SPD SmartGlass

In the area of light control, there are three main technologies: polymer liquid crystal devices (PDLC), suspended particle devices (SPD) and Electro chromic devices (EC). All three may be used to produce smart glass, which is described as a glass that can change its light transmission when a voltage is applied. For reasons given elsewhere, SPD is the technology of choice for use in external or solar control windows because of its reliability, price, performance, and manufacturing advantages and aesthetics.

SmartGlass Installation

While it is relatively straight forward for an experienced glazier to install SmartGlass panels and windows we recommend that our highly experienced design and installation teams be utilised to install your SmartGlass requirements. Our installation team will travel anywhere in the World to ensure that you, the customer achieves 100% satisfaction.

Third party glaziers and electrical contractors installing SmartGlass should contact their local representative to receive a copy of the SmartGlass handbook and to receive on the spot advice.

Warning

  • Do not use a dc voltage with either SPD or LC SmartGlass’. If you use a dc voltage, the SmartGlass will not function properly and the dc voltage may polarize the particles. Initially they will let light through but gradually the particles will migrate toward one end of the cell and cluster or pile on top of each other. This leads to a gradual darkening of the glass. The only way to avoid this unwanted darkening is to use an ac voltage. With an ac voltage, the tendency to migrate toward either end of the cell is neutralized.
  • Only neutral cure non acetic silicone should be used when installing SmartGlass. We can supply the required silicone to ensure the safety and longevity of your purchase.
  • We do not recommend applying Smart film to existing glass units and will not supply for this purpose. There are various reasons for this mainly quality, longevity and performance
