Controllable Electric Glass Panels: Solarchromic™ Climate Control, Switchable™ Privacy Glass

ESG Ltd

ESG Solarchromic™ Climate Control Glass
With its electronically controllable tint, ESG’s Solarchromic™ Climate Control Glass not only reduces a building’s energy consumption, it is also an attractive design feature for any window, conservatory or rooflight. Available in manual or automatic control, ESG Solarchromic™ panels can be controlled individually or as a multiple panel system.

Digitally responsive, ESG Solarchromic™ Climate Control Glass limits solar heat gain whilst adjusting the amount of glare. Reducing the need for blinds, it helps to create a more comfortable, stylish and sustainable glazed living or working space.

ESG’s Solarchromic™ is not simply a tinted glass. The intelligent glazed system uses electrical impulses to adopt new tones, instantly controlling the transmission of heat and light into a building. As an ideal adjustable solar controlled glass for windows, conservatories, loft conversions and glass roofs, it provides maximum comfort whilst saving a substantial amount of energy.

ESG Solarchromic™ is available in sizes up to 1350x3300mm, custom shapes and sizes, and can be combined with any of ESG’s range of LCD privacy, security or fire resistant glass products for a total glass solution.

Unique Features
• Creates a comfortable environment so that you can fully utilise your conservatory or glass room.
• Low energy consumption (only the change in transmittance uses electrical energy)
• Outstanding heat control in summer and a pleasant room climate
• Shading by dimming the glass instead of mechanical blinds or sunshades
• Significant reduction of glare and an unobstructed view to the outside
• Costs for maintenance of shading systems can be saved
• Reduction in air conditioning costs
• Effective use of solar heating during winter
• Ideal component for "smart buildings"
• ESG Solarchromic™ wellness windows

ESG Switchable™ Glass Electric Privacy Glass
ESG Switchable™ Glass Electric Privacy Glass allows a cost effective creative design solution with engineering flexibility so therefore can be used in a variety of settings. It can be incorporated to curved surfaces, cut into odd shapes or even hole-punched to accommodate specific design applications.

ESG Switchable™ Glass is made of two layers of transparent conductive films 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 the window is clear. When the power is turned off, the liquid crystals return to their normal scattering positions and turn the glass from clear to translucent.

The liquid crystal privacy film is sandwiched between the glass in a way similar to the construction of laminated glass. The outside skins are made up of glass (normally 5 or 6 mm annealed glass) each side, then a PVB interlayer is inserted on each side to trap and hold the liquid crystal privacy film.
The liquid crystal privacy film is made up of electrically conductive coatings, a polymer matrix and liquid crystals. This film has electrical wiring to be connected to a transformer to supply power for the "on" (clear state) mode.

ESG Switchable™ Glass is available in single form or double glazed units.
