Experienced Professionals
KEL Privacy Switchable Glass is engineered to provide innovative solutions for privacy, decrease of solar heat gain, improved comfort, security and aesthetic design while delivering the exceptional performance of fire-retardancy and sound insulation. On top of that, it can also serve as a whiteboard and projection screen, interactive touchable surface etc. At present, it has been a more hygienic and low maintenance solution over the traditional shading solutions.
KEL Privacy Switchable Glass integrated with latest generation of insulated glass unit that combines the technology of smart glass with insulated glass, which provide improved performance for thermal and sound insulation with privacy on demand in addition to glass partition, sunlight control, UV & IR cut, , enhanced security and design as well.
The smart film (PDLC) interlayer attached on the inner surface of one glass panel, then combined with a second glass panel to form a sealed unit. This energy-saving product requires no maintenance or special cleaning needs, which is user friendly and easy to use.
We also offer a triple glazed unit for option, which incorporated all the benefits of triple glazing with the latest smart glass technology. It gives users impressive efficiency, outstanding solar heat gain, thermal insulation, sound protection and further improved security & comfort.

SWITCHABLE GLASS METHODOLOGY
- What Is Smart Glass?
Smart glass is dynamic, allowing a traditionally static material to become alive and multifunctional. This technology allows for the control of various forms of light including visible light, UV, and IR. Smart privacy glass products are based on technologies that allow transparent materials (like glass or polycarbonate) to switch, on demand, from clear to shaded or completely opaque.
The smart switchable glass technology can be integrated into windows, partitions and other transparent surfaces in various sectors, including architecture, interior design, automotive, smart retail windows, and consumer electronics.
The term smart glass mainly refers to active technologies in which privacy glass films and coatings, activated by an electrical charge, change the appearance and functionality of the glass.
Types of active switchable glass technologies and their common applications :
• Polymer Dispersed Liquid Crystal (PDLC) glass, eg: typically seen in privacy partitions in various industries
• Suspended Particle Device (SPD) glass, eg: windows that tint to shade as seen in automotive and buildings
• Electrochromic (EC) glass, eg: coated windows that slowly tint for shading.
Polymer Dispersed Liquid Crystal (PDLC)
The technology behind PDLC films used to create smart glass contain liquid crystals, a material that shares characteristics of both liquid and solid compounds, which are dispersed into a polymer.
Switchable smart glass with PDLC is one of the most commonly used technologies. While this type of film is generally used for indoor applications, PDLC can be optimized to maintain its properties in outdoor conditions. PDLC is available in colors and patterns. It is generally available in both laminated (for newly fabricated glass) and retrofit (for existing glass) applications.
PDLC switches glass from dimmable degrees of opaque to clear in milliseconds. When opaque, PDLC is ideal for privacy, projection, and whiteboard use. PDLC usually blocks visible light. However, solar reflective products, such as the one developed by the material science company Gauzy, allows for IR light (which creates heat) to be reflected when the film is opaque.
In windows, simple PDLC limits visible light, but does not reflect heat, unless optimized otherwise. When clear, PDLC smart glass has excellent clarity with a minimum of 2.5 haze depending on the manufacturer. In contrast, Outdoor Grade Solar PDLC cools indoor temperature by deflecting infrared rays, but does not shade windows. PDLC is also responsible for the magic that enables glass walls and windows to become a projection screen or a transparent window instantly.
Because PDLC is available in a variety of types (white, colors, projection support, etc), it is ideal for multiple applications across diverse industries.
Curve Laminated Switchable Privacy Glass
Curved switchable glass is smart glass that can switch between clear and frosted, but it’s fabricated in a curved or bent form instead of being flat.
It combines two advanced techniques:
- Switchable Glass Technology (PDLC or Electrochromic layer)
- Glass Bending/Curving Process (thermal or cold bending)
Switchable Privacy Glass for Facade
Switchable Glass (also called smart glass or PDLC glass) is a type of architectural glass that changes from transparent to opaque (or frosted) when powered by electricity. For facade applications, it allows a building’s exterior to adjust privacy, glare control, thermal comfort, and even energy efficiency dynamically.Switchable Glass (also called smart glass or PDLC glass) is a type of architectural glass that changes from transparent to opaque (or frosted) when powered by electricity.
