- 3 - INSTALLATION - GENERAL RULES 1. General rules 1.1. Storage Cellular cladding profiles should be stored inside, on a dry, flat and firm base, without direct contact with the ground. While still in its protective sleeving they should not be stored in places where they may be exposed to direct sunlight. 1.2. Transpo (on the pallet) The profiles should be transpo ed in a horizontal position. 1.3. If any visible flaws emerge or irregularities are detected, repo them immediately to the seller before installation. 1.4. Installation temperature The installation should be carried out at ambient temperatures of between 5 C a 30 C. Prior to installation the profiles should be allowed to adjust to atmospheric conditions at the installation site for approx. 24 hrs. 1.5. Dilatation Keep expansion gaps: the change in size due to significant changes in ambient temperature is a natural and inalienable feature of any item of almost any material, including cellular PVC. Therefore, during the installation always mind the necessity of maintaining ca 8- expansion gaps between panel ends and the inside pa s of finishing trims, as shown in the drawings. If the installation takes place in higher ambient temperatures (25-30 C) the clearance should be reduced to ca. 3-4 mm. Bear in mind that with every 10 C of temperature change, total profile length may expand/contract by approx. 0.7 mm per each meter of length. 1.6. Ventilation Keep ventilation gap behind the cladding panels as specified below. Light colours of cladding (white, creme, beige, claystone, light grey, light blue, sand) - ventilation gap of min. 20 mm. Dark colours (anthracite, olive, grey, qua z grey, blue, Wood Design colours) - ventilation gap of min. 40 mm. 1.7. Working with the profiles Cellular PVC profiles and accessory trims can be worked using conventional carpentry tools for cutting, drilling and shaping. Saws with fine-toothed blades should be used and power tools should be operated at the same or higher speeds to those normally used for timber work. 1.8. Do not modify the product by machining its su ace or coating it with a layer of another material. 1.9. Observe all the rules indicated in the instruction for installations and use. 2. Installation 2.1. Preparation of the suppo ing structure The suppo ing structure should be made of timber battens or studs, fastened to walls directly or with the use of metal brackets. IMPORTANT: all battens should be levelled to reduce any su ace irregularities; if necessary, use wedges to level out the irregularities. Timber battens requirements: - should be made of good quality timber, free of knots, the humidity of 15-18%, suitably treated with preservative - should be firmly and reliably fixed using screws / wall plugs or other fixings suitable for the type of substrate - the spacing between intermediate battens/studs directly behind the cladding should not exceed 40 cm centers (max 60 cm for light colours: white, cream, beige, claystone, light blue, light grey) - at the corners of a wall and under joint trims use double battening (or battens of double width) - battens/studs behind the facade cladding should always provide a proper ventilation gap behind the facade panels: a) min. 20 mm for light colours (white, cream, beige, claystone, light blue, light grey, sand) b) min. 40 mm for all other (darker) colours Batten thickness dependent on the wall where the cladding is installed (masonry, timber frame, other). 2.2. Installation of finishing trims Fix the ventilation trims and the sta er trims and at the bottom of the area to be clad. IMPORTANT: in order for the cladding to be installed properly in a level fashion, the sta er trims at the bottom of the walls MUST be level. Keep the ends of sta ing trims at least 5 mm apa to allow for expansion. Fix the inner pa s of perimeter trims over suppo ing battens; fix ve ical trims using specified fixings at recommended intervals of 30 cm. Do not fix outer pa s of the 2-pa trims before panels are installed. The outer pa s should be put aside and protected from damage until ready for use. 2.3. Installation of cladding boards Plan out the places of panel butt-joints on the area to be clad. If a center joint trim is to be used, it should be fixed on suppo ing batten at least of the same width (use 2 battens if necessary). If joint covers are to be used to butt-join adjacent panels, they should be staggered to make a regular pattern on a wall. Cut the panels to required lengths based on that planning. Mount the first cladding board on the sta er trim, ensuring that the back leg of the panel is engaged in the trim slot. Board fixing should commence at the center of its length to the batten through the nailing slot or groove at the top edge, then work progressively outwards. Fasteners should always be placed in the middle of the length of a slot. If a nail slot falls outside a suppo ing batten, use a batten offcut, fasten it to the substrate under the required slot and screw the panel to the timber offcut with a fastener. Always make sure that each end of a board is screwed/nailed to a batten. IMPORTANT: Never drive the head of the fastener tight into the panel su ace, as it may hinder any thermal movement. Keep a small clearance between the fastener heads and panel su ace so that each panel can be moved horizontally left/right after all its fasteners have been screwed to the battens. IMPORTANT: maintain expansion gaps between panel ends and the inside pa s of the finishing trims, as indicated above. The gaps will subsequently be concealed by the outer pa s of finishing trims. All joint covers and ve ical trims must be fixed on suppo ing battens. Joint covers should be installed tight to the panel ends as work proceeds - their spacing lugs will automatically provide proper clearance between adjacent panel lengths. Joint covers cannot be placed directly one over another. Joint covers forming a ve ical line should be separated from each other by at least 2 courses of cladding panels. Provide packing behind any panels cut along the top edge; panel off-cuts may be suitable for that purpose. 2.4. Inse the top pa s of all 2-pa trims to finish the installation. No fixings are required. 3. Information for usage During the use, possible colour changes caused by sunlight, in moderate climate, with air temperatures not exceeding 40 C, at a height of up to 1800 m above sea level, may have a homogeneous nature not exceeding the 3rd degree in the grey scale (EN 20105-A02). 4. Cleaning and maintenance Cellular cladding profiles are finished, practically maintenance-free products. In order to preserve the esthetics we recomend to clean it at least once a year depending on the degree of soiling. Clean the panels and trims using a domestic detergent solution with a temperature not exceeding 40 C. Do not use solvents or similar aggressive and caustic fluids. Wash the su ace with clean water after cleaning.
