Benefits of Switchable Glass

Privacy Control

It provides instant privacy when needed. A simple switch or button tap transforms transparent glass into an opaque shield.

Energy Efficiency

Switchable glass helps reduce energy costs by controlling the amount of sunlight entering a space. By dimming the glass on sunny days, it reduces the need for air conditioning and artificial lighting.

UV Protection

Many switchable glass products protect furniture and artwork from harmful ultraviolet rays. This is particularly critical in museums and galleries.

Aesthetics

It enhances the aesthetics of any space, creating a modern, sleek, and minimalistic look, making it a preferred choice for contemporary interior designs.

Security

In security applications, it can be used to add an extra layer of security by preventing outsiders from seeing inside when in opaque mode.

Durability

Switchable glass is durable and easy to maintain, making it suitable for various applications.

Application of Switchable Glass

Residential Spaces

Switchable glass can be used in bathrooms, bedrooms, and living areas to provide privacy without the need for curtains or blinds.

Commercial Buildings

Offices, conference rooms, and storefronts can benefit from switchable glass, offering privacy for meetings and presentations while maintaining an open atmosphere.

Healthcare Facilities

Hospitals and clinics often utilise switchable glass in patient rooms, operating theatres, and consultation areas to balance privacy and visibility.

Hospitality Industry

Hotels and restaurants can utilise switchable glass for private dining areas, partition walls, and bathrooms, enhancing the guest experience.

Retail Environments

Switchable glass can be integrated into shopfronts and display cases, adding a modern touch while providing flexibility for visual merchandising.

Switchable Glass Production Process

Switchable smart glass is a highly engineered product that involves advanced manufacturing techniques. The process of making switchable smart glass typically involves the following steps:

Coating: A thin layer of indium tin oxide (ITO) is coated onto a glass substrate. This coating acts as an electrode and allows for the application of an electric field to the glass.

Lamination: Two or more glass sheets are laminated together with a liquid crystal film in between. The liquid crystal film is made up of tiny liquid crystal droplets that are evenly dispersed throughout a polymer matrix.

Alignment: The liquid crystal droplets are aligned in a specific direction using a strong magnetic field. This alignment is critical to the performance of the switchable smart glass.

Encapsulation: The laminated glass is then encapsulated in a vacuum-sealed chamber, where a special polymer material is used to fill the space between the glass sheets.

Wiring: Electrical wires are attached to the electrodes on the glass to allow for the application of an electric field.

Switchable Glass Installation Requirements

Surface cleaning: Before starting the installation, ensure that the surface where the switchable glass will be installed is clean, dry, and free from any dust or debris.

Measuring: Accurate measurements are essential to ensure a perfect fit. Measure the dimensions of the window or desired area where the switchable glass will be installed.

Avoid Sharp Objects: Be cautious when handling objects near switchable glass to prevent scratching or damaging the surface. Use gentle cleaning tools and avoid sharp-edged items.

Electrical Safety: If any electrical maintenance or repairs are required, ensure that the power supply is switched off and consult a qualified electrician.

Testing and Calibration: Once the wiring is complete, the switchable glass system undergoes testing and calibration to ensure smooth operation. This involves checking the functionality of the glass, verifying the response time between states, and ensuring proper synchronisation with control devices.

Switchable Glass Technologies

The two most common technologies used in switchable glass are Polymer Dispersed Liquid Crystal (PDLC) and Suspended Particle Device (SPD).

PDLC Technology

Involves liquid crystal molecules dispersed in a polymer matrix. When an electric current is applied, the liquid crystals align, making the glass clear. Without current, the crystals scatter light, making the glass opaque.

SPD Technology

Utilizes microscopic particles suspended in a liquid. When voltage is applied, the particles align to allow light to pass through, making the glass clear. In the absence of voltage, the particles are randomly oriented, blocking light and making the glass dark.

FAQ

Q: Can switchable glass be used instead of curtains and blinds?

A: Switchable glass has been used as a more modern replacement for blinds and curtains, offering a quick fix for harsh glare and direct sunlight without plunging the room into darkness.

Q: How does switchable glass work?

A: The functionality of switchable glass relies on polymer-dispersed liquid crystal (PDLC) technology. By applying an electrical current, the embedded liquid crystal molecules respond, altering their orientation. This orientation allows the light to pass through, causing the glass to appear clear. Upon turning off the current, the molecules then relax to a scattered state, which disrupts the path of light, making the glass appear opaque.

Q: Can switchable glass be made fire resistant?

A: Fire safety solutions are regularly becoming a requirement in most commercial spaces, we manufacture fire-resistant switchable smart glass, giving you all the benefits of smart glass plus an added layer of safety.

Q: How do you clean switchable glass?

A: In switchable glass products where the PDLC layer is sandwiched between 2 or more panels, you clean the glass in the same way you would clean any glass surface. For Switchable Film Products where the PDLC film is exposed, we only recommend using IPA wipes to clean the surface as using water or cleaning liquids could damage the film.

Q: Is switchable glass worth it?

A: You may find switchable glass to be a bit expensive, but considering the technology incorporated in them, the price range is understandable. However, if you add up the costs of cleaning and energy costs across its lifetime along with its other benefits it is actually a very cost-effective product.

Q: What is switchable glass made of?

A: Typically, the liquid mix of polymer and liquid crystals is placed between two layers of glass or plastic that include a thin layer of a transparent, conductive material followed by curing of the polymer, thereby forming the basic sandwich structure of the smart window.
