Description®larson is a composite panel designed for creating building facades. It is made from either two aluminium laminates or two outside laminates of various

metals such as copper, stainless steel or brass. These are joined together by a thermoplastic resin polyethylene (PE) core or a mineral (FR) core.

In a sophisticated manufacturing process which gives an extraordinary strength, the double than the normal standard for these types of union.

®larson has an excellent capacity to be machined, drilled, bent and curved without losing its technical characteristics.

Mineral FR core

®Light, flat and fire resistant. Three features that seem to be incompatible and which combine together in larson fr composites. Developed in Alucoil´s ®Research and Development department at Miranda de Ebro, Spain, the larson fr ACM is adapted to maximum security demands in most of European

regulations. Two high quality aluminium sheets and a particular internal FR core that guarantees extreme fire resistance.

®larson fr is the solution to modern architecture´s demands with regards to external facade cladding. The special features of the FR core allow this material, within the range of Alucoil´s composites, to achieve European fire classification Bs1d0, which is specified in the standard norm EN 13501-1, “Fire classification of construction products and building elements”. The classification can be used in many European countries to show compliance with the national building regulations.

Fire classification

Fire tests of building products Standard 13501-1

Class A1: For homogeneous products (without additional classifications).Class A2: For homogeneous productsClass B: A product candidate for this class must be tested according to UNE EN ISO 11925-2, exposure time 30s.Class C: A product candidate for this class must be tested according to UNE EN ISO 11925-2, exposure time 30s.Class D: A product candidate for this class must be tested according to UNE EN ISO 11925-2, exposure time 30s.Class E: A product candidate for this class must be tested according to UNE EN ISO 11925-2, exposure time 15s.

Additional classifications: s1, s2 and s3 for the production of SMOKE.These additional classifications are coming from the measurement data of the testing in accordance with standard EN 13823.

Additional classifications: d0, d1 and d2 for drops / particles in flame.These additional classifications are coming from observations of dropping and particles in flame:

For Class E: UNE EN ISO 11925-2 (d2For class B, C and D: UNE EN ISO 11925-2 and EN 13823 (d0, d1 or d2).

Fabrication of the composite panel

®The advanced manufacture of larson composites brings out an extremely tight adhesion between the different layers and coats. Tests carried out on all our products have exceeded by twofold parameters recommended by various standards. Thanks to the perfect bond between the various parts that

®make up the larson composite panels, they have an enormous capacity for being machined in various ways. All works detailed bellow shall be carried out at temperatures over 10ºC:

Cutting®Cutting of larson composite panels must be done preferably with shears or guillotines, vertical circular saws or in CNC machine centres, using the

appropriate tools.®Due to the exceptional characteristics of larson metals stainless steel, it is recommended to be cut with shears or guillotine.

Routing®larson can be easily worked with routing machines, conventional CNC centres and portable routing machines. The following considerations must be

taken into account:

Curving

®The larson composite panel can be curved without difficulty in curving machines of three or four rolls, ensuring that they are clean to avoid damaging the material.

General Specifications:®Curving of larson composite panels of 3 or 4 mm thickness.

Manufacturing dimensions:Curving maximum width: 4000 mm (Length of the curving machine ).Minimum radius: 150 mm.

®larson metals stainless steel. Minimum radius: 1000 mm.®Curving of 4mm thickness larson Cassette with folded edges.

Minimum bending width: 150 mm (the same as the caps width). The distance between the caps will the same as the thickness of the panel, so that it will be through that separation where it will move during the curving.

Manufacturing dimensions:Curving maximum width: 4000mm. (Length of the curving machine).Cassette folds: 25 mm

It is not recommended to curve cassettes with a edges of more than 30 mm as the edge could be distorted. To carry out the curving process, it is required to put a 2 mm thick aluminium sheet between the panel and the caps in order to avoid the marks of the teflon caps. If we don´t put this sheet between the panel and the caps, marks will be observed on the cassette. If the curving radius is bigger than 1000 mm, the curving must be done in flat, bending the edges afterwards. For this purpose at the beginning the curving radius will be less than the intended one, reaching the desired radio during the forming of the cassette. Anyway, with this type of curving, the edge of the cassette does not remain completely flat and it is possible to appreciate some waves on it. The bended cassettes with edges must have an opening, minimum of 400 mm, to allow the removal of the cassette. In the case of larson

®metals stainless steel the curving will be done in cassettes with edges of 40mm.

®®Due to the low rigidity of the composite panels of 3 mm, it won´t be possible to curve the larson and signi panels of 3mm (cassettes with edge) due to ®

®the distortion that the edge would suffer during the curving. Because of that the curving of the larson and signi of 3mm will only be done on flat panels. There will be plain areas at the beginning and the end of the curving area with maximum length of 140mm.

Bending

The panel should be protected in the area in contact with the tool and the leaning area to prevent damages.

Types of routinga) Bending to < 90º, with tools which their angle gets a perfect cut at 90 º.b) Bending between 90 ° <180 °, with tools which their cutting angle achieve a perfect folding at the customer’s requested angles.c) To get the desired length, folding should be always in the axis of the routing as shown here.

Drilling

®larson can be machined with conventional aluminium and metal drills. The drills used are the normal ones for these types of jobs. It is helpful for drills to be adaptable with a central end to avoid slipping and ensure perfect positioning.

Riveting

The fixation of the panel to an aluminium profile will be done with aluminium rivets with an stainless steel rod of 4'8 x 16 mm although this may change due to the thickness to be riveted. It is obligatory to use a special positioning mouthpiece to avoid damages on the panel and to place the rivet perfectly. The thermal expansions must be taken into consideration so that the panel can expand freely due to the weather conditions.

®Bearing in mind the following nomenclature, Alucoil offers a wide range of punches able to give each type of facade exclusive design.

“R”: Round (Diameter of perforations).“U”: Perforations disposed in parallel (Distance between axes).“T”: Perforations in a staggered formation (Distance between axes).“C”: Square (Side of square).“LC”: Side of the square (Width x Length).“LR”: Rectangles with radius (Width x Length).

The non perforated perimeter will be indicated by the type of perforation and tool used for each case.

To combine different diameters within the same panel, or special perforations. Please request.

ImportantAll fabrication jobs must be done using protection gloves and security goggles to avoid wounds or injures by shavings.

®All fabrication jobs of larson composites must be done with the protective plastic film to avoid damages and at temperatures above 10ºC on coated surface.The plastic film must remain until all processing jobs have been finished. Routing must be done on the reverse side opposite of plastic film surface.

Hammer and Stucco Embossing Finishes have especial mechanizing instructions due to its roughness.It is necessary to keep 1mm in total (including 0.5mm of aluminium sheet) so the machining does not affect to the aluminium foil, in CNCmechanizing centre must be screwed.Coated sheet bending must be done according to the T-bend described on the technical data sheet of each finish

Wind loads

To scale the cladding with cassettes against wind loads, it is to be considered as an acceptable maximum deflection at the center of the cassette of L/30, (1)where L is the width of the face side of the cassette .

®• larson cassette of thickness 4 mm .• Allowable stress in the the panel σadm = 51Mpa.• Maximum profile deflection: L/200, where L is the distance between brackets.• Safety factor y = 1.75 including.

(1) These values of deflection do not involve degradation or a residual or permanent distortion of the cassette, but if they can suppose punctually an undesirable aesthetic appearance, therefore if the designer wants to reduce the maximum acceptable deflection, he shall contact with the beneficiary.

®Lineal thermal expansion of the larson composite panel and the profile support

Due to the thermal influence, the magnitude of the contraction or expansion has to be calculated for the dimension of the joint expansions. This is defined by:

-6Where is the coefficient of expansion of the composite panel and the aluminium (24. 10 ).

Taking into account that in our environment the maximum thermal dispersion is 42ºC, the maximum extension per lineal meter will be:

Therefore, in relation to determine the proportion of the joint expansion, it should be enough to allow 1mm per lineal metre, this should achieve the absorption of expansion, regardless of the time of year it is fabricated, installed and all building work has been completed.

∆L= Еx L = α x ∆T x L-5“α” : 2,4 x 10

-5∆L=2,4 x 10 x 42 x 1000= 1,008 mm

Placing of intermediate reinforcement

Area Preparation and cleaning

Dust and other contaminants will be removed using mechanical processes and never with the use of solvents. The cleaning will consist of a light or intensive sanding of the area (depending on the amount of dirt). This dust will be vacuumed or removed with compressed air.

For the cleaning and degreasing SIKA CLEANER 205 will be used.

Applying Primer to the area

Once the area has been cleaned it will be applied the SIKA PRIMER, a black primer which reinforces the adhesion of the filler. Depending on the cassette

® ®type, larson or larson metals stainless steel, SIKA PRIMER 210 T or SIKA PRIMER 204 will be used respectively.

Double Sided Adhesive Tape

Once the area has been covered with primer and the waiting time for drying has passed (30,60m), the adhesive tape (SIKATACK PANEL 3) will be placed. This will hold the component in position, while the adhesive is curing. This process will also ensure that at least the minimum thickness of the adhesive will be applied.

Applying the adhesive

The application of the adhesive SIKATACK PANEL will always be on the cassette applying a bead next to the double sided tape.

Placing of the intermediate reinforcement

The intermediate reinforcement will be placed where the surface of the panel has been coated with adhesive. The intermediate reinforcement will then be riveted at the top and bottom.

16®larson

Transport, storage and manipulation

The maximum storage period is eight months. It is recommended that the panels are piled up one on top of the other to a maximum of 7 heights, preventing to be placed vertically.

Work start

1. Project design

Before the installation of the system has taken place, in the design phase, the tray sizes and supports must be determined. For this purpose, it is necessary to define at least the following aspects:

• Profiles, brackets and its fixings devices. In particular, it should be defined the maximum batter of the support in relation to the regulation range allowed by the bracket.

• Thickness of ventilated air gap and of thermal insulation boards.

• Type of panel and size of cassettes (standard and special) taking into account the definition of joints between cassettes and the assembly to other elements.

• Singular points resolution.

2. Installation organisation

Both for new or refurbishments projects, firstly it must be studied the aspect of the existing load bearing support. Then, brackets will be fixed to the support. After that, thermal isolation will be placed before vertical profiles. It is recommended rigid hydrophobic and flame- proof insulation boards. Then, the general part of the cladding will be done upwords and after the joints or special pieces (corners, singular points...).

3. Installers

Installation should be carried out by TA holder or its recognized installers.

4. Support preparation

Sub frame must be installed perfectly aligned in order to guarantee the flatness of the system. Before mounting the cassettes, pull-out resistance of brackets must be tested in situ in order to assure the stability and load bearing capability of the support. The installer will give its conformity to the estate of the support before any cassette has been installed. The system must be installed respecting the correct batter and in order to guarantee the flatness of the system.

5. Fixing vertical profiles to brackets

First and last bracket will be installed maximum at 250 mm distance from the end of the vertical profile. Maximum length of vertical profile will be 6.500 mm.

Load bearing brackets will be fixed to the support using self tapping screws complementary to the foreseen crossing bolt, whileretention brackets will allow dilatation movements of the vertical profiles, thanks to the mounting holes previously carried out onthe vertical profile.

6. Cassettes

During the installation of the cassettes it will be necessary to take care on its manufacturing direction sense (marked with an arrow on the protective film and on its hidden face).Once installed, protective films must be removed in order to avoid damages caused by an excessive exposition to UV radiation and weather.

For the purpose of the installation on site, the positions of LC-3 support brackets must be reviewed, and if the modulation allows it, the cassettes will be placed in line, in an upwards sense, placing the slots and the LC-3 and after riveting the cassettes to the wings of the vertical profiles.

7. Inspection and maintenance:

Inspection must be done at least once per year. This period of time may be shorter due to a more aggressive environment where material is placed. Please ask your supplier for advice regarding this issue.

8. Special recommendations:

Eliminate from façade leaves, grass, rust or other strange substances.Cleaning: Any blocking in gutters that may cause overflowing on the façade. Dirt retained in places where rainfall cannot clean it naturally. Defects that may cause an early deterioration of coating or aluminium corrosion must be repaired. If this is not possible replace the sheet.

9. larson composite façade cleaning

®

To obtain the longest lifetime possible for larson façade is important to clean dirt accumulations, dumpings and other materials that may not be wiped naturally by rainfall. All larson cladding material must be cleaned once per year. The cleaning must be done with a soft sponge, wet cloth or with a water pressure system (max pressure 50 bar) avoinding any material that may scratch the finishing (sand, dust...). A neutral soap (PH 6-7) or washing powder or liquid can be mixed with the water (max 10% of detergent in water).

Rinsing afterwards mus be done with clean water that may contain some kind of liquid wax (i.e car washing) and drying after with non abrasive materials and a final wipe with a dry soft cotton cloth.

10. Precaution:

Organic solvents, acid or alkaline products aswell as chlorine products must be avoided on cleaning of coated surfaces. Using strong abrasives, hard brushes and dry cleaning may cause damages to coated surface.

11. Cleaning of fingerprint or similar:

Fingerprints can be removed with acetone application with a non abrasive material such as a soft sponge or leather or cotton cloth. Washing with abundant water comes after and drying with non abrasive materials and with a cotton or similar cloth.
