3 Principle: LCD Privacy Film is made of two layers of transparent conductive film sandwiched with PDLC material. The film is then laminated between two pieces of glass. When electricity is applied to the film the liquid crystals line up and ESG Switchable becomes transparent. When the power is turned off, the liquid crystals return to their normal scattering positions and turn the glass from to opaque. The Liquid Crystal Privacy film is encapsulated between layers of glass in a protective laminate construction. ESG Switchable incorporates 5mm low iron tempered glass as standard considerably higher light transmission However as ESG manufacture the product in the UK customers can select from a wide range of glass types colours to suit their project requirements. The outside are made up of glass (normally 5 or 6mm glass) each side, then a PVB interlayer is inserted on each side to trap and hold the Liquid Crystal Privacy film. Glass Sheets LC Film Interlayer Films PDLC Light Scattering Mechanism Off Manufacturing On ESG Switchable is manufactured in the UK by our experienced team and all stages of its production process are monitored and controlled. ESG employ a variety of laminating methods which enables to produce a wide range of specialist glass products incorporat ESG Switchable. This method allows us: to control our production process very precisely to use different intelayers optimal for specific applications (PVB and EVA) to produce all types of glass: shapes, curved, notches, cut outs, hole to manufacture special products: ESG Secure ESG Pyrotech ESG Acoustic glass The Liquid Crystal Privacy film is made up from electrically conductive coatings, a polymer matrix and liquid crystals. This film is connected to the power supy via bus bars, electrical wiring and a transformer. We use only the best materials in our production process from major global producers, whose materials are manufactured to internationally recognised quality standards.

4 Features & Benefits Where discretion is vital, ESG Switchable gives you the choice of privacy or the public gaze at the flick of a switch. Normally a diffused white which acts as a screen, this LCD glass can be made transparent simply by passing an electric current through it. With the power off, liquid crystal molecules in the Privacy film are randomly oriented so that incidental light is scattered, making the glass opaque; but when electricity is applied, the liquid crystal molecules line up and, as light passes through it, the Privacy film becomes optically clear. ESG Switchable is available in custom sizes and shapes, making it an ideal choice for architects and designers when creating working, home, retail and leisures spaces. In its white state, LCD glass even becomes the perfect backdrop on which to project presentations, without the need for a separate screen.

All necessary 240V wiring ( including switches and power points ) are not part of the ESG installation package. ESG require a 240V 13A plug socket or fuse spur for the power supply to each controller in the installation. If a fuse spur is being used, wiring of the supplied controller power cable into the spur is the responsibility of the onsite electrical contractors. All power source must be withing 0.5m of the installation position of the controller 12

13 Glazing - General Notes Surface Conditions A. Inspect the areas and conditions under which work will be performed. Correct any circumstances detrimental to the proper completion of the work. You must not proceed with glazing until unsatisfactory circumstances are corrected. 1. C. Set the glass in a method which produces the greatest possible degree of uniformity appearance. 1. Indicate clearly when install glass in dynamic frames such as operable windows or sliding doors. 2. Glazing to the exterior and wet interior conditions must be wet-sealed and resistant to moisture with B. Ensure all glazing channels, rebates and stops are free provisions to allow for weeping of condensation from obstructions and substances which may hamper that may infiltrate the system. quality of glazing 3. Pressure glazing systems without positive positioning stops must not be used with this glass. Remove protective coating which might fall in adhes or interfere with bond of sealants Ensure the final wiping of surfaces complies with manufacturers instructions immediately prior to 5. application of primer and glazing compounds or tapes. USE ONLY NEUTRAL CURE SILICONES. DO NOT USE ACETIC SILICONES. RECOMMENDED: DOW CORNING 399, 795, 799, 982, 991, 1199 Glazier to place electrical connections toallow access by an electrician. Electrical connections must exit at the head tion of any framing system using ESG Switchable panels in wet environment applications. D. Cut and seal the joints of glazing gaskets in accordance with the manufacturers recommendations, provide watertight and airtight seals at corners and other locations where joints are needed. Installation A. Inspect each piece of glass immediately prior to start 1. Do not install items which are improperly sized, have damaged edges, or are scratched, abraded, or deficient in any other manner. 2. Do not remove labels which are provided by the glass supplier until directed by the Architect. 3. Adhere to all ESG installation instructions and installation drawings. B. Locate sill setting blocks of standard width and thickness at quarter points of all glass lights unless otherwise recommended by manufacturer or supplier. Protection Reapply protective film after glazing to avoid surface damage proir to commissioning. Cleaning Cleaning can be carried out much in the same way as normal glass by using a slightly damp cloth or professional glass cleaning product. Abrasive products should never be used, particularly when the surface to be cleaned has a reflective coating. ESG advise the use of a professional window cleaning service. Avoid excess moisture / chemical cleaning agents coming into contact with ESG Switchable panel edges. 1. Use blocks of proper durometer, size and thickness to support the glass in accordance with the manufacturers recommendations. 2. Glass lap and edge clearances must be provided according to pertinent codes and standards of manufacturers 13

14 Setting/Glazing ESG Switchable panels may be orientated in any direction. The Flat Glass Marketing Association (FGMA) Glazing Guidelines are to be followed except as noted. Setting Blocks Glass larger than 0.5 square metres should be placed on two EPDM or neoprene setting blocks. Glazing Methods These blocks should have a durometer hardness of 85±5. Interior Applications - Laminated ESG Switchable panels Dry Glazing: This is preferred interior glazing method. Wet Glazing: If a non-acetic sealant is used, it must be compatible with the panel polyvinyl butyral (PVB) interlayer. Never use putty or glazing compound to glaze an ESG Switchable panel. Exterior Applications - Insulated Glass Units made with ESG Switchable Wet Glazing: Pre-shimmed glazing tape and non-acetic sealants are required to create a seal impervious to moisture for all applications. Panel Position: When used in external DGU, ESG Switchable panel MUST BE positioned as the internal panel. Electrical Connections: These must exit at the head of any ESG Switchable panels in wet environment applications. Structural Silicone Glazing Insulate glass units manufactured with ESG Switchable panels sh not be structurally silicone glazed. Frame Design They should be centred at the bottom quarter points (i.e. equal distance). The blocks should be 1.5 mm narrower than the channel width. Lock-strip gasket systems also require setting blocks. Recommendations can be obtained from the gasket manufacturers. Glass Protection Once the glass is installed, the architect, general contractor, or owner should provide for glass protectionand cleaning. Weathering steel or alkaline materials may cause surface damage due to staining. Abrasive cleaners should never be used, particularly when the surface to be cleaned has a reflective coating. Windblown objects, welding sparks, or other material applied to the glass surface during construction may cause irreversible damage. Standard frame edge clearance and face clearances may be used, EXCEPT edge bite must be 11mm minimumand framing must have a hole of 6mm diameter. Tomaintain a proper seal against the infiltration of waterand air, adequate bite is required. Inadequate clearance for the edges can cause damage due to glass-to-frame contact. The industry standard for framing deflection must be adhered to. The deflection must not exceed either the length of the span divided by 175, or 18 mm, whichever is less. All expansion joints and anchors must be designed so that the glass framing does not incur a load due to structural movement. 14

16 Shipping & Receiving Shipping ESG Switchable is delivered by ESG s own experienced logistics team throughout the UK. Full crating and shipping service for export worldwide available. All panels must be checked for damage when the panels are delivered and the delivery note marked accordingly as any claims for damage after the delivery driver has left will not be accepted. This includes delivery of both loose panels and those delivered on stillages. f the person receiving the panels marks the delivery note unchecked or any variation on this term then they will still be deemed to have accepted the panels as undamaged and the panels will be chargeable. ESG will not be held responsible for damage if the person receiving the panels fails to inspect them. Storage Unexpected Breakage Unexplained glass breakage may occur after all precautions have been taken. Such breakage is beyond the control of the manufacturer and therefore not warrantable. This includes but is not limited to the following items: thermal stress damage during sand blasting (if not performed by ESG) glazing system pressures damage during glazing handling and storage problems excessive wind loads objects and debris striking the glass damage by persons/objects at the construction site Glass edges frequently sustain damage due to careless handlingbetween manufacture andinstallation. Handle with care! If the glass is to be stored o site or in warehouse conditions, proper blocking and protection should be maintained at all times. As with other flat glass products, ESG Switchable must be stored where the relative humidity is less than 80% to prevent the glass fm staining. The glass temperature should be held nearly constantto prevent moisture condensation on the anels. Storage temperature range is C. Panels should be tilted at 5-7 from vertical at all times using broad, sturdy uprights to support the weight of the glass. 16

21 PRINCIPLE The laminated glass is put in a vertical position, in front of and parallel to a matt grey screen, and is lit by diffuse daylight or equivalent. The laminated glass is visually inspected perpendicularly at a distance of 2m from the glass, (except for ESG Switchable LCD Privacy Glass which is 1m), with the matt screen on the other side of the glass. Any visible defects that are disturbing shall be marked. Vents are not permitted, nor are creases and streaks allowed in the visual area (Exceptions to this rule exist for ESG Switchable LCD Privacy Glass as detailed below). Where no defects are visible from the specified distance the panel is deemed acceptable. If defects are observed from within the specified distance, the extent of such defects are to be within the tolerances detailed below and if not, then the panel may be rejected. PERMISSIBLE SPOT DEFECTS IN THE VISION AREA Spot defects include opaque spots, bubbles and foreign bodiesdefects less than 0.5mm are permitted. Defects greater than 3mm are not permitted. *For laminates consisting of two panes the maximum size of defect is 2mm. For ESG Switchable LCD Glass products, bubbles of any size are not permitted and any defect both spot or linear type which can be observed from a distance of 1 metre away should be rejected.
