Ÿ Not affected by thermal shock and maintains its physical &

mechanical properties.

Ÿ Extreme climate changes such as from0 0

Ÿ -I0 C to +60 C or from a dry climate to

Ÿ 90% relative humidity do not affect the

Ÿ appearance or the properties of the panel

DIMENSIONAL STABILITY

Ÿ With due conditioning of site, moderate

dimensional variation due to the effects of

atmosphere; it contracts in low humidity

and expands in high humidity

environments.

Ÿ The compactness of Samrat Exterior

Cladding panels provide excellent

mechanical properties such as flexural,

tensile, compressive and impact strength.

The homogeneity and high density of the

panels ensure maximum retention.

SPECIALPROPERTIES

INSTRUCTIONS FOR PANEL FIXING

EXPANSION CLEARANCE

The most important characteristic of Samrat exterior cladding

panels are that they marginally change their size in relation with the

changes in relative humidity. They normally expand when they

absorb moisture and marginally shrink when they lose moisture. You

must provide proper clearance between the panels during fixing

process to compensate for this expansion and contraction,

commonly referred as the dimensional change.

You may consider this clearance as per below basic thumb rule.

Panel length = a,mm

Panel width = b,mm

Expansion Clearance = a or b 500

MOUNTING OF PANELS WITH SCREWS ON ALUMINIUM

SUBSTRUCTURE

The dimensions and site aluminum substructure can be considered

accordance With the relevant national standards. The aluminum

substructure generally consists of vertical support profiles/hollow

sections which are mounted on the wall using angle brackets and

rivets.

Metal sub-constructions normally change their dimensions with

differences in temperature. The consideration of change the

dimensions of Samrat Exterior Cladding panels in relation with

changing relative humidity is done by the concept of Expansion

clearance explained above. These changes in size of sub-

construction and the cladding material can also be opposite to each

attention must be paid to the required expansion clearance. Due to

the material properties of Samrat Exterior Cladding panels, fixed

points and sliding points need to be made to fix the panels.

Fixed points are used for uniform distribution (halving) of the

expansion and the shrinkage movements. The diameter of the drill

hole in Samrat exterior Cladding panels has to be made from 5.0 to

6.0 mm.

The diameter of drill hole in Samrat Exterior Cladding panels must

be 8 mm, drilled larger than the diameter of the fastening,

depending on the required expansion clearance. This can be

maintained as the shaft diameter of the fastening plus 2 mm for

every meter of cladding material starting from the fixed point. The

head of the fastening must be big enough so that the drill hole In

Cladding panels is always covered.

The table below is depicting maximum spacing of fastening for

single and double span panels:

FASTENING SPACING

The rivet must be put in place with a flexible mouth piece

having clearance of 0.3 mm.

The fastening is placed in such a way that the panel can move

slightly. Rivets are put in place with flexible mouth piece. The

defined clearance of the rivet head to the surface of the

panel (0.3 mm) allows movement of the element in the drill

hole as shown in figure. The centre point of the drill hole in the

sub-construction must coincide with the centre point of the

drill hole in the Cladding panels. Drills with the clearance

piece. Screws must not be over tightened.

The fastenings should be put in place starting from the

middle of panel to outwards.

EDGE SPACINGS

To ensure the flatness and stability of the cladding panel,

ensure that the edge spacing is maintained properly. The

joints must be made at least 8mm wide so that changes in

size can take place without any obstruction.

EXTERIOR CLADDING FIXING METHOD

The lap Sliding Fixing Method has the advantage of being a very

attractive system of panel fixing. With pre-fabricated Samrat

Exterior Cladding panels for the lap slidings. It is easy to design

robust and modern facades. Besides the regular advantages of

Samrat Exterior Cladding panels, these panels are easy.

Mounting Instructions

1. Preparing the substructure

Samrat Exterior lap sliding panels are installed using mounting clips

fixed to a sub-structure of vertical wooden slats.

each slat must be at least 50 mm wide where two panels join to allow

enough space for two mounting clips side by side. The gap between

each slat should not exceed 500 mm as applicable to low building of

up to 8mm height.

The panels are installed starting from the bottom. First of all, fit a

horizontal base bar. Now fit the first row of mounting clips so they

rest on the bar. Make sure you fit 2 mounting clips at each vertical

joint between panels.

2. Installing the first row of panels

Place the groove along the lower edge of the Samrat Exterior lap

sliding panels into the mounting clips. Secure the panels in place by

fixing mounting clips along the lap edge of each panel. The panel

above overlaps the first row of panels by approximately 25 mm. Fit a

screw next to the lap middle mounting clip on each panel. This is

designed to stop the sideways shifting of panels

13 14

3. Vertical joints

A slot for Fixing the mounting clips must be located at each vertical

joint. Two mounting clips, one either side of the joint, are needed to

provide the necessary hold. Please use proper backing strips to seal

the vertical Joint between cladding panels. If the siding elements are

arranged so the vertical Joints are offset then it is sufficient to install

the panels plus backing strip using of single mounting clip. If the

vertical joints are in a line then two mounting clips need to be used.

There must be a gap of at least 8 mm between the panels at the joint.

4. Outside corners/Inside corners

with mitre

Samrat Exterior lap sliding panels can be mitred for both outside and

inside corners. Outside corners: The lap edge of the panel must be 12

mm shorter than the lower edge of the paneI (regardless of the panel

width). Inside corners: The lower edge of the panel must be 12 mm

shorter than the top edge of the panel (regardless of the panel width).

The mitred edges must have a chamfer. The sub structure needs to

be protected with a plastic sheet to prevent water entering.

Elements can be installed on both outside and inside corners using a

variety of shapes of corner profile. In this case the panels are cut to

size without a mitre. Please make sure there is a gap of at least 5 mm

between each panel and the corner profile.

5. Installing the top row of panels

Secure the top row of panels by fitting screws along the top edge of

each panels. Use screws with painted heads to match the color of the

panels, as used for the installation of full-sized Samrat exterior

Cladding panels.

RECOMMENDATIONS FOR WORKING

TRANSPORT AND HANDLING

Handle Samrat Exterior panels with care in order not to damage the

edges and surfaces of the high-quality material. In spite of the

excellent surface hardness and the installation protection film, the

stack weight of Samrat Exterior Cladding Panels is possible cause of

damage. Therefore, any form of dirt or dust between the panels must

definitely be avoided.

Samrat Exeterior cladding panels must be secured against slippage

during transport. when loading or unloading, the panels must be

lifted. Do not push or pull them over the edge. Transport protection

films must always the removed from both sides at the same time. The

transport protection film must not be exposed to heat or direct

sunshine.

15 16

MACHINING

Samrat Exterior cladding panels can be easily machined, like hardwood, laminated chipboard or bonded chipboord, with carbide-tipped woodworking tools. Saw with stable circular saws or hand-held circular saws for installation cutting. All well-known producers of hand-held machines (Festa, Bosch, Metobo and many more) offer guide rails. We recommend usage of carbide-tipped saw blades with (group) trapezoidal teeth FZ/TR-(Leitz) to give good cutting results. To achieve good cutting quality, feed EXtERIOR as smoothly as possible.

Ÿ Cutting rote: 50-60m/sec depending on tool diameter and rpm, e.g. 4000 rpm, 250 mm, 64 teeth

Ÿ Depth of cut per tooth: 0.02 - 0.04 mm

Ÿ Feed: 6 -10 m/min depending on thickness

Ÿ Sharp saws and optimum setting of the saw blade projection are necessary in order to achieve clean cut edge

Ÿ For fitting work and chamfering on the construction site , electrical hand planes with a chamfering or a mitring groove have proven themselves.

OŸ Use HSS twist for manual drilling. Drill tip 90

Ÿ When using carbide-tipped drills use pillar drilling machines-carbide metal tends to break off when drilling by hand.

Ÿ Do not allow the drill to break through the backside of the panel, or if necessary, drill against an appropriate base applying enough pressure to ensure a clean exit hole.

STORAGE AND AIR CONDITIONING

all panels must be stacked horizontally on flat, stable support and supporting panels. the goods must lie completely flat. Cover plates must always be left on the stack. The top cover should be weighted down. After removal of panels, PE films must again be closed over the stack. The same applies, in principle, for cut-panel stacks, Incorrect storage can lead to permanent deformation of the panels.

Samrat Exterior cladding panels are to be stored in closed rooms under normal climatic conditions, Climate differences on the two surface of panel are to be avoided. with pre-installed fastening elements, therefore, care is to be taken that the climatic effect is uniform on all sides. Use intermediate layers of wood or plastic.

and remove dirt & contaminants Allow the surface to dry. Samrat

recommends Dow corning R40 Universal Cleaner or R41 cleaner

Plus.

2. PRIMER APPLICATION

Apply a thin, uniform layer of primer by hand to the panel surfaces where the 896 PanelFIX adhesive will be applied. Samrat recommends Dow Corning Primer P.

3. PANEL FIXING

i. Pre Fixing - Tape application:

Once the cleaning and primer has been done and is dry, apply Dow corning panelfix Tape continuously and vertically on to the supporting structure. Dow Corning Panelfix Tape, which is 12mm width, 3.2mm thick in Black Color is recommended to be used for the temporary fixation of the Facade Panels during the 896 panelFix Silicon Adhesive curing process. This will also ensure the minimum thickness of adhesive joint as achieved. Pre Fixing Tape provides instant tack and a temporary anchor that holds the panel in position while the silicon Adhesive 896 completely cures and reaches it final bond strength.

Do not remove the upper protective layer from the tape until the

ii 896 Panelfix Adhesive Application :

After tape installation, apply the adhesive on to the supporting structure and also directly to the panel. Apply the adhesive in a continuous operation using a caulking gun, allowing a minimum of 5mm distance from the tape, Extrude the silicon Adhesive with minimal angle between of nozzle and the surface to achieve required joint dimensions.

** After the Silicon Adhesive application, remove the protective layer from the pre fixing tape.

iii Panel Installation:

Position the panel by gently pressing and correcting if necessary. Once in position, apply pressure to ensure that the panel fixing tape is in complete contact with the inner faces of both the panel & supporting structure.

Adhesive fixing should meet the following requirements :

i) There should be a maximum distance between the profiles of

500 mm to 600 mm. apply 896 PanelFix to each profile.

ii) Samrat will take the assistance of Dow Corning while calculating

IMPORTANT INSTRUCTIONSFOR CARESamrat exterior Cladding panels can be mounted in variety of different designs as panels for balconies, railings or fencing.

BASIC

During construction and installation, care is to be taken that the material is not exposed to standing water. This means that the panels must always be able to dry out. Connections of Samrat Exterior Cladding panels to one another always have to be made in the same panel direction. Samrat exterior cladding panels can show deviations from being flat (see EN 438-6, 5.3) and this to be compensated for by the sub-construction being executed so that it is stable and flat. All connections to other components or to the background must be executed firmly. Elastic intermediate spacers to the sub-construction elements which permit a greater tolerance than + 0.5 mm must definitely be avoided.

Samrat exterior Cladding panels can be mounted with rivets or screws. Due to the material properties of Samrat Exterior Cladding panels, fixed point and sliding points need to be made to mount the panels.

TECHNICAL NOTES

The substructure is to be protected against corrosion regardless of the material or system used. Anchoring elements for installation or walls or for installation of the panels must be suitable dimensioned to withstand the local wind loads dimensioned to withstand the local wind loads and meet the local structural requirements. Verifications are to be submitted to the client. The necessary space for expansion according to the manufacturer's recommendations must be taken into account when installing Samrat exterior cladding panels.

CLEANING

Samrat Exterior Cladding panel has a hygienic, sealed surface - it needs no looking after.

cleaning is necessary under certain circumstances. This is most easily done as follows: for cleaning use clean, warm water, clean clothes or rags, and soap (household cleaners which are sold in shops) Avoid scouring substances. For Samrat Exterior Cladding panels surfaces, solvent cleaners can be used for removing, stubborn marks such as varnish, paint sprays (graffiti) etc.

23 24

PRODUCTION

Samrat exterior cladding panels consist of lengths of natural fiber -

about 65% of the weight - and synthetic resins. The panels do not

contain organic hologen (chlorine, fluorine, bromine etc..)

Compounds, such as occur in propellant gases or PVC. They contain

neither asbestos nor wood preservatives (fungicide, pesticide etc. )

and are free from sulphur, mercury and cadmium. The precisely

managed production processes have no negative effects

whatsoever on the environment.

WASTE DISPOSAL

the shavings which arise when machining (cutting and milling) are

not hazardous to health. consequently, even with the thermal

disposal of waste - assuming modern heating plants no

environmental poisons such as hydrochloric acid, organic chlorine

compounds or dioxins can arise.

Samrat Exterior cladding panels combust-with appropriately high

combustion chamber temperatures and dwell times of the

combustion gases in the combustion chamber, as well as on

adequate supply of oxygen-into carbon dioxide, nitrogen, water and

ashes. The energy which results from this can be utilised.

Disposal on well-ordered commercial landfills is not problematic.

always observe the country-specific rules and regulations which

apply to disposal.

WARRANTY

Samrat warrants the quality of Samart exterior cladding panels

within the framework of the given values and test standards.

However, they are expressly not liable for defects in the substructure

or defective installation as they have no control over the execution of

these. The local building regulations are to be followed without fail-

we accept no liability with regard to these. all information

corresponds to the current state of the technology. suitability for

particular applications can not be confirmed in general.
