13. Condition of Supplied Panels

a. It should be noted that Privacy Smartglass is NOT as optically clear as normal float glass and that there will always be an element of haze within the switchable glass panel. This will not be considered a fault or constitute reason for return or refund. It should also be noted that ambient lighting conditions will have an effect on visible haze and that direct lighting onto the switchable glass panel should be avoided as this will accentuate the haze level; as will viewing the switchable glass from an oblique angle. To minimise the appearance of haze a tinted glass (bronze, green, blue, grey) can be used instead of clear glass. It is important to be aware that SMARTGLASS SOLAR and BLACK-OUT products have a blue tint in the transparent state. This occurs due to the chemistry of the switching molecules. Potential purchasers of these products need to consider this before placing orders.

b. Diamond Switchable Glass Ltd promises that all products will be sold of merchantable quality, fit for purpose and as described. Caveat emptor, the purchaser is responsible for ensuring that the goods they are purchasing are the goods that they expect to receive.

c. Diamond Switchable Glass’s Privacv Smartglass™ panels will have a clear border from the edge of the glass to the switchable area of up to 5mm in width on the long edges, 10mm on the short edges and 15mm on the bus bar edge, this will always remain in the clear state with power on or off. This is the industry standard and will not merit cause for rejection.

d. Diamond Switchable Glass’s Solar Smartglass™ & Blackout Smartglass™ panels will have a painted frit border of 20mm around three edges with a 30mm border on the busbar edge.

e. During any inspection for clarity of the switchable glass panels, the distance between the eyes of the inspector and the film should be 1000mm. The angle of the glass surface and the eyes of the inspector should be 90° (+ / – 10°). At inspection, the ambient brightness of the environment should be 300-500 Lux and the visible spectrum range should be between 400nm- 700nm.

f. Permissible spot or scratch defects in the vision area: Visual imperfections will only be considered as unacceptable when visible from a distance equal to or greater than 2 metres from the surface of the glass. Any defect less than or equal to 1.0mm is permitted

g. Wave distortion or rippling effects: In certain lighting conditions and environmental surroundings a wave pattern may be observed in items reflected in the switchable glass. This can occur in either the on or off states. The visual clarity of items viewed through the glass is unaffected and it is not considered a fault.

14. Silicone

All acidic and many neutral-based silicones are extremely hazardous to switchable glass products and can cause de-lamination and irreversible damage. In any instance that silicone is to be used; only the Diamond Switchable Glass Ltd Approved Silicone that has been expressly specified for use by Diamond Switchable Glass Ltd in conjunction with its switchable glass product may be used. The use of any other silicone will invalidate the warranty and may cause harm to the switchable glass panels.

15. Installation / Fixings

a. Any installation carried out by Diamond Switchable Glass Ltd does not include the final electrical connections made to the mains 22O/24OV power supply. This must be supplied by a fully-qualified electrician that is appointed by the Purchaser.

b. Diamond Switchable Glass’s switchable panels can be fitted into UPVC, Steel, Aluminium or Timber frames. Where switchable panels are fitted into timber frames, the section of this frame must be formally approved by Diamond Switchable Glass Ltd prior to installation, or the warranty may be invalidated. All Joinery and framework that Diamond Switchable Glass’s switchable panels are installed into must meet the GGF Official Standards. Failure to meet these standards may result in the invalidation of the warranty.

c. Where door mechanisms / fixings such as door handles, pivots, strike boxes, locks etc. are to be fitted to the Smartglass panels, care should be taken when fitting, as any excessive pressure will cause irreversible damage around the fixing area such as de- lamination or clearing of the liquid crystal. In these circumstances, this will not be covered by the Diamond Switchable Glass Ltd warranty unless expressly approved prior to installation.

16. Operations and Maintenance

a. Smartglass lnternational’s switchable glass panels are designed to be switched on and off regularly. Diamond Switchable Glass Ltd recommends that panels be LEFT IN THE OFF POSITION FOR AT LEAST 6 HRS/DAY (i.e. no current going through the panel). Failure to do so may affect performance and invalidate the warranty. This point is application / usage dependent and the final product construction also needs to be taken into consideration. Should this be of a concern please contact your local representative to discuss in further detail.

b. Once installed correctly, maintenance of the Diamond Switchable Glass Ltd switchable is similar to any glazing solution. Regular cleaning is advised to keep the glass operating at its optimum clarity.

c. It is recommended that all consumable items (i.e. the power transformer, the remote control switch and receiver etc.) are checked annually and serviced if there is any fault to be found.

17. Warranty

a. In the event that the materials supplied by Diamond Switchable Glass Ltd develop a fault which is considered to be due to bad workmanship or material fault within the warranty period, Diamond Switchable Glass Ltd will repair or replace at their discretion, such items to the original supply specification. Diamond Switchable Glass Ltd will not be held responsible or accept any costs incurred by others which are associated with access, removal or replacement of the goods.

b. Due to the manufacturing techniques and materials used, each batch of PDLC is manufactured individually. If a Smartglass panel is replaced under warranty supply it may be possible that the new product may have a difference in appearance. This could be in both the ‘on’ and ‘off’ states of operation in comparison to the original panels supplied on the project. This is not considered a fault of Diamond Switchable Glass Ltd and as such not a reason for further rejection and replacements.

c. Spontaneous Glass breakage following receipt and acceptance of Smartglass Delivery is not covered by any warranty

d. Where glass is replaced under warranty only the period remaining from the original warranty applies to the replacement glass.

e. Please see Diamond Switchable Glass Warranty Document for further information.

18. Product Data

The Smartglass Handbook which is available upon request from our office, or available for viewing on our web-site, should always be reviewed by the customer for specific instructions on the products.

19. Design

Diamond Switchable Glass Ltd reserves the right to modify the design/ materials of its products at any given time with just cause without notification to the client beforehand. While all efforts will be made to keep customers fully up-to-date of any changes to the production, this will not give the client any right of complaint.

20. Tolerances

A bending/bowing tolerance of up to 3mm per meter in glass length is accepted as being within tolerance and will not be cause for rejection or be considered as defective.

21. Force Majeure

Diamond Switchable Glass Ltd shall not be liable or deemed to be in breach of any agreement by reason of any delay in performing any of its obligations of these terms and conditions if the said delay is due to Force Majeure or any causes beyond the reasonable control of Diamond Switchable Glass Ltd.
