ISOCOP Metal faced insulating panel

DESCRIPTION

A roof panel that is very versatile and gives high aesthetic results. The different options allow the choice of a customised product in order to meet the clients expectations. Aesthetically pleasing, it allows the integration of different roof systems thanks to a wide range of elements of flashings and roof windows. It is also appropriate for mono and polycrystalline photovoltaic roofs.

GEOMETRICAL CHARACTERISTICS

Length: up to the maximum transportable length; to be defined according to the restrictions of use.

Utile pitch: 1,000 mm Thickness: 30, 40, 50, 60, 80, 100, 120 mm Internal face: lightly profiled sheet External face: profiled sheet, with 40mm high ribs, pitch to be defined according to

the number of ribs.

- ISOCOP-5 roof panel, with external profiled sheet characterised by 5 ribs every 250 mm -

METAL FACINGS

Hot dip galvanised steel by means of a SENDZIMIR continuous process (EN 10346) and pre-painted by means of a coil coating continuous process with cycles of polyester resins, high durability polyester (HDP), PVDF (polyvinylidene fluoride), on the visible side; a primer is applied on the sheet internal side.

AISI 304 Stainless steel (designation X5CrNi1810) according to the EN 10088-1 standard.

3000 or 5000 series Aluminium alloy with a pre-painted finish, with the cycles of the previous point, with a natural or embossed effect.

In case of aluminium facings, these should preferably be applied on both sides: in fact, if different materials are used on the two sides, this may cause the panel to distort and bend due to the different thermal expansion coefficients of the sheets.

For copper facings that are 6,000 mm long minimum, it is necessary to create a slot on the fixing hole, due to the high value of thermal expansion coefficient.

For stainless steel facings, when the aesthetic factor is particularly important to the building, it is necessary to take account of possible appearance of unwanted waviness emphasized by these reflective surfaces.

PROTECTION OF THE PREPAINTED METAL FACINGS

All the metal prepainted metal facings are supplied, on request, with a protection film in adhesive polyethylene that helps prevent damages to the layer of paint. If the material is specifically requested without the protection film, Isopan S.p.A assumes no liability in case of damages to the layer of paint. The protection film that covers the prepainted metal facings must be completely removed during the assembly phase and in all cases within three months after the material production. It is also recommended not exposing the panels covered by a protection film to the direct sunlight.

INSULATION Made with rigid polyurethane foam, with an appropriate degree of fire resistance in accordance with the current European standards. Composition of the polyurethane resin formulation (PUR or PIR on request) Average density 40 kg/m3 10% Compressive strength 0,11 MPa (at 10% deformation) Tensile strength 0,1 MPa Shear strength 0,1 MPa Thermal-conductivity coefficient = 0.022 W/mK The 95 % closed cells polyurethane foam guarantee an anhygroscopic structure.

LOAD BEARING CAPACITIES

ISOCOP is a self-supporting panel according to the UNI EN 14509 definition: ... panel capable of supporting, by virtue of its materials and shape, its self-weight and in the case of panels fixed to spaced structural supports, all applied loads (e.g. snow, wind, internal air pressure), and transmitting these loadings to the supports. The type of metal facings, their thickness, and the thickness of thermal insulating core, determine the bearing capacity of the panel, as shown in the tables of the ISOCOP catalogue. The resistance value is referred to a panel horizontally assembled and subject to the action of a distributed load; the calculation method used by Isopan does not take into account the thermal effects, which are verified by the designer. However, the creep effect for the insulating core, due to accidental overloads, is taken into account. Depending on the weather conditions of the installation location and the colour of the external face, if the designer feels that a detailed verification of the stresses caused by thermal actions and long-term effects is necessary, he/she should contact the Isopans Technical Office. The designer is responsible for the check of the fixing systems, based on their number and the way they are placed.

JOINT The joint is equipped with a sealant gasket inserted during production phase. The overlap shape is expressly studied to prevent infiltrations and to reduce thermal bridges. For special end-use requirements, in order to avoid condensation on the metallic surface, an optional gasket should be placed on site to increase the airtightness of the joint; this element can be provided by Isopan and will be installed on site during the assembly phase.

ISOCOP panels reaction to fire has been tested according to EN 13501-1 and to test methods defined in EN ISO 11925-2 (Reaction to fire test for building products - Part 2 - ignition when subject to the direct contact with the flame) and EN 13823 (Reaction to fire test for building products - building products excluding floorings exposed to a thermal attack of a single element in combustion). To obtain more information, please contact the Isopans Technical Office.

BROOF ISOCOP panel is marked CE according to EN 14509: 2007 Self-supporting double skin metal faced insulating panels Factory made products Specifications, force from 1 October 2010, in compliance with the 89/106 CEE regulation of construction products. ISOCOP panel with PUR2 or PIR foam, according to Annex C.3 Fire Test ENV 1187 external fire performance for roofs included into the UNI EN 14509, has been approved for classification without further testing (CWFT): ISOCOP panel satisfies external fire performances. ISOCOP panel with PUR2 or PIR foam is classified BROOF, according to UNI EN 13501-5 and to the European Commission decision 2006/600/EC.

WATER PERMEABILITY

The resistance to driving rain under pulsating air pressure of a sandwich panels assembly must be tested according to the EN 12865 standard. The panel has been classified as Class B: normal applications.

RESTRICTIONS OF USE

A thermohygrometric check should be performed during the design phase. In certain conditions (for example, high indoor humidity level) condensation can appear on the internal face of the panel with consequent drooling inside the construction; if such conditions occur long enough, they can accelerate the natural oxidation of the sheet.

If an aluminium sheet is used as external face, it is necessary to take the different thermal expansion coefficients into account, during the design phase.

Due to solar radiation, the panel external face can reach relatively high temperatures. In some cases, for example, with dark colours it can reach a temperature of 80 / 90C . This temperature would be able to bend the panel and wrinkle the sheet. With an accurate design, which takes into account the environmental conditions, the


length, the colour of the panels, the sheet thickness and the quantity of fixing elements, the possible problem occurrence may be limited. (see the thermal expansion section)

GENERAL DESIGN INSTRUCTIONS

The roof panels generally require, during the design phase, a structure able to absorb the external loading stress, that will not submit the metal face of the panels to excessive and permanent distortions to the detriment of their basic characteristics. During the design phase, in order to chose the panel types, you should consider some parameters related to the environment actions :

Wind action: it depends on the climatic zone of the building installation; the values fluctuate depending on the wind speed with a consequence of more/less load pressure on the exposed surfaces (impacts on the type and number of fixing elements);

Snow load: it depends on the elevation of the site above the sea level compared with the height in situ of the building. Account must be taken of water puddles resulting from snowmelt which can expose the overlapping joints to be pressed under a load of water and possibly create infiltrations. It is a good thing, therefore, to adopt constructive measures (by adopting appropriate flashings), in order to always ensure normal water run-off.

Thermal stress: largely depends on the colour of the panel external surface and on the exposure of the construction, and can create important deformations of the system;

Atmospheric corrosion: depends on the context where the panels are installed (marine, industrial, urban, rural) and principally impacts on the degree of corrosivity of the panels surfaces. With regard to this, facings (metallic or organic) that are appropriate to the type of context in question should be chosen (we recommend to consult the available documentation or to contact the Isopans Technical Office).

Rainfall: it affects the slope angle of the roof; in order to ensure normal water run-off and to prevent oxidation of the metallic supports, the slope angle of the panels must be chosen on the basis of two types of construction:

Roof without intermediate overlapping joints; Roof with intermediate overlapping joints.

Low Medium High Slope (%)

In the first case, the minimum recommended slope (in case of low, medium snow cover), depending on the climatic zone and on the height of the rib, is generally not less than 7%, as calculated with the slope diagram.


In the case of roofs with intermediate overlapping joints, the percentage of slope is also calculated with the slope diagram (for percentage of slope smaller than 25%), with addition of a value equal to 0.2*L, where L is the length of the pitch (in meters). The presence of intermediate overlapping joints depends on the slope, the snow load and the wind action. Under normal weather conditions, the overlap values are generally:

Slope (%) Overlap (mm) 7 < P 10 250 10 < P 15 200

P > 15 150

Where possible, considering the UNI 10372 standard, Isopan recommends asking for the projection of the eaves to be arranged in order to create a drip and prevent possible infiltrations into the insulating core or within the building. After completing the installation of the panels and the flashings, you must ensure that the coating elements are free of foreign elements or installation debris, as they can trigger corrosion phenomena, impede natural water run-off or produce an accumulation of unwanted substances.

In order to make up for any lack of material due to damages during handling and assembly phases, Isopan recommends the supply of stock panels (quantity equal to approximately 5% of total).

THERMAL EXPANSION (UNI 10372)

All materials used for the construction of roofs, especially the metals, are subject to thermal expansion and contraction resulting from the effect of temperature change. The stresses triggered by the sheets thermal expansions operate on the roof and can cause structural and functional product anomalies , particularly in the case of

panel longer than 5,000 mm; high solar radiation; dark colours; high panel thicknesses.

As a consequence, bending and shear stress may affect the head of the fixing system These are important in the parallel direction to the ribs as in the transversal direction they are cancelled by the elasticity of the sheet profile.

-temperature range (UNI 10372)-

For high values of surface temperature, the linear extension of the metal face must not be blocked by the system; if this occurs, some stresses will appear where the profile section


changes because of the shape variation. In addition, cyclic changes of temperature associated with the day-night excursions or freeze-thaw create cyclic stresses that are not controllable and then can cause the fatigue of the support elements. These stresses can exceed the yield point of the material (creation of bubbles) or the failure limit. The effect of such a phenomenon is the fatigue crack, initially subtle and invisible, but which then generate cracking on the support reducing the structural characteristics and the watertightness. You can remedy that problem by:

using sliding expansion joints using sliding fixing elements; non using dark colours for long panels segmenting the panels using adapted type of fixing elements

In case of installing panels with aluminium or copper facings, we recommend the use of screws in stainless steel with capping and special washer against electrolytic corrosion. The fixing elements must be placed exclusively on the top of the ribs. We recommend starting with the fixing at the central purlin; the fixing at the other purlins must be modified to form a slot to allow the expansion of the panel caused by the thermal excursions. The longer is the distance from the central purlin, the longer should be the slot; with a distance of 6 meters, the slot should be 20 mm long. If the pitch length requires the use of more panels, proceed as above, starting from the panel placed immediately below. The heads of the panels must be distant of more or less 5-20 mm (minimum distance during the hottest season and maximum distance during the coldest), by taking care of inserting flexible baskets between the heads to avoid condensation. For the panels with copper external faces, particularly, the maximum recommended length is 6 meter per single panel. For anything not expressly stated, you should refer to the UNI 10372 standard and to the AIPPEG norms.

FIXING INSTRUCTIONS

The purpose of the fixings is to efficiently anchor the panel to the supporting structure; the type of the fixing group depends on the type of the supports. The number and the installation of the fixings must guarantee the resistance to the stresses induced by dynamic loads that can also exist in depression. The performance of the fixing elements is linked to the panels durability and must guarantee the adequate efficiency to the entire structure over time. Carbon steel appropriately coated or stainless steel as austenitic (AISI 304 and 316) must be chosen as material apt for fixing roofs and walls. The exposed fixing elements, those that penetrate the protective coating , must be sealed in the penetration hole to ensure the durability of the roof system; sealing rings must be used . You should particularly pay attention to the compatibility of the steel and aluminium elements, in order to prevent the formation of galvanic current.

FIXING METHODS

The fixing system depends on the project and on the installation of the panels on site; for a proper choice please contact Isopans Technical Department.

A Incorrect tightening due to a high torque applied to the screw with marked deformation of the sheet. In this situation, optimal sealing of the joint is no longer guaranteed and aesthetic appearance of the product is compromised.


B Incorrect tightening due to a torque applied to the screw insufficient to guarantee the fixing of the panel to the structure.

C Correct tightening due to a torque applied to the screw sufficient to guarantee the fixing of the panel to the structure.

Length of the screw

The proper length of the screw depends on the panel thickness and on the type of support (steel, timber); the use of cappings is mandatory for the installation of roof panels.

FIXING OF ROOF PANELS

The panels are installed with a laying direction opposite to prevailing winds, by frequently monitoring their parallelism and alignment. The holes must have a smaller diameter than the fixing elements, that must not be fully tightened, to allow expansions of the panels induced by the hygrometric conditions. The number of fixing elements depends on the climatic zone. The normal fixing pattern is like this: one fixing on alternate ribs on central beams and one on each rib on terminal beams.

ASSEMBLY INSTRUCTIONS

The operations for a correct assembly sequence are :

PRELIMINARY OPERATIONS

Verify that the supports are properly aligned Particularly pay attention to the contact points between the structures and the sheets

of the panels, in order to avoid phenomena linked to electrochemical corrosion, if non compatible metals are coupled. For this purpose, strips in elastomeric or expanded resin can be inserted as separator.

Ensure that the site area has appropriate storage and handling capacity in order to prevent material damage.

Use, for cutting operations on site, adapted equipments (toothed circular saw, jigsaw, shears, nibbler). The use of equipments that produce metallic sparks (for example abrasive discs, flex) is absolutely not recommended.

Use appropriate handling systems, particularly for long and heavy panels, in order to prevent safety risks on site and damages to the product.

Using acetic silicones is prohibited as they tend to attack the pre-painted galvanised sheet and to form incipient oxidation. It is best to use fireproof monocomponent sealant silicones with neutral curing which tend to harden due to humidity and as they are free of solvents, they do not attack the paint.


COMPOSITION OF THE PACKAGES

The panels are generally supplied packaged and wrapped with extensible polyethylene film; the standard composition of the packages is the following:

Panel thickness (mm) 30 40 50 60 80 100 120 number of panels per package 14 12 10 8 6 6 4

The compositions of package other than the standard must be explicitly requested when ordering.

ASSEMBLY

Install eavestrough, eventual subridges and connection flashings; Remove the protection film form the panels, where it is necessary. Install the roof panels starting from the eave and the side of the building, while

properly overlapping and aligning the elements and verifying the perfect orthogonality to the structure.

Systematically fix the elements after verification of their proper juxtaposition. Remove all scraps, especially the metallic ones.

Place the successive lines of elements that overlap the eaves (in case of pitch with two o more elements) Remove the insulating core in the overlapping zone.

Secure the fixing element on all ribs on the ridge line, eaves, valleys and head overlaps.

Place the finishing elements (ridges, flashings and tinsmithery) and eventual related insulating elements.

Control and clean the walls, with particular care for metallic off-cuts, fixings and fittings with the doors and windows frames.

TRANSPORT AND STORAGE

TRUCKS LOADING

The panels packages are loaded on trucks, usually two along the width and three along the height. The packages include polystyrene spacers at the base that are thick enough to allow for the lift straps.

The packages are loaded so as to ensure transport safety, in accordance with the requirements of the transporter who is solely responsible for load integrity. You should particularly pay attention to the fact that the weight imposed on the bottom package and the pressure exercised on the binding and the straps, may distort the shape of the product.

Isopan assumes no liability for loading trucks that are already partially loaded with other materials or do not have an appropriate load plan.

The client who will pick up the material must teach the drivers about it.

TRUCKS UNLOADING WITH CRANE

Type of crane equipped with lifting beams and straps should be used. Isopan can help its clients choose appropriate lifting beams and straps. By using the correct lifting systems, the panels will not be damaged.

Never use chains or metallic cables for lifting under any circumstances. Generally, the packages should be strapped leaving approximately 1/4 of the package length from each extremity.

TRUCKS UNLOADING WITH FORKLIFTS

If the trucks are unloaded with a forklift, the packages length and their possible flexion should be taken into account in order to prevent damages to the bottom of the package.

The three forks must be wide and long enough in order not to damage the product. When possible, a protection material against abrasion and surfaces scratches should be applied between the fork and the package.

STORAGE (see annex A)

The materials must be stored in ventilated indoor facilities that are free of dust and


humidity and not subject to temperature changes. The humidity that can penetrate (rain) or be formed (condensation) between two

panels can damage the coatings as it can be very aggressive to metals with the consequent oxidation.

The prepainted coatings can be more exposed to the negative consequences generated by the combined conditions of heat and humidity.

OUTDOOR STORAGE (see annex A)

If the packages and accessories are stored outdoor, the surface must absolutely be inclined in the longitudinal direction to prevent stagnant humidity and allow water run-off and natural air circulation.

If the storage is not followed shortly by the withdrawal for installation, you should cover the packages with protective tarps, while ensuring the waterproofness and the adequate ventilation to prevent stagnant condensation and the formation of puddles of water.

STORAGE TERMS (see annex A)

Learned form experience, in order to maintain the product original performance, continuous indoor storage in closed and ventilated facilities should not exceed six months, while outdoor storage should never exceed sixty days after the production date; these terms refer to the product properly stored, as indicated in the "storage" section of the annex A. The materials, however, must always be protected from direct sunlight, as it cause product alterations.

In case of transport in containers, the products must be removed from the containers as soon as possible and no later than 15 days from the loading date in order to avoid deterioration of the metal facings and organic coatings (such as blistering). Humidity inside the container must absolutely be avoided. Isopan can, at the clients request, provide special packages that are more suitable for transport in containers.

DURABILITY The product durability depends on the intrinsic characteristics of the panel used in relation with its final use. The choice of the panel, including the characteristics of the metal faces, must be done after a proper design of the roof, as indicated in the "GENERAL DESIGN INSTRUCTIONS section. With regard to this, we recommend, if necessary, making use of the Isopans documentation, also available on the web (www.isopan.it), and/or of the reference standards, such as the ECCS document "Preliminary European Recommendations for Sandwich Panels. We recommend, particularly for roof panels with prepainted galvanised facings, verifying the slope and other construction elements in order to facilitate normal water run-off and avoid stagnant aggressive materials that could create early oxidation. In the case of pitches with longitudinal overlaps, we recommend assembling the panels while paying particular attention to the sheet sealing, in order to avoid infiltrations o stagnant water on the terminal part of the panel. We recommend the use of Isopans accessories as, ridge flashings, cappings, gaskets as they are specially studied for the specific use of its products.

MAINTENANCE All types of roofs, including those made with metal face insulating panels, require maintenance activities. The typology and the frequency of such maintenance activities depend on type of metal facing (steel, aluminium); in all cases, we recommend periodically inspecting the building (at least once a year), in order to monitor the state of repair. In order to maintain the aesthetic and physical properties of the elements and to prolong the protective coating efficiency, it is also recommended cleaning regularly the roof with particular attention to areas that could facilitate the formation of stagnant rain water, where substances that are harmful to the durability of the metallic support may be concentrated.

If you notice any problems following an inspection on site, you must react immediately in order to restore the initial general conditions (for example: restoration of the paint to match local abrasions or scratches)


Technical datas and characteristics are not binding. ISOPAN is allowed to change anything without notice, the more updated documentation is available on our Internet site www.Isopan.it. For anything that is not explicitly specified, please consult the general sales conditions for profiled sheets, metal insulating panels and accessories written by the AIPPEG (Italian Association of panel and corrugated sheets producers). According to the 89/106/CE regulation, to the DPR 246 dated 21st April 1993, DPR 499 dated 12th October 1997, the panel is marked as required by the EN 14509 standard.

Isopan can, at clients request, provide useful information in order to solve specific problems related to this topic.

SAFETY The sandwich panel does not require any labels under the 68/548/CEE regulation; to meet the clients requirements, ISOPAN S.p.A redacted a document technical details for safety and recommends you to read it for any kind of information related to safety.


Annex A

TRUCKS UNLOADING WITH CRANE

For the lifting, the packages must be attached in at least two distant points with no less than half of the length of the packages themselves.

The lifting straps should be possibly made of synthetic fibre (nylon) of 100 mm of width minimum so that the load is distributed on the strap and does not cause distortion. (see figure 1)

Figure 1

We recommend the use of adequate spacers to be placed under and above the package, made of robust wooden or plastic elements to avoid direct contact of the strap with the package. These spacers must be at least 4 cm longer than the width of the package and wide at least as the strap. It is important to pay attention to straps and supports in order to avoid their movement during the lifting and to ensure the safety during the handling.

TRUCKS UNLOADING WITH FORKLIFTS

If the trucks are unloaded with a forklift, you must take into account the packages length and of their possible flexion in order to prevent damages to the bottom of the package and/or to the extreme failure limit of the panels. We recommend using forklifts that are adequate to the handling of panels of similar products.

STORAGE

The packages must always be kept off the ground in the warehouse and on construction site : must have supports made of plastic expanded material with flat surfaces longer than the width of the panel and with a distance adequate to the product characteristics. The packages should be preferably stored in dry facilities otherwise it should appear on the internal unventilated components, stagnant condensation water, particularly aggressive to metals, resulting in the formation of oxidation. The panels must be stored in dry and ventilated facilities, if this should not be possible, you should open the packages and ventilate the panel (keeping them apart from each other); if the panels remain packed outside, this can oxidise the galvanised coating (white rust) also after few days due to electrolytic corrosion. The packages must be stored to facilitate water run-off , especially when it is necessary to temporary store them outside (see figure 2) If the storage is not followed shortly by the withdrawal for installation, you should cover the packages with protective tarps. To ensure the original performance of the product, the continuous indoor storage in ventilated facilities should not exceed six months, while the outdoor storage should never exceed sixty days. The packages stored in height should always be properly bound to the structure.

PREPAINTED FACES

Figure 2 In case of prolonged storage, the pre-painted products must be stored indoor or under a canopy, there is the danger that stagnant humidity attacks the paint layer, and causes its detachment from the galvanised support. It is not recommended letting

the products stored on site more than two weeks.

In case of transport in containers, the products must be removed from the container within 15 days from the loading date, in order to avoid deterioration of the metallic supports.


PANELS HANDLING

The handling must be done by using appropriate protective equipments (gloves, safety shoes, coveralls, etc), in conformity with the applicable standard. The manual handling of the single element must always be done by elevating the element without slithering it on the lower one and turning it sideways beside the panel. The transport must be made by at least two persons, depending on the panel length, by holding the element on its side. (see figure 3)

Figure 3

Handling equipments as gloves should be cleaned to not cause damage to the panels.

INSTALLATION

The staff in charge of the panels installation must be qualified and must know the proper technique to carry out the job in a workmanlike manner. Isopan can, at clients request, provide appropriate consulting and teaching. The staff in charge of the installation must wear shoes with soles that do not cause damage to the external surface of the panel.

For cutting operations on site, adapted equipments (toothed circular saw, jigsaw, shears, nibbler, etc) must be used. It is absolutely not recommended using equipments with abrasive discs. For the fixing of the panels, we recommend the use of equipments that can be provided by ISOPAN. To tighten the screws you should use a screwdriver with torque limitation.

For the roofs with pitch elements without overlap, the recommended slope is generally 7% minimum. For the less than 7% slope, please follow the Isopans recommendations. In case of head overlapping, the slope must take into account the type of joint and material used, as well as the specific environmental conditions.

During the assembly phase and particularly during the installation of roofs, it is necessary to remove all scraps, paying particular attention to the metallic ones that, due to their oxidation, can damage the metal faces.

PROTECTION FILM

The metallic prepainted coatings are supplied, on request, with a protection film in adhesive polyethylene that helps prevent damages to the layer of paint.

The protection film that covers the prepainted panels must be completely removed during the assembly phase and in all cases within 60 days after the material preparation. It is also recommended not exposing the panels covered by a protective film to the direct sunlight.

For panels expressly required without protection film it is necessary to take special care during handling and installation on site.

MAINTENANCE

The principal activity of ordinary maintenance consists in cleaning the panels. The surfaces of the panels that are dirty or oxided can be cleaned with water and soap with a soft brush. The pressure of cleaning water can be applied up to 50 bar, but the jet must not be too close or perpendicular to the surfaces. Near the junctions, the water must be directed along an angle sufficient that does not compromise their watertightness.
