EHD Smart Switchable Glass

EHD Smart Switchable Glass is an industry-leading switchable glass solution.

Our cutting edge technology allows you to switch from transparent to translucent and vice-versa at a tab of your fingertip.


How does Smart Glass work?

A simple On/Off mode switches the EHD Smart Switchable Glass from transparent to translucent. In the transparent mode, the smart switchable glass appears just like any other conventional glass panels providing unobstructed view and daylight penetration. In translucent mode, the smart switchable glass acts as an electronic blind providing privacy and security, while still allowing daylight penetration.

In ‘On’ or ‘Transparent’ mode, an electric current is passed through the PDLCs (Polymer Dispersed Liquid Crystal) interlayer which lines up the microscopic crystals along parallel axes, allowing vision through the glass.

In ‘Off’ or ‘Translucent’ mode, no electric current is applied so the PDLCs are arranged randomly in droplets, scattering light as it passes through the film. This results in a blurry milky-white colour obstructing vision through the glass.

Quality Control

With longevity and safety incorporated into the design of our product, you can expect EHD Smart Switchable Glass to have a lifespan of a conventional glass product.

Durability is ensured with over 70,000 hours of non-stop testing when switched to ‘On’ or ‘Transparent’ mode. Toughness and soundproofing are guaranteed with tempered glass measuring 12mm of thickness that few competitors can match. Energy saving is achieved with UV blockage of 98%, allowing occupants to enjoy a comfortable ambient while conserving energy.

Smart Glass Applications

Bathroom windows and doors

Smart glass offers an ideal solution for bathroom windows and doors, combining style with functionality and privacy. With just a simple touch, the glass can instantly switch from clear to opaque, providing instantaneous privacy and eliminating the need for traditional window coverings or curtains. 

Kitchen Settings

In modern kitchen design, smart glass can be incorporated into your kitchen allowing you to switch between transparency for an open feel, and opacity for a sleek, clutter-free aesthetic.

Office/ meeting room walls and doors

In a professional setting, smart glass can redefine office spaces, meeting rooms, and kitchen fittings. The swift switch from transparent to non-transparent provides privacy for confidential meetings and collaborative sessions.

Dividing partitions

Perfect for open-plan living areas or workspaces, smart glass partitions bring a modern, sleek appeal with the bonus of privacy when needed. They are aesthetically pleasing and practical, enabling instant reconfiguration of your space as per your requirement.

Rear projection screen

When smart glass is in its opaque mode, it can double up as a rear projection screen, ideal for home theatres or dynamic office presentations.

Retail/ museum display windows

In retail and museum environments, smart glass can offer an interactive element that catches the attention of visitors. Its ability to interchange between transparency and opacity offers vast potential for creating engaging and innovative display windows.
