.0 Technical description of the Facade system with Hidden Fixing - INVISIO. General The INVISIO façade system includes a fire-proof façade panel, Trimoterm FTV INVISIO, with an invisible intermediate fixing designed for multi- field installation of panels sized up to m, with no visible intermediate fixing. The final appearance of the façade is uniform with the architecture of clear shapes. The construction is extremely fast and economical, with few fittings and secondary finishing. The intermediate fixing has a high level of load-bearing capacity and utilises the load-bearing capacity of the panel to the fullest, without any weakening caused by fixing. The system is designed for vertical and horizontal installation (Fig. and ). Trimoterm panels FTV HL (hereinafter referred as FTV INVISIO) are fixed to the intermediate supports of steel façade constructions or concrete constructions with installed steel profiles by means of a purpose-built line gasket. The line gasket serves to divide the loading capacity to a larger bearing area. The longitudinal edge of the adjacent panel covers the line gaskets and screws of the attached panel in such a manner that they are not visible on the finished façade. The fixing point is shown in cross-section in Fig. 6. The line gasket is attached with a single or double screw according to the thickness of the sub construction and static conversion. The INVISIO system of façades ensures excellent technical characteristics, long life span and a high level of creativity in designing the façade. The range of use of the INVISIO facades is extremely wide. They are appropriate for business, commercial, representative and industrial facilities.

. Panel Composition The fire-proof Trimoterm FTV INVISIO panels are composed of two shallow profiled, galvanised and colour-coated steel sheets (0.6 mm or 0.7 mm thick). The sheet metal is glued to the panel core made of non-combustible laminated mineral wool of the A (En ISO 8) type, which ensures excellent thermal and sound insulation of panels as well as the highest fire resistance. All three layers are bonded to form a composite element (in a thickness of 50 to 0 mm) that fulfils the required load-bearing capacities, tightness and wide construction possibilities. A polythene foil is glued to the surface of the panels, functioning as protection during handling, transport and mounting. After the mounting is completed, the foil is removed. The length of the panels is up to m.. Technical data..

.. Coatings The sheet metal is coated with an anti-corrosive protection of 75 g of hot zinc layer (Zn)/m (EN 0, EN 07) and a protective colour applied with the Coil Coating procedure. The protective colour can be selected according to the use and level of protection. The coating thickness limits the maximum thickness of the sheet metal. Types of protection and individual thicknesses of sheet metal are shown in Table. The surfaces must be checked and cleaned at intervals, depending on the level of air pollution and aggressiveness, within the framework of regular maintenance and in accordance with the instructions on maintenance, or at least once a year.

.0 Design Procedure. Panel Thickness Selection of Trimoterm FTV INVISIO Based on the investor s wish, the Trimoterm FTV INVISIO panel, fixing and the required sub construction for fixing is determined in accordance with the legislation. The basic information required for designing is:. Information on the facility (location, type of the facility, purpose of the facility, desired appearance of the facility, thermal insulation, etc.). Information on the façade element: - Panel thickness - Type of sheet metal and panel (sheet metal thickness and colour) - Modular width - Panel length. Determining the type of mounting and execution of details On the basis of input data, the following is determined:. The load on the panel and sub construction. Sub construction and type of fixing: - Allowed distances or the range of the panel - Minimum bearing area of the panel - Fixing. Allowed distances and Minimal Bearing Area of the Panel The façade element requires a static evidence of the load-bearing capacity in accordance with EN 509:006 or national provisions. The conversion must be performed for a concrete installation and loads. To help you with the selection and design of the façade, a Table of allowed distances has been produced, listing the allowed distances and minimal bearing areas for construction. The allowed distances are listed in the annex of the instructions and are intended for informational purposes. The detailed distances between supports need to be calculated individually for each facility. The conversion of allowed distances is available on the Trimo Technical Service web site. The main factors for determining the fixing are:. Wind load: - Basic wind load, - Height of the façade above the terrain, - Position on the façade (edge areas).. Temperature load: - Panel colour (group I, II or III).. Static system of panel laying: - Single-field, double-field, multi-field.. The manner of panel mounting - Horizontal installation, - Vertical installation, - Single-field, double-field, multi-field. Considering the listed factors, the façade can be subjected to various loads. The allowed distances or the sub construction and the fixing manner must be adapted to the loads.. The Manner of Fixing Fixing of the FTV INVISION panel is a combination of edge and intermediate fixing. The intermediate fixing is the same for horizontal and vertical installation. Edge fixing depends on the manner of installation and comes in various forms. No.6/V-/0-0 5

.. Fixing in Vertical Installations Vertical mounting is performed on the prefabricated foundation girder to which a panel is positioned. The weight of the panel is transferred on the foundation girder. Two types of fixing are used: vertical mounting with edge fixing (Fig. 6) and vertical mounting without edge fixing (Fig. 7). In the system without edge fixing, the minimum distance of fixing in the joint must be at least x = 600 mm from the edge in order to ensure appropriate loadbearing capacity of fixing in the joint. In that case, the load-bearing capacity of the panel in an overhanging position must be checked statically.

.. Fixing in Horizontal Installations Two basic types of fixing or transversal extension of the façade for horizontal installation are used: horizontal installation with mask (Fig. 8) and horizontal installation with fixing by means of Al profile with the HF0 label (Fig. 9). In the case of façade extension with mask, the edge panel is attached with two screws on each side. Edge screws transfer the weight of the panel and wind load.

In order to transfer the load of the panel s weight, the back sheet metal of the panel must be additionally screwed to prevent the settlement of the entire façade. The fixing of interior sheet metal is performed in various manners described in Chapter..

.. Intermediate Fixing Intermediate fixing is a combination of screw and expansion element (Fig. 0, ) and a (sub) construction. The line gasket takes over one load direction through the screw and the sub construction takes over the other load direction. Intermediate fixing is fully functional when both panels are in contact (Fig. 0). Noncorroding screws without a washer should be used for fixing. Fig. 0: Fixing to an intermediate support detail Fig.: Expansion element detail Panel Trimoterm FTV INVISIO Self tapping screw without washer Expansion element Line gasket In general, the minimum required bearing area on the intermediate support for an appropriate positioning on a sub construction is 60 mm or is determined by static conversion (Fig. ). In the case of fixing for a thick wall sub construction, the line gasket is attached with two screws. In this case, the minimal required surface of the sub construction is 80 mm or is determined by static conversion (Fig. ). Number of screws is determined calculation of statics. It is dependent on the load and the thickness of the sub-structure. Fig. : Attach a single screw Fig. : Two screws fixing Self tapping screw without washer Expansion element 8 No.6/V-/0-0

.. Edge Fixing... Edge Fixing - Vertical Installation In the case of fixing through the panel (edge support), stainless steel screws (Fig. ) with a stainless steel washer (9 mm in diameter) and an EPDM gasket should be used exclusively. The fixing should be performed at least 5 mm from the edge of the panel. Fig. : Detail of edge fixing through a panel Panel Trimoterm FTV INVISIO Self tapping screw with washer... Edge Fixing with an HF0 Aluminium Profile - Horizontal Installation Edge fixing in a horizontal installation with a purpose-built HF0 profile is performed by means of fixing of the profile to the steel construction. The profile is screwed directly into the flange if it is not thicker than mm (Fig. 5) and is within the prescribed tolerance, or through a spacing profile, welded to the construction (Fig. 6, 7). Screw lengths according to panel thickness are listed in Table.

.. Edge Fixing with an HF0 Aluminium Profile For fixing the horizontal façade, a purpose-built extruded HF0 aluminium profile is used, which is composed of a load-bearing section (HF0/) and a cover (HF0/). The loads are transferred from the panel through the gaskets (pos. in Fig. ) to the profile, which is fixed to the load-bearing construction of the facility by means of self-tapping screws (Fig. ). In order to transfer the weight of the panel, the back sheet metal of the panel must be additionally fixed. The additional fixing can be performed in various methods according to the sub construction and thickness of the panel (Fig. 6, 7, 8, ). The channel of the exterior joint is sealed with sealing putty and a PE gasket.

.0 Recommendations for installation. Preparing Element Prior to Installation.. Removing Protective Foil A protective foil for the protection of varnished surfaces against any possible damage caused during transport, handling, and assembly, is applied to INVISIO façade panels on both sides. Immediately before placement of the INVISIO façade panels to the assembly location it is necessary to:. Completely remove the protective foil on the element s internal side. Partially remove the protective foil on the element s front side, that is on fixing locations, both longitudinal joints, under edges, etc. (Fig. 6 ). Fig 6: Removal of the protective foil NOTE: - If façade panels are stored for a long period of time, the foil should be removed within three months, at the latest. - If the façade panels are to be stored in the open, they should be protected against the sun; otherwise the complete removal of foil is no longer possible. - During assembly, the foil must be removed from all joints of the façade panel... Elements Cutting Invisio façade panel are made in accordance with project requirements and their cutting is generally not required! In case cutting is needed, only the use of sheet metal shears and saws that do not overheat the panel is allowed (Fig. 7). Use of a circular saw is recommended. Fig. 7: Elements cutting is allowed sheet metal shears and saws Recommended use Restricted use NOTE: - Marking and scratching with nails or similar sharp objects that can damage the protective paint layer is strictly prohibited. - Use of any disc grinding machines and welding devices destroys the anti-corrosion protection. - Small metal particles that appear as a result of cutting and drilling MUST be immediately removed from the surfaces of panels by completion of the day s work at the latest (metal particles exposed to moisture cause corrosion).

. Base requirements and tolerances for Trimoterm FTV INVISIO The base onto which the panel can be attached is a concrete wall, skeletal concrete structure, steel structure or brick wall. Trimoterm FTV INVISIO panels can be attached directly to steel if substructure accuracy is sufficient and the substructure is less than mm thick. Before installation, check the measurements of the (sub) structure to which panels Trimoterm FTV INVISIO is attached. The structure must be within a +/- mm tolerance of the two extreme edges of the panel by length (Fig. 8). The steel structure to which the panels are attached must adhere to ENV 090- or internal Trimo requirements. This means that the construction can deviate from ideal project lines by no more than +/- 5 mm. Fig. 8: Structure tolerances based on distances between two fields The most important thing when designing and beginning the installation is, in addition to the above mentioned, deviation of the base beam. The base beam must be aligned and can deviate by a maximum of 5 mm at a distance of a single multi-field panel (Fig. 9). Otherwise, the panel will not be horizontal, which will cause deformation of the bottom joint. The load bearing profile of the base beam must be levelled using a spirit level.

. The Installation of Intermediate Support Intermediate fixing is a specific feature of the Trimoterm FTV INVISO panel. Intermediate fixing enables the installation of extremely long panels, which would not bear the load in the case of classic installation with edge fixing only, causing the panel to collapse or even fall out of the wall. Fixing of the INVISIO panel is always a combination of edge fixing (the same as with the regular panel) and intermediate fixing, which additionally holds the panel. The proper manner of fixing is shown in the figure below (Fig. 50). Fig. 50: The proper manner of fixing Intermediate fixing requires special attention, as the fitting should not be over-tightened, which causes a pre-deformation of the exterior visible surface and impairment of the exterior appearance of the facade (Fig. 5) or disables the assembly. It is recommended that a minimum inlet of air at the intermediate supports (Fig. 5) be allowed. Figure 5: Recommended fixing of intermediate support Fig. 5: Inconret manner of fixing No.6/V-/0-0 5

. Manipulation and lifting panels The installation begins in the edge axis of the individual façade. Prior to the commencement of the installation of panels, it is necessary to check the geometric correctness of the sub construction, which is a prerequisite for a quality execution. Any possible geometric irregularities must be corrected by a suitable cutting of initial and end panels. The panels are leaned against the base frame, which partially bears the vertical loads. For lifting and positioning the panel to the installation spots in the event of vertical or horizontal façade, the use of vacuum grips is recommended (Fig. 5, Fig. 5). Prior to lifting, the protective foil must be removed from the spots where the panel is sucked by the vacuum grip. A special grippers is also designed for vertical in horizontal installation (Fig. 55, 56). The dimensions of the grip and pins must be determined aesthetically according to the thickness and weight of the panels... Vertical Installation Fig. 5: Vertical lifting with mechanical gripper Fig. 5: Vertical lifting with vacuum gripper For lifting the panels with a thickness of 60, 80 and 00 mm, grips with pins φ mm are used, and for panels with a thickness of more than 00 mm, gripper with pins φ 6 mm are used (Table 8). Bores for pins are made on spots that are later covered with masks.

.. Horizontal Installation For lifting panel INVISIO can be used mechanical gripper (Figure 55). One pair of grippers is designed for lifting panel with a maximum weight of 00 kg. Type of gripper is determined by the thickness of the panel (Table 9). Instructions for using gripper is described in document TD 65.

5.0 Packing, Transport and Storing Information about packaging,transport and storage can be found in document no. 9 Packaging, Transport and Storage. 6.0 Maintenance of Buildings 6. Annual Service Inspection of Façade The service inspection of the entire building and façade should be performed at least once per year. The purpose of the annual service inspection is detection and repairing of eventual deficiencies and thus prolonging the façade s life-span. The annual service inspection includes: - Cleaning of all dirt and, if necessary, washing of the façade. - Eventual damage to the façade must be repaired immediately when noticed. The damaged spots are mechanically cleaned with fine abrasive cleaner (Scotch breit M600), dusted and digressed (cleansing alcohol, isopropyl alcohol). Then a layer of foundation paint is applied to the surface (air-dried coating based on epoxy binders and Zn pigments) and after that the final protection (air-dried coating based on polyurethane or acrylic binders). 6. General Recommendations - Use of the aggressive substances for cleaning façades is not allowed since they may cause damage to the anti-corrosion protection. - Use of disc grinding machines (disc-cutting machines) near the panel is strictly forbidden, to prevent hot particles from damaging the varnish of panels. - In the case of any additional questions regarding building maintenance or eventual necessity of damage repairs, consult the Trimo Service Department. 7.0 Warranty The guarantee and warranty conditions are listed in the warranty statement. 8 No.6/V-/0-0
