2.5 EXPANSIONExpansion is a process which occurs at the same time as the formation of the polymer matrix and iscaused by a gas being given off during the course of the reaction. The evolution of the gas can occureither as a result of a chemical reaction, or because of a change of state in a liquid with low boiling-point. We will therefore speak respectively of chemical expanders or physical expanders. It is the latterwhich concerns us.The physical expander is represented by a liquid with a boiling-point normally below 50°C. Thepolymerisation reaction is exothermic, and causes an increase in temperature in the reacting mass andthe low-boiling expander dispersed in it.Until a few years ago, the physical expander universally used was CFC 11, because of its convenientboiling-point, its low toxicity, its reasonable price, its non-flammability and above all its excellentinsulating properties. Unfortunately, it was discovered that it bears a considerable responsibility for thedestruction of the ozone in the upper reaches of the atmosphere, where it accumulates, preciselybecause of its stability, and in conjunction with ultra-violet radiation, tends to destroy the ozonemolecules. The discovery of this negative effect on the environment led to a process of replacing it with asubstitute, under the control of strict regulations on the protection of the ozone layer.The process has now been completed, and CFC 11 and HCFC have been replaced by expanding agentswhose molecular structure no longer contains chlorine, which is responsible for the interaction with theozone. The use of pentane and its isomers represents the best compromise in the direction of full respectfor the environment. The problems relating to flammability have been satisfactorily resolved. The costshave been high, but sustainable.

A2.4

CHARACTERISTICS OF THE POLYURETHANE INSULATION

A3.1 DENSITYWhen considering the finished product, and also when considering free expansion, it is important todistinguish between total density and density at the core.‘Total density’ refers to the total volume of expanded material including the skin. In the case of asandwich panel, it is obtained by subtracting the weight of the facings from the weight of the completepanel and dividing the value obtained by the volume of the foam alone. The core density, on the otherhand, is obtained by eliminating the skin or high-density area of the foam from the calculation. Thedensity is a very important parameter because it has a direct influence on most of the physical andmechanical characteristics of the foam.

A3.2 CELL-STRUCTUREThe features of the cell-structure are the diameter of the cells, their shape and their uniformity. Talkingabout a rigid foam implies a structure which is predominantly closed-cell.The cell diameter can be estimated roughly by visual comparison with a standard sample, and assessedexactly by means of microscope images and subsequent computerised analysis. In the majority of cases,when shape and uniformity are within normal limits, the cell diameter is between 200 and 300 microns.Thermal conductivity is linked with cell diameter, but with variations which are relatively unimportant.The shape and uniformity of the cells are also characteristics which must be taken into account, as theycan be responsible for appreciable deficiencies in performance of the finished product. They are also anunequivocal index of the quality of the production process and of the correctness of the formulation.Briefly, we can say that a good cell structure is characterised by:

• a uniform appearance• absence of zones of discontinuity easily visible to the naked eye (bands of different colours)• absence of highly elongated or “stretched” cells, as they are known.

A3.3 RESISTANCE TO COMPRESSIONThe application of an external force deforms the cell-structure until it collapses completely. Normally, theresistance of a rigid foam to compression is calculated on the basis of the force necessary to induce adeformation of 10% and is expressed in kg/cm2 or in dimensionally equivalent units.In practice a test-piece of standard dimensions, generally 50x50x50 mm, is subjected to compressionbetween two flat surfaces, connected to a dynamometer, which move at a preset speed. A graph is thendrawn up in which the curve plots the deformation against the force applied. Compression resistance isaffected by the following factors:

• characteristics inherent in the formulation• the density of the foam• the orientation of the cells• the quality of the cell-structure.

Resistance to compression is a very important characteristic because it is directly linked to thedimensional stability of the foam when subjected to particular operating conditions.

A3.1

A3

Accumulated experience tells us that for a sandwich panel we need to be sure of a minimumcompression resistance of 1 kg/cm2.

A3.4 DIMENSIONAL STABILITYBy ‘dimensional stability’ we mean the capacity of the foam to maintain its dimensions unchanged overtime and in actual conditions of use. Several factors, including temperature differences, diffusion of thegas contained in the cells, permeability to air, and operating conditions, give rise to forces acting inthree dimensions which, if not adequately opposed, can lead to irreversible deformation. Generally,dimensional stability is measured by accelerated tests where samples of known dimensions are subjectedto high temperatures (70-80°C, sometimes associated with high relative humidity in the air) and lowtemperatures (-25/-30°C) for a period of time (24-48 hours or more) and the variations which the foamundergoes in the three dimensions and in total volume are recorded, expressed as percentages of theoriginal dimensions.

A3.5 REACTION TO FIRE‘Reaction to fire’ is defined as the behaviour of the foam when exposed to the action of a flame or ofradiant heat. Reaction to fire is assessed on the basis of tests which simulate exposure to fire and radiantheat, carried out on samples of fixed shape and dimensions, in accordance with strict rules, thoughthese unfortunately vary from country to country. The reaction is then observed by measurement of:

• speed of propagation and maximum height of the flame• time required for extinguishing it• area damaged• occurrence of dripping.

Reaction to fire is controlled by making changes at the formulation level, with suitable additives, and atthe level of design and manufacture of the finished product. The results of the tests, which are specific tothe individual country, are used to assign products to classes of fire resistance. It must always bespecified whether the tests concerned just the foam or the finished product.

A3.6 WATER ABSORPTIONThis is a measure of the quantity of water that the foam can absorb by direct immersion in water. Sincewe are dealing with a material with predominantly closed cells, this value is always very small (<1%). Itcan be easily verified that the only cells involved are the ones cut in the process of preparing the sample.

A3.7 THERMAL CONDUCTIVITYThe thermal conductivity of a material is its capacity to transport heat from one surface to another.It is expressed in terms of the variable λ (lambda), with W/mK as the unit of measurement. The thermalconductivity of a foam is principally linked to the composition of the gas contained in the cells, and totheir size, and also to some extent linked to the nature of the polymeric matrix. In every case, thecomposition of the gas contained in the cells is the determining factor, and we can state positively that,next after a vacuum, pentane is actually among the best insulators (7.4 mW/mK). CO2 (15.3 mW/mK)and air (25 mW/mK) turn out to be among the worst.

A3.2

A3.3

A3.8 MIXING OF THE COMPONENTSPolyurethane systems for continuous panel manufacture are generally supplied as a multi-componentsystem. It is essential to be able to adjust the expansion and catalysis to suit working conditions and thetype of panel being produced: for relatively thin panels (30-40 mm) we will have a high catalyst andexpander content, while for thick panels (120-200 mm) we will have a lower content of catalyst andexpander.A polyurethane system normally consists of the following components:

• polyol (polyols + stabilisers + fire retardant)• one or more catalysts• one or more expanders• isocyanate.

The polyol is first premixed with the expander and the catalyst. This mixture and the isocyanate are thensuitably measured out and transferred to the distribution location. It is here that the process of high-pressure mixing takes place. The temperature of the components has a considerable influence on theviscosity, and can therefore affect the quality of the mix, so it must be kept under constant control. Apoor quality mix is indicated by the presence of brown streaks, a coarse cell-structure and a ‘glassy’look to the foam.

A3.9 ENVIRONMENTThe environmental impact of the products at the present time is of large and growing importance, in asociety conscious of the need to safeguard its natural resources. The manufactured products of IsopanS.p.A. have for some time been compliant with the strictest standards and legislative requirements whichhave been enacted in this field.

As regards the polyurethane foams used, we emphasise the following characteristics:• They are self-extinguishing in terms of standard ISO 3582 (formerly ASTM 1692).• Ozone: in compliance with the limits for safeguarding the stratospheric ozone agreed by the signatory

countries to the Montreal Protocol and European regulation 3093/94.• Classified in Group 3 of the I.A.R.C. (Lyon Institute for Cancer Research) This means that the

polyurethanes come under the heading of NON-CLASSIFIABLE AGENTS as regards their capacity forcausing cancer in man and animals. (“This classification reflects the fact that the numerous testscarried out to date have not indicated any carcinogenic or mutagenic effects on man or animalsderiving even from prolonged physical contact with polyurethane foams.”)

In the case of sandwich panels with a core of rock wool, we have the following characteristics:• Biosoluble inorganic material, free of asbestos, crystalline silica and CFCs and HFCs.• Material classified in Group 3 of the I.A.R.C. (Lyon Institute for Cancer Research).

Finally, as regards the external bearing surfaces such as the metal components, we have the followingcharacteristics:• Prepainting in conformity with current Italian regulations on the contact of materials with foodstuffs

(Ministerial Decree 21/03/1973 and subsequent amendments on hygienic discipline regardingpackaging, containers and utensils intended to come into contact with foodstuffs or substances forpersonal use). This certification relates to colours Grey White, White 21, plain white similar to Ral9010 and Top Class PVC coating.

Waste disposal:in terms of current Italian legislation (Legislative Decree 22/97; Ministerial Decree 5/2/98 and updatesand amendments), the “Residues of insulating materials in C.E.R. 170604 panels” have been certified as“special non-hazardous waste” intended for recycling (R4, R13) or, here this is impossible, suitable forwaste disposal in the normal way. The Safety Data Sheet for theinsulating panels is available on request,but this is purely of an informative nature, since the product is not considered “hazardous” and does notcome within the scope of Ministerial Decree 28/01/92 (Official Gazette no. 50 of 29/02/92,supplement no. 46).

A5.2 FITTING TO ROOF (EXCLUDING ISODOGA 1000):In order to ensure that the water runs off correctly, and to avoid oxidisation of the metal supports whichcan otherwise follow, roofing panels must be laid with a minimum slope of 7%. In the case of pitchesconstructed with more than one panel lengthways, a longitudinal overlap must be provided, sufficient (inrelation to the slope) to avoid any ingress of water. In accordance with UNI 10372, ISOPANrecommends providing sufficient projection at the eaves to allow a suitable drip and prevent any ingressof water into the insulation or the inside of the building. After completing the fitting of the panels and thenecessary flashings, check carefully that no extraneous materials or residues from the job areabandoned on the roofing panels which could give rise to corrosion or prevent rainwater running offcorrectly, or cause a buildup of undesirable and harmful substances. In the accompanying illustration weshow examples of fitting roof panels in situations involving laps (overlapping longitudinal joints). Asregards flat roofs,Isopan’s recommen-dation is the Isodeck1000 panel, whichmust be laid with theribs facing downwardsand the side faced withbituminised paperfacing upwards. This inits turn is completedwith a finishingcovering in bituminousmembrane whichcompletely waterproofsthe building.

A5.3 FASTENERS ANDPRINCIPLES OF FIXINGThe type of fixingdepends on the type ofsupport used. Normally, self-tapping screws are used (also called ‘thread-forming screws’). Standardfixing is by means of 6.3 mm diameter self-tapping screws in galvanised carbon steel with hexagonheads, of the type “Kovervit BS 592”, or “592” and washer in galvanised steel incorporating a gasket inEPDM rubber to maintain the seal. If specifically requested, as an alternative to the self-tapping screwsdescribed above, ISOPAN can supply another two series of screw designated ‘self-drilling’ of type

“Kovervit 671”, which have the advantage of reducing fitting time, as the hole is drilled and the paneldirectly anchored all in one operation. These screws, which are ideal for fixing to heavy steel sections,require specialised skills for their use, and correct torque adjustment on the power screwdriver used onsite.

ISOPAN will be happy to deal with any query from customers about the various fixing systemsdescribed, their mechanical performance and their methods of use. The principles of fixing are set outbelow:

A5.3.1 Fixing for roofing panelsThe panels should be installed with the direction of laying opposite to that of the prevailing winds,checking frequently that they are parallel and correctly aligned. They should be fixed to the supportingstructure by means of the devices specified by the system, both for timber and for metal roofframeworks. The holes must have a diameter smaller than that of the fixing device; these must not befully tightened, to allow the panel to expand and contract as a result of temperature and moisturechanges. The number of fixings required varies with the local climate situation. In the course of staticdeflection tests with positive and negative loads, we have defined the “normal density” for fixings as:one bolt on alternate ribs on the central purlins and one on every rib on the end purlins. This density hasbeen assumed as standard in determining the positive and negative overload threshold. The minimumfixing density is therefore one fixing on alternate ribs in the continuous part of the roof and one fixing onevery rib round the perimeter of the sheets, and in particularly windy areas, in the central part as well.

A5.3.2 Fixing for wall panelsThe panels must be anchored to continuous metal sections running at right angles to the direction of thepanels themselves, and these members in their turn must be adequately secured to the loadbearingstructure of the building in accordance with the conditions specified in the design as regards stability.The width of the support in contact with the panel must be not less than 50 mm. In the case of an end-to-end joint between two panels, the contact width must be 80 - 100 mm. The minimum width of thesupport area at the end of each panel must be an effective 30 mm in contact with the supporting framemembers. The panels should be fixed to the loadbearing structure by means of the fasteners specified bythe system. The number of fixings varies in accordance the different climatic situations in which thebuilding may be located. Normally, every panel requires the use of one fixing opposite each supportingmember. In areas which are particularly exposed to the action of the wind, the density of the fixings mustbe determined by the designer case by case, appropriately increasing the number of fixings from thestandard specification.

The weight of the packs varies, not only with the thickness of the insulation, but also with the length atwhich the panels are supplied, as well as with the type and thickness of the metal supporting face.

A5.5 LIFTING AND HANDLINGa) LIFTINGThe packs must always be lifted by means of slings positioned at a minimum of two points separated bya distance not less than half the length of the pack itself (§7.4 of Standard UNI 10372). The slings mustbe made of synthetic fibre (nylon or high-strength polyester), at least 200 mm wide, as shown in thedrawing. We recommend using suitable spacers consisting of wooden boards or polystyrene packingabove and below the pack, to avoid direct contact between the slings and the pack.

b) HANDLINGManual moving of individual panels must be performed by at least two people, keeping the panelupright as illustrated. Suitable protective equipment must be used (gloves, safety shoes, overalls etc.) incompliance with current regulations.

Panels over a certain size (4 metres in the case of a panel of thickness 80-100 mm) must be moved bymeans of a suitable hoist or crane, as the weight of the panel makes it impossible to move by hand. Thepanel is attached to the chosen mechanical lifting gear by a lifting-beam with two or more clampsconnected to it by cables. The clamps grip the edge of the panel itself. A lifting-beam equipped withsuckers is a satisfactory alternative.Note: In the case of any eventuality not covered above, the AIPPEG Recommendations (attached) apply.

A5.6 INSTRUCTIONS FOR FITTING

A5.6.1 Preliminary information1) Check that the storage on site is in compliance with the procedures described in the AIPPEGrecommendations.2) Check that the framework corresponds to the working drawing.3) Check that the entire site labour-force is equipped with safety footwear, gloves etc, and that the sitehas all the equipment necessary to ensure safety in accordance with current regulations.

A5.6.2 Preparation of the panelsRemove the polythene protective film from the panel before fitting it.Check that the surface of the panel does not have traces of adhesive remaining from the protective film.If necessary, use a solution of detergent in water to remove it.

A5.6.3 Fitting sequences for Isopan panels – wall panels:The correct sequence for fitting Isopan wall panels is as set out below.1) Fix the base metalwork (where required) at the foot of the wall, and also the metalwork which has tobe installed before the wall, such as drips, connectors for the roofing, corner connectors etc.2) Remove the protective film from the panels, as mentioned in the preliminary information.3) Fit the panels starting from the foot of the wall, taking care to execute joints correctly and to makesure the panels are upright.4) Secure the panels only after checking that they are perfectly lined up. The fixing screws must alwaysbe inserted at right angles to the panel.5) Fit the finishing components (corner strips, perimeter edging etc.).6) Carry out a general inspection and cleaning of the wall, paying particular attention to the fixings andthe joints with the door and window frames.

A5.6.4 Fitting sequences for Isopan panels – roofing panels:1) Start at the bottom and work upwards, finishing at the ridge.2) Fit gutters, sealing caps and rainwater flashings.3) After fixing the first row of panels, working away from the direction of the prevailing winds, lay thesucceeding panels, superimposing the hollow rib on the solid rib of the panel already laid, and gentlyrotating the panel (see diagram).

A5.6.2

Manoeuvre for assembling the panels

A5.6.5 Cutting the panelsThe operation of cutting the panels comprises the following stages:1) Protect the area affected by the cut with adhesive tape.2) Use a panel to mark the required cut on the tape.3) Make the cut with a jig saw (equipped with dust extraction and filtration), following all theprecautions and safety procedures specified by current regulations.4) Remove the swarf produced by the cut because it can scratch the paintwork of the panel itself, andtherefore impair its long-term durability.5) Remove the protecting adhesive tape.

A6.1 TYPES AND INTENDED USESPanels designed for use on pitched roofs (Isofire Roof 1000) and in walls (Isofire Wall 1000).Characterised by a core of mineral fibre which guarantees the incombustibility of the product besidesensuring excellent thermal insulation. The “Fono” versions are expressly designed for sound insulation.The panels were created to satisfy the growing demand for improved performance in fire behaviour,while maintaining good mechanical characteristics.These panels have been tested at the Istituto Giordano S.p.A., obtaining the following certification:• Class 0/1 reaction to fire (in terms of Ministerial Decree 26/06/84);• Fire resistance: R.E.I. 30 / R.E.I. 60 / R.E.I. 120, depending on the thickness (in terms of Interior

Ministry Circular 91, 14/09/61);• Sound insulation to ISO 140 1995 and ISO 717 1996, and sound absorption to ISO 354 1985, for

Fono version.

A6.3 OVERLAPSThere is no gasket provided for the longitudinal overlap joint, because the mineral wool must form asingle continuous insulating layer, to guarantee the specified incombustibility and fire resistance.In the case of transverse (overlapped) joints, incombustible (Class 0) tape and gaskets must be fitted inorder to ensure a perfect seal and complete impermeability without invalidating the fire-retardantproperties of the panel. On roofing panels, the overlap must be achieved using the same procedures ason polyurethane panels, cutting away part of the insulation of the upper panel.

A6.6 R.E.I. PANELSThe ISOFIRE series of panels is specially designed for the construction of rooms where fire can safely bekindled, and conversely of rooms which are required to be protected from the attack of fire coming fromoutside sources.There is a variety of industrial uses for which ISOFIRE panels are particularly indicated, as for example:• Protection of escape routes• Fire escape stairs• Lifts• Fire barrier walls• Store rooms• Suspended ceilings• Clean rooms.In addition to the above, they can be correctly used for the creation of safe rooms or compartments inaccordance with the current regulations, particularly in terms of the “Definitions for the purposes ofAnnexe A of the Decree by the Interior Minister of 30/11/1983”, cited below:

A6.6.1 Fireproof Compartment:“Part of a building delimited by structural elements of a predetermined fire resistance, organised to fulfillthe requirements of the prevention of fires.”

A6.6.2 Smoke-proof filter:“Compartment delimited by structures with a predetermined R.E.I. fire resistance, in any event not lessthan 60 minutes, and provided with two or more doors equipped with self-closure devices with apredetermined R.E.I. fire resistance, in any event not less than 60 minutes, with a ventilation shaft ofadequate section, in any event not less than 0.10 m2, issuing above the roof of the building; orcompartment with the same fire resistance characteristics, maintained at an overpressure of at least 0.3bar, even in emergency conditions, or vented directly to the outside with unobstructed openings havingan area not less than 1 m? excluding ducts.”

A6.6.3 Smokeproof stair wells or protected stairs:“Protected staircase in well constituting a fire-resistant compartment having direct access from everyfloor with doors of R.E.I. fire resistance equipped with closing devices”. ISOFIRE panels are designed toprovide certificated high performance in fire resistance. (As provided by the current regulations, thecertification of the products, particularly for fire resistance, is effected by real furnace tests on limitedsamples of the product). These tests guarantee the R.E.I. value for the panels and their jointing(longitudinal joint) at the test dimensions.

Note: Obviously the standard trial is not carried out on the complete installation (every completedproject, however similar, has some unique and unrepeatable characteristics). In particular it cannot testthe actual situation at the junctions – panel/floor, panel/beams (of various materials), panel/ceiling andpanel/wall, or the various passageways for pipes, cables etc. It is therefore essential that the designertakes an engineering approach so that the intended performance can be guaranteed, especially as

regards impermeability to flames, vapours and gases (E), and the thermal insulation (I) of the entiresystem.In reality, these qualities are more closely connected with the procedures followed in carrying out thework and assembling the components, than with the specific and individual characteristics of thesecomponents, important though these are.

A6.6.4 Fire resistanceISOFIRE insulated panels are certified in accordance with current national standards, in recognition oftheir performance in fire resistance, which contributes to the “R.E.I.” grading of the product. Followingthe definitions given in Point 1.11 of Annexe A of the Decree by the Interior Minister of 30/11/1983,we can provide an exact explanation of the terminology used in assigning the values and the variablesdescribed in the Decree. In particular, we draw attention to the following definitions:• Fire resistance: capacity of a construction element (component or structure) to maintain, for a fixedperiod of time:–• its stability “R”, the tendency of a construction element to retain its mechanical strength under theaction of fire;• its seal “E”, the tendency of a construction element when exposed to the action of fire on one side,not to let flames, vapours or hot gases pass, or produce them on the side not so exposed;• its thermal insulation “I”, the tendency of a construction element to reduce the transmission of heat.Accordingly:

A6.5

• The symbol “R.E.I.” is used to identify a construction element which, to qualify, must maintain itsmechanical strength, its seal against flames and gas, and its thermal insulation, for a fixed period oftime.

• The symbol “RE” is used to identify a construction element which, to qualify, must maintain itsmechanical strength and its seal against flames and gas, for a fixed period of time.

• The symbol “R” is used to identify a construction element which, to qualify, must maintain itsmechanical strength for a fixed period of time.

In relation to the requirements which they have demonstrated, structural elements are classified by anumber, which represents the minutes. The time period for which the performance is guaranteed, in theclassification of elements not bearing the rating “R”, is automatically satisfied if criteria “E” and “I” aresatisfied.ISOFIRE panels have received the certification R.E.I. 30 / R.E.I. 60 / R.E.I. 120, depending on thedifferent thicknesses, when used as non-stressed partitions, as indicated in the certifications, which aredifferentiated as regards the models and as regards their uses as roofing panels (non-stressed) and asvertical dividers. In view of the large number of construction types in the panels, it is important whenusing and checking the certified performances in fire resistance, to correlate exactly the model of panelwith the certification obtained.For the detailed characteristics, always refer to the ISOPAN technical documentation. For example, the‘ROOF’ model of panel is certified both for use in roofing, and as a wall panel, but always with thespecification that the side which can be exposed to the fire is the flat side (without ribs).

The model ‘WALL’, on the other hand, can be used for possible exposure to the fire on both faces, butonly when positioned vertically in a wall. Strictly according to the standard, the certified performancesrefer to and are guaranteed only in the test conditions, which involve components of limited dimensionsassembled with the particular joint. It is the responsibility of the designer to justify in “engineering” termsthe extension of these performances to dimensions and procedures different from laboratory testconditions, particularly as regards length and therefore the scarcity of intermediate supports andbearings, and also as regards end-to-end joints, and the combination with other construction elements,especially structural members. As we have already stated, the object of this booklet is to supply thedesigner with advice and information to favour the identification of correct solutions and materials whichwill guarantee the fire resistance characteristics of the entire installation. The other components besidesthe panels, the structural elements in particular, must be able, in virtue of their composition, to resist firefor the necessary time.If this condition cannot be met, these structural elements must be treated with the usual protectivemethods (intumescent paints, insulating or intumescent plaster etc.) and checked by the designer forcompliance with the current applicable regulations, particularly Circular 91 and Standards CNVVF andUNI 9502, 9503 and 9504 etc.

A6.6.5 Outline of fire safety legislationThe use of ISOFIRE panels as elements resistant to fire is not structural, but aimed at contributing to thecreation of compartmentation, that is, a separation of zones to be protected or insulated (safe zones)from others where there exists a greater possibility of a fire starting, or, conversely, to delimit zones atgreater risk of fire.The principal aim of the panels in such applications is to retard the spread of the high temperature (and

A6.6

therefore of the fire) and of the combustion gases, for a fixed length of time, allowing people, materialsand machinery to be brought to safety, and allowing action to be taken at the fire source itself before thefire spreads out of control. The Italian fire safety regulatory situation does not seem altogether systematicand functional, nor is it wholly consistent nor aligned with the legislation in other European countries. Alarge number of regulations have been drawn up or are in process of being drawn up, some of themlaying down new procedures for homologating materials and new systems and solutions for fireprotection.

A significant part of the legislation currently in force, which can be taken into consideration in theconstruction of partitions using ISOFIRE prefabricated panels, is listed below:• Circular 91 of the Minister of the Interior of 14 September 1961;• Ministerial decree of 30 November 1983 – “Terms, definitions and graphic symbols in fire prevention”

– which, among other things, defines fire resistance and the various R.E.I. characteristics;• Directive of the Council of the European Union 89/106/EEC of 21 December 1989, relating to

harmonisation of the various national regulations.In addition, for purposes of comparison and for the treatment of the structural components to which thepanels are attached, it may be useful to refer to the Standards:• UNI EN 10143, UNI EN 10147 for Steel• EN 10088-1, EN 10088-2 for Stainless Steel• UNI EN 485-4 for Aluminium

A6.6.6 Suggestions for making connections and jointsThis manual contains suggestions relating to the commonest cases of combining ISOFIRE panels withothers of the same type and with other building components. Naturally, the solutions put forward mustbe considered merely indicative, and require checking case by case. The joints which we need toconsider are the transverse joints, since the longitudinal joint in ISOFIRE panelling is tested in the trialsfor certification, and the characteristics required are thus guaranteed.In choosing the materials for fitting the products, it is important to remember that fire resistance must beensured by the construction materials used (panels, beams, columns etc.)Those elements among them which are not certified must be protected with guaranteed, certifiedmaterials (intumescent paints, intumescent or fire-retardant plaster etc.)

A6.6.7 Principal types of operationAlthough we believe that the attached sketches are sufficiently clear and simple to be understood and forthe principles to be extended to other similar cases, we describe some significant cases in the next fewparagraphs.

a) COMPARTMENTATION:

1 – Linking a vertical wall to the floor: the R.E.I. characteristics are ensured by the conformation of thewall (certified) and of the floor (concrete slab). Thermo-expanding seals (gaskets or sponge) arerecommended, which, by expanding under the influence of the flame or the temperature, tend toensure the seal. Smoke and gases are thus prevented from getting through any narrow gaps at the

A6.7

joint, and consequently no uncontrolled rise in temperature takes place on the side not exposed to thefire.

2 – Linking a vertical wall to the ceiling: it is advisable to provide enough play to facilitate fitting and toabsorb deformation in the ceiling. In the case of a stressed slab or beam, the play provided must besufficient to absorb deflection in the stressed structure, taking its own deadweight into account. Thefire protection can be achieved by the use either of gaskets of suitable dimensions or of sponge ofappropriate thickness.

3 – Linking to elements different in type and composition from ISOFIRE panels (beams, slabs, columns inreinforced concrete, prestressed concrete, iron etc.): besides adequately protecting such elementswith specific fire-retardant products, take account of deformation which they may undergo as a resultof loading or thermal expansion. This can be achieved by providing sufficient free play and usingfire-retardant materials (seals, gaskets, felt etc.), which are thermo-expanding but sufficiently soft andelastic.

b) ITEMS CROSSING OR FITTED INTO THE PANELS:On the subject of pipes, ducts or cables passing through the ISOFIRE panels, or window-frames beingfitted into them, we list the commonest cases and the appropriate precautions to take to preserve the fireprotection characteristics of the panels:

1 – Combustible or heat-sensitive pipesWe suggest the following protection systems:• Recessed thermo-expanding collars, concentric with the pipes, set into the partition. It is importantto check the seal between partition and collar, caulking it if necessary with intumescent or fire-retardant mastic.• External thermo-expanding collars, concentric with the pipes, mounted visibly on one or both sidesof the partition: easy to fit, but aesthetically less pleasing than the preceding solution.• Intumescent tape, wrapped round the pipes and sealed with ceramic mastic or intumescent sealant.

2 – Small diameter plastic tubes carrying cablesFit collars in thin-gauge steel with a band of intumescent material of suitable thickness. Plug the cavityin which the cables run, following the procedure described below.

3 – Metal pipesSeal the gap with intumescent mastic. Alternatively, wrap the pipes with intumescent tape, and makethe final seal with intumescent or ceramic mastic or plaster.

4 – Electrical cables, single or in a compact bundleWrap with intumescent tape or fill with intumescent mastic or plaster.

5 – Open cable ductUse fire retardant thermo-expanding bags, or intumescent felt, combined with intumescent mortar orplaster, or infill with fire-resisting panels.

A6.8

6 – Cable duct with coverSeal the spaces between the cables and inside the duct with intumescent sponge or mastic, and sealthe outside of the duct where it passes through the panel with intumescent or fire-retardant mastic orplaster.

7 – Air conditioning ductsWrap the ducts (not insulated and obviously fitted with firestop dampers) with intumescent felt ortape, sealing with intumescent or fire-retardant mastic or plaster

8 – Holes passing throughLarger-sized holes passing through the partition which cannot be sealed by the methods indicatedabove, must be closed by the usual methods or with other materials, such as for example panels inmineral wool treated with an intumescent or fire-retardant product, or intumescent, fire-resistant bagsetc. Particular care should be taken if fire-resistant mortar is used, because it will have a differentcapacity for deformation from the ISOFIRE panels, with a consequent risk of cracks and fissuresopening up.

9 – Doors and window-framesWhen positioning and installing doors and window-frames in firestop partitions formed with ISOFIREpanels, follow the instructions of the manufacturer of the frames. The model chosen must obviously becertified and consistent with the grade of fire resistance designed and guaranteed for the rest of thesystem.

A7 CERTIFICATION

Isopan panels have obtained technical approval from the strictest and most reputable internationalresearch institutes in Europe, charged with issuing such certification. In particular, the ITC, the ItalianInstitute for Construction Technologies, has issued Certificates of Technical Approval for our roofing andwall panels, while UGPU, the highly authoritative German Institute, has issued Approval for the panelsproduced by our plant at Patrica in Lazio. Many other European official bodies have certified the qualityof our manufactured goods, and also the compliance of the raw materials and the finished product withthe strictest standards of the individual countries and European standards. ISOPAN submits itselfperiodically to monitoring by the inspectors of the various Institutes, who oversee our production toensure that the Approval standard is maintained.Some of the best-known Certifications are illustrated below, with the corresponding attestations.Recently the list was increased by the addition of the Certificate of Conformity to the Standard UNI ENISO 9001:2000, which bears witness to the quality achieved in the production process for plain andribbed panels at the production plant in question.The ISOPAN Technical Office will be very happy to supply the list of the certificates available, and tosend out exact copies of the original.

1. PACKAGING

Following is the unabridged text of article 7.1 of UNI 10372 Regulation (inItalics):

To maintain their durability after installation, metal roofing elements mustnot be damaged during storage, transport, handling or fitting operations. Itis recommended to provide temporary protection of the required productspecifications (aesthetic characteristics in particular).

During the manufacturing process, the above mentioned materials areusually protected by polyethylene film (adhesive or cling-film) or by othersystems.

During the following phases the Manufacturer must take precautions inorder to guarantee the following:- protection of the product surface against abrasion, especially duringhandling;- protection of corners and edges against impact and crushing;- protection against water stagnation or condensation;- protection against permanent deformation of elements bearing theweight of the whole pack or of stacked packs

Profiled sheets and panels are usually supplied in packs. The number ofsheets per pack must be such as to keep the overall pack weight withinthe limits of the hoisting and transport equipment used.

Materials used for packaging are usually as follows: wood, expandedplastic materials, cardboard, polyethylene film (heat-shrinkable orstretchable) or other materials; packs must be tied with straps (no metalwire) and suitable protection devices (edge-protectors, etc.). Straps mustnot be used as harnesses for hoisting.

It is also recommended to properly indicate the hoisting points forhandling and hoisting operations.

Product packs must always be equipped with a support system touniformly distribute weight and allow for proper handling.

Such support systems may include expanded plastic or dry wooden joists,or composite material sheets positioned at distances establishedaccording to product characteristics.

Packaging must be fully and properly specified in the purchase order onthe basis of the means to be used for transportation (cages or cases fortranshipment, rail transport or shipping). The type of packing varies withproduct characteristics.

Packaging must be carried out in compliance with Manufacturer’sparameters. Any different grouping of elements and/or special packagingmust be specified in the purchase order and acknowledged by the seller.

2. TRANSPORTATION

Following is the unabridged text of article 7.2 of UNI 10372 Regulation (inItalics):

Packs must be transported by suitable vehicles, and:- packs must be supported by expanded plastic or wooden spacers,positioned at distances established according to product characteristics;- the support surface must be compatible with the pack shape (flat for flatpacks, with a matching curve for curved packs);- packs must be stacked fitting suitable expanded plastic or woodenspacers between the packs, if not included in the packaging;- packs must not be more than 1 m. different in length, depth or height;- packs must be clearly marked with where to position hoisting harnesses,if such areas are not self-evident;- compliance with any other Manufacturer’s specification.

Packs must be placed on a flat surface and expanded plastic or woodenspacers of suitable size and number must be positioned under the packs.A perfect vertical alignment of spacers is required.

The carrier must secure packs to the vehicle using crosswise slingspositioned at a maximum distance of 3 m, provided that each pack issecured by at least two crosswise slings.

The load must always be covered during transportation and the siderunning along the vehicle must be waterproofed. The Buyer collectingproducts is responsible for instructing the drivers in this matter.

Packs must be loaded on a completely free and clean platform. Vehiclespartially loaded with other materials or with unsuitable loading platformsare not acceptable.

Products must be loaded on vehicles according to carrier instructions. Thecarrier is fully liable for damage to the load and shall take all thenecessary precautions to prevent damage due to the weight on thebottom pack or pressure at tying points, and shall prevent productdeformation caused by slings. Special loading conditions will only beaccepted upon written request by the Buyer, who shall be fully liable insuch cases.

3. STORAGE

Following is the unabridged text of article 7.3 of UNI 10372 Regulation (inItalics):

The shape of elements is designed to allow stacking, in order to minimizethe pack volume during storage and transportation; it is nonethelessnecessary to make sure that stacking does not damage product surfacesin any way.

Packs must always be stored lifted from the ground, both in thewarehouse and in the yard: they must be positioned on supports,preferably made of expanded plastic or wood, with flat surfaces longerthan the slabs and positioned at suitable distances according to productcharacteristics.

The support surface must be compatible with pack shape: flat for flatpacks, with a matching curve for curved packs.

Packs must be stored in dry places to prevent water stagnation andcondensation on the internal elements, which are less exposed to the air.Such phenomena are particularly dangerous for metals, and may causeoxidation (ex. white rust on zinc).

Packs must be stored in a suitable way to facilitate water run off,especially if they are to be temporarily stored outdoors (see figure).

If stored products are not collected for installation within a short period oftime, they should be covered with tarpaulin.

Take the necessary precautions against electrochemical corrosion due tocontact between different metals during storage.

It is preferable not to stack packs; when the stacking of lightweight packsis possible, always fit expanded plastic or wooden spacers betweenpacks. Spacers must be of the largest size applicable and in sufficientnumber, and must always be positioned vertically, on lower pack supports(see figure….).

B2.2

The best storage locations are closed spaces with some ventilation, freeof dust and humidity.

In all cases, and especially for yard storage, a steady support surfaceshould prevent water stagnation.

Packs must not be positioned near processing areas (such as metalcutting, sandblasting, painting, welding, etc.), or where vehicles pass by orstop (impact, splashing, fumes, etc.)

Do not stack more than three packs, or over a maximum overall height ofapproximately 2.6 m. Suitable supports are required for stacking.

If materials are wrapped in protective film, make sure the film iscompletely removed during installation, and in any case within threemonths of materials becoming usable. Carry out any other specificinstructions of the Manufacturer.

On the basis of experience and subject to compliance with currentregulations, it is recommended not to exceed twelve months ofuninterrupted storage in closed spaces, in order to maintain originalproduct characteristics. Outdoor storage should not exceed three months.Materials must be protected from direct sunlight at all times, since it maycause product alteration.

If tarpaulin is used, make sure it is waterproof and properly ventilated toprevent condensation and water stagnation.

4. HOISTING AND HANDLING

Following is the unabridged text of article 7.4 of UNI 10372 Regulation (inItalics):

Packs must always be lifted by means of slings positioned at a minimumof two points separated by a distance not less than half the length of thepack itself.

The slings used for hoisting must preferably be made of synthetic fibre(nylon), at least 10 cm wide, positioned in order to take the weight evenlyand correctly and to prevent deformation (see figure).

It is recommended to use suitable spacers consisting of heavy-dutywooden or plastic boards positioned above and below the pack, to avoiddirect contact between the slings and the pack.

Such spacers must be at least 4 cm longer than the pack and at least aswide as that of the sling. In all cases, lower spacers must be sufficientlywide to prevent deformation of the lower elements due to pack weight.

Make sure that harnesses and supports cannot move during hoisting andthat all operations are carried out with caution and gradually.

Packs must be laid down only on roof frameworks with suitable surface, interms of strength, support and safety conditions. Always take otherongoing operations into account. Before hoisting a pack, authorizationfrom the Work Management should be sought at all times.

Handling must always be carried out wearing suitable protectiveequipment (gloves, safety shoes, overalls etc.) in compliance with currentregulations.

Individual panels must be moved by hoisting the element without draggingit over the lower panel and rotating it upright alongside the pack; transportmust be carried out by at least two people according to panel length,keeping the panel upright as illustrated.

Hoisting equipment and gloves must be clean and able to preventdamage.

The use of fork-lifts is not recommended, as such equipment may damagethe packs.

Packs laid down at roof level must always be properly secured to theframework.

1. INTRODUCTION

The following Recommendations provide reference information for theinstallation of corrugated sheets and insulated metal panels. They arecomplementary to UNI 10372 Regulation “Discontinuous cover panels –Instructions for the design and production of metal sheets”.

Each project shall take into account the needs of individual building yards,which shall be equipped with suitable handling and installation tools, incompliance with current safety and accident prevention regulations.

The company responsible for installing the corrugated sheets/panels shallnot only be fully conversant with the characteristics of the materials in use,but also have qualified personnel suitable for yard operations, to ensurethat the installation is carried out in compliance with project specifications.

The Seller shall not be liable in cases in which the followingRecommendations are disregarded or yard operations are carried outimproperly.

An efficient, well-organized and properly coordinated yard is the bestguarantees of overall installation productivity.

2. CONSTRUCTION ELEMENTS

Corrugated sheets/panels are used in civil and industrial constructionapplications in order to build roofs, walls and floors; they can be fitted toall kinds of support framework: metalwork, normal and prestressedreinforced concrete, and wood.

Support frameworks and fixing elements of corrugated sheets/panels shallbe of suitable size and shall comply with project conditions in terms ofsafety, stability and functioning.

Corrugated sheets and insulated metal panels are quick and easy toinstall, covering the entire pitch length, or wall height, or several floorspans, with a single element. The length of metal elements essentiallydepends on transportation and handling requirements, on the materialused and on production technology.

Support surfaces shall be suitable for use with corrugated sheets andinsulated metal panes and related fixing methods.

Most frequent conditions:

1. ROOFING1.1 corrugated sheet1.1.1 single corrugated sheet1.1.2 sandwich carried out during installation1.1.3 deck carried out during installation

1.2 monolithic insulated panels1.2.1 prefabricated monolithic sandwich1.2.2 pre-insulated deck

2. WALLS2.1 corrugated sheet2.1.1 single corrugated sheet

2.1.2 sandwich carried out during installation2.2 monolithic insulated panels2.2.1 prefabricated monolithic sandwich

3. FLOORS3.1 single sheet3.2 sheet with supporting concrete3.3 corrugated sheet as disposable formwork

The fitting sequences of roofs, walls and floors differ.

3. PRELIMINARY OPERATIONS

Before starting operations in the yard, the operator shall:

1. Examine project drawings and comply with the instructions;

2. Make sure that support frameworks for corrugated sheets/panels arecorrectly aligned;

3. Make sure that the support framework surfaces which will come intocontact with the corrugated sheets/panels are compatible with oneanother or otherwise protected from electrochemical corrosion;

4. Make sure that overhead electric cables or other materials do notinterfere with the corrugated sheets/panels;

5. Make sure that operations at ground and roof level are compatible withyard activities;

6. Make sure that the building yard is suitable for material storage andhandling, in order to prevent damage to sheets/panels.

The operator shall carry out all operations in compliance with currentsafety regulations. Hoisting, handling and storage of corrugatedsheets/panels at roof level shall be carried as set out in Enclosure A,section 4.

The sole of boots worn by personnel responsible for installation shall notdamage the outer facing of sheets/panels. For all cutting operations in theyard, always use suitable tools (reciprocating saw, shears). The use ofabrasive disc tools is not recommended.

For fixing operations we recommend the use of a screwdriver with torquelimiter.

To prevent condensation, elements (roofing panels in particular) shall becorrectly overlaid.

4. ROOFING

SLOPE

The roof slope depends on environmental conditions, the design and typeof rook.

For roofing with pitch elements without end-to-end joints (pitch-lengthsheets), the slope is generally no less than 7%. For flatter roofs, follow theSupplier’s instructions.

In the event of overlap at the head of panels, the slope is determined on thebasis of the type of joint, the materials used and environmental conditions.

For deck roofing, the slope may be reduced to the minimum allowingwater to run off correctly.

FITTING SEQUENCE

The correct sequence for fitting roof panels is as set out below.

8. Fit the outside sheet in compliance with section B.1), steps 2 to 5.

9. Fit the finishing components (corner strips, perimeter edging,connectors for roofing and walls, etc.).

10. Carry out a general inspection and cleaning of the wall, payingparticular attention to the fixings and the joints with the door and windowframes.

B.2) Crossed corrugated sheet sandwich

1. Remove the protective film from the wall panels, where required.

2. Fit the panels starting from the foot of the wall, taking care to makejoints correctly and to make sure the panels are upright.

3. Secure the panels after checking that they are perfectly lined up.

4. Fit flashing elements for the first sheet (joints, special elements).

5. Fit rigid spacers of suitable size, positioned as shown in the drawings. Ifmetal spacers are used, it is recommended to make a heat break betweenthe spacers and the outside corrugated sheet. If the inside sheet is madeof staves, rigid spacers are not required, but a heat break isrecommended.

6. Fix the base metalwork (where required) at the foot of the wall.

7. Fit the insulating material (making sure that heat insulation is uniform),any special layers (as steam barrier, separating layer, etc., in compliancewith the requirements of each building). This operation shall be carried outduring fitting of the external sheet.

8. Fit the outside sheet in compliance with section B.1), steps 2 to 5.

9. Fit the finishing components (corner strips, perimeter edging,connectors for roofing and walls, etc.).

10. Carry out a general inspection and cleaning of the wall, payingparticular attention to the fixings and the joints with the door and windowframes. For horizontally positioned corrugated sheets/panels, consultproject instructions.

6. FLOORS

FITTING SEQUENCES

The correct sequence for fitting wall panels is as set out below.

A) Single sheet (type 3.1)

1. Fix the perimeter edging, where applicable.

2. Remove the protective film from the floor panels, where required.

3. Fit the sheets making sure that they are correctly juxtaposed andoverlapped. Check that the sheets are perfectly lined up andperpendicular to the underlying framework.

4. Secure the sheets in compliance with project instructions, afterchecking that they are perfectly lined up, then join the sheets alonglengthwise overlaps. All waste material, especially metal scrapings, shallbe immediately removed.

5. Complete the floor in compliance with project instructions, payingattention not to load the floor panels with concentrated loads.

B) Sheet with supporting concrete (type 3.2)

1. Fit concrete containing elements.

2. Fit the sheets making sure that they are correctly juxtaposed andoverlapped. Check that the sheets are perfectly lined up andperpendicular to the underlying framework.

3. Secure the sheets in compliance with project instructions, afterchecking that they are perfectly lined up, then join the sheets alonglengthwise overlaps. It is necessary to make sure that corrugated sheetsare free from oxide and oil stains, or any other substance that mayprevent adhesion to the concrete. All waste material, especially metalscrapings, shall be immediately removed.

4. Use sealing adhesive tape to prevent concrete from dripping at thehead junctions of corrugated sheets.

5. Position the electrically welded wire mesh and/or framework bars at thesupports in compliance with project instructions.

6. Cast the concrete paying attention to avoid accumulation, especially inthe centre of the floor span.

7. If the project design requires the use of props, put them in place beforeconcrete casting, providing corrugated sheets with the required countertracing.

C) Corrugated sheet as disposable formwork (type 3.3)

1. Fit concrete containing elements.

Follow the instructions set out at section B), except for step 5, whereframework bars are required.

7. FASTENERS

Fasteners are essential components of the roofing, siding and flooringsystem. It is thus necessary to use the fasteners recommended by theManufacturer of corrugated sheets/panels.

Instructions for a correct installation:

Roofs:

- external facing (type 1.1.1, 1.1.2 and 1.2.1): a whole kit, usually includingscrews, caps and sealing gaskets, to be fitted to the corrugation ridge.- internal facing (type 1.1.2, 1.1.3 and 1.2.2): screw and gasket (whererequired).

Walls:

- external facing (type 2.1.1, 2.1.2 and 2.2.1): screw and gasket.- internal facing (type 2.1.2): screw and gasket (where required).- prefabricated monolithic panels with “hidden” fixing: specific fixing kit

Floors: screws, nails, washers to be welded during installation.

The density and position of fixings required varies with the characteristicsof the construction elements, the type and size of support, and localclimate situation (wind in particular). In any case, always consult projectinstructions.

In most cases, corrugated sheets/panels are fixed with screws of differenttype, in compliance with the support framework.

1. Fixing to metal framework:

- self-tapping and self-threading screws (depending on support thickness)- thread-forming screws - fired in nails (for floors and inside sheets of sandwich carried out duringinstallation)- threaded hooks with nut (usually for fixing to tube elements)

2. Fixing to wood framework:

- wood screws- threaded hooks

3. Fixing to reinforced concrete and prestressed reinforced concrete:

This fixing method applies to steel or wood support elements incompliance with the types set out at point 1 and 2.

Direct fixing to reinforced concrete and prestressed reinforced concrete isnot recommended.

For deck roofing and floors, ribbed fixings are required, usually with rivetsfitted along the longitudinal overlap, at a maximum distance of 1000 mm.

For other roofing and siding elements, ribbed fixing is also recommended,in compliance with the type of overlap.

8. FINISHING COMPONENTS

Finishing components are an integral part of the whole installation, andplay an important role in guaranteeing the performance characteristics ofa project.

The Manufacturer of corrugated sheets/panels is usually able to providefinishing components as well, which shall be fitted in compliance withproject and/or supply instructions.

The Buyer shall define the range of finishing components required incompliance with its needs. The Manufacturer of corrugated sheets/panelsis responsible for the compliance of materials with the order confirmationonly for directly supplied and properly installed components.

The finishing components include gaskets of different shapes, flashing(ridges, under-ridges, gutters, drains and rainwater downpipes, lighningconductors, drips, corner connectors, etc.), translucent slabs, cups,ventilators, door and window frames and secondary components.
