2 Page 2 PRODUCT RANGE AKYVER is a light and impact resistant insulating Polycarbonate glazing. The 4, 6, 8 and10 mm depth sheets are available in twin wall form, the 16 mm depth is in triple wall, 10 mm in 4 walls, and the multi wall K Structure is available in 16, 25 and 32 mm thicknesses. AKYVER SUN TYPE Thanks to their special anti ultraviolet treatment by coextrusion, AKYVER SUN TYPE sheets are highly suitable for all outside applications. The homogeneity of the UV absorption layer provides: a long term protection very even distribution of anti UV layer a smooth surface no risk of splintering when the sheets are bent. This treatment ensures excellent weatherproofing as well as protection against yellowing and loss of strength over the years. The treated surface which is to be exposed to sunlight is covered by a blue printed film and marked with a band. APPLICATIONS USES The AKYVER sheets have been specially designed for indoor use : false ceilings, partitions and paneling. The AKYVER SUN TYPE sheets with special anti ultraviolet treatment are suitable for outdoor use:

The AKYVER CONFORT PLUS (fig. 1) sheets, besides their anti ultraviolet treatment, are coextruded with a special coating on the outside which reduces the quantity of transmitted solar energy inside the glazed buildings by decreasing the diffusion of the near infra red rays. The AKYVER DROPLESS (fig. 2) sheets are coated on their internal surface, which reduces condensation and maintains the level of light transmission. They are recommended for verandas, greenhouses and swimming pool coverings. The AKYVER SIGN sheets are particularly suitable for advertising panels or signs.

FIRE RETARDENCY CONVERSION CUTTING SHAPING Thin AKYVER and AKYVER SUN TYPE sheets may be cut with a sharp blade or a cutter. For other thicknesses, it is necessary to use a portable or fixed circular saw. The saw blades must be of high speed steel or, preferably, steel with set in tungsten carbide tips. (80 teeth). For information, we recommend a circular saw with a minimum rotation speed of 3200 rpm (minimum linear speed of 48 m/s). The sheet must be fixed to the bench or wedged on the frame to avoid undesirable vibration.

9 Page 9 CLEANING We recommend the use of a compressed air nozzle (VENTURI type) with a minimum pressure of 6 bars (dry air). DRILLING AKYVER and AKYVER SUN TYPE sheets may be drilled at average speed with a sharp drill (drill at least 10 mm from the edge). Please take into consideration the expansion gap. Drilling diameter : D = screw diameter + 4 mm. WATER RESISTANCE The water resistance of the sheets is guaranteed by using aluminum profiles with neoprene joints. This water resistance can also be effected by using neutral mastics (list on demand). Before using silicone, make sure of its compatibility with polycarbonate. The closing of the flutes must be carried out by following the specifications of paragraph 8. The aluminum profile must also provide good ventilation inside the cells as well as adequate drainage. SUITABLE PROFILES FOR AKYVER SHEETS

10 Page 10 LINKING PROFILES PREPARATION AND SEALING OF POLYCARBONATE SHEETS The sheets are temporary sealed for transport and storage reasons. This protection has to be removed and replaced by a definitive tape when fitting the sheets, in order to avoid dust getting into the flutes. When using multiwall polycarbonate sheets, it is essential to take the best information about the site where they are to be fitted : type of building, activity and exposure. Polycarbonate is permeable to water vapour (approx. 15 g/m2.24h.bar). It is important to take this into account when recommending multiwall polycarbonate cladding. Thus the appearance of condensation may not be a cause of complaint OUR RECOMMENDATIONS - ADVERSE ENVIRONMENTS General use Block the upper ends of the sheet with impermeable aluminum strip and the lower ends with micro perforated tape and cover it with a U shaped profile.

11 Page 11 Use in a specific environment Industrial building with strong risk of dust (dust < 50 μ): sealed using dust proof tape at the top and bottom of the sheets Sports buildings or buildings used by the public : sealed using micro perforated tape at the top and bottom of the sheets Swimming pool or damp atmosphere : avoid the use of adhesive tape. Rather use aluminum U shaped profile or polycarbonate which promotes the evacuation of condensate and cell ventilation. If the environment is polluted or dusty, use aluminum tape rather than micro perforated tape to seal the cells. You must take special precautions on sites which may theoretically appear to be clean, because the sheets can be polluted from other sources : gas exhaust emissions from sites close to heavy traffic routes, chemical industrial environment or industrial chimneys. Thus it is important to use the suitable tape to seal the cells. FINISHING PROFILE The lower parts of the flutes can be fitted with a U shaped aluminum profile for finishing and protection of the adhesive. It is recommended to use a U shaped profile when applying microperforated tape. WATERPROOF SEAL Our experience in using waterproof seals has led us to make the following recommendation : n you must make sure that the seal is compatible with the sheets, because the risk of microcracks occurring due to chemical attack on the sheets is considerable. For this reason, we recommend that you use a SANTOPRENE seal.

12 Page 12 STORAGE The sheets are supplied with polyethylene protection on both sides. For AKYVER SUN TYPE sheets, the side protected against ultraviolet light is covered with a blue printed film. These films must be removed immediately after fitting the sheets. Sheets stored outside must be protected against ambient conditions: sun, rain, etc. Pallets must be set on flat, dry ground. Take all necessary precautions during handling: do not tighten straps excessively; avoid bending which could drive the nails out of the pall et and damage the sheets; do not generate scratches, dents or bulges on the surface or edge of the sheet. Sheets are supplied covered with polyethylene protective film on both sides. For sheets of AKYVER SUN TYPE, the UV treated side which will be exposed to the sun, is identified by a blue printed film and ink jet marking on the edge of the sheet. This film must be removed immediately after applying the sheets. CLEANING Avoid abrasive cleaners that might scratch AKYVER. Use soapy water or water containing a non abrasive detergent. Do not use solvents or alkaline washing powders. Avoid cleaning when the sheets are hot. FITTING AKYVER SHEETS JOINING AKYVER SHEETS USING PROFILES There must be a minimum of 20 mm of the sheet structure inside the profile to give a strong join.

When fitting AKYVER sheets, national regulations must be taken into account. The following tables might help you to determine the size of the sheets and / or the need for the installation of intermediate supports, depending on the load applied on them. Minimum roofing gradient : 8.7 %

14 Page 14 Recommendation extra to technical recommendation When fitting AKYVER sheets, national regulations must be taken into account. The following tables might help you to determine the size of the sheets and / or the need for the installation of intermediate supports, depending on the load applied on them. Maximum sheet lengths or distance between 2 sheet supports (L) in mm for different sheet widths (W) and loads. Maximum deflection = 50 mm. Length of the sheets (mm)

15 Page 15 FITTING AKYVER SUN TYPE SHEETS FOR SKYLIGHTS (CURVED SHEETS) Using the table below, the fitting width (W) in mm can be determined according to different radii of curvature whatever the length of the sheet. When making skylights, it is necessary to pre bend the aluminum profiles in the workshop. AKY VER SUN TYPE sheets will take the curvature of these profiles.
