Imagine having windows that can instantly adjust their transparency, saving energy, enhancing privacy, and improving aesthetics with just a touch. Smart Glass Retrofit technology brings this futuristic concept to life, revolutionising the way we interact with our windows. In this blog, we will explore the world of Smart Glass Retrofit, its benefits, applications, installation process, cost, and more.


What is Smart Glass Retrofit?

Smart Glass Retrofit refers to the process of upgrading existing windows with smart glass technology. Smart glass, also known as switchable glass or electrochromic glass, allows the user to control the level of transparency or opacity of the glass with ease. This innovative technology utilises a variety of techniques, such as liquid crystal, suspended particle, or electrochromic technologies, to achieve this impressive functionality.

Benefits of Smart Glass Retrofit

  1. Energy Efficiency

Smart Glass Retrofit helps optimise energy consumption by reducing the need for artificial lighting and minimising heat gain or loss through windows. With its ability to control solar heat transmission, smart glass can significantly contribute to energy savings and reduce utility costs.

  1. Privacy and Security

Privacy is a fundamental aspect of any living or working space. Smart Glass Retrofit provides a convenient solution by allowing users to switch their windows from transparent to opaque instantly. This feature ensures privacy whenever needed, without compromising natural light.

  1. Aesthetics

Gone are the days of conventional window treatments. Smart Glass Retrofit offers a sleek and contemporary alternative to curtains, blinds, or shutters. With the ability to transform windows from transparent to opaque, it allows for uninterrupted views and a clean, modern aesthetic.

  1. Maintenance and Durability

Smart Glass Retrofit requires minimal maintenance compared to traditional windows. The absence of movable parts, such as blinds or shutters, reduces the chances of wear and tear. Additionally, smart glass is designed to withstand environmental factors, ensuring longevity and durability.

How Does Smart Glass Retrofit Work?

The inner workings of Smart Glass Retrofit involve advanced technologies that respond to external stimuli. Typically, an electric current or voltage is applied to the smart glass, causing molecules within the glass to rearrange and alter its light transmission properties. This allows the user to switch between transparent and opaque states effortlessly.

Applications of Smart Glass Retrofit

Smart Glass Retrofit has a wide range of applications across various industries and settings. Some notable examples include:

Residential buildings: Enhance privacy, energy efficiency, and aesthetics in homes.

Office spaces: Create dynamic meeting rooms, partition walls, or privacy glass for offices.

Healthcare facilities: Balance the need for privacy with the desire for natural light in patient rooms.

Hospitality sector: Offer guests customizable privacy options in hotel rooms or conference spaces.

Retail environments: Utilise smart glass for interactive displays or storefronts that can switch from transparent to opaque.

Factors to Consider for Smart Glass Retrofit

Before opting for Smart Glass Retrofit, certain factors should be taken into account:

Existing window condition: Ensure that the current windows are structurally sound and suitable for retrofitting.

Power supply: Determine if the existing electrical infrastructure can support the smart glass system.

Installation process: Assess the complexity and feasibility of the retrofitting process for your specific window configuration.

Compatibility with automation: If integrating with a building automation system, ensure compatibility and seamless integration.

Installation Process

The installation of Smart Glass Retrofit involves several steps. First, the existing glass is carefully removed, and the smart glass technology is precisely fitted onto the frame. Once the installation is complete, the electrical connections are established, allowing for the control of the smart glass properties. It is recommended to consult professionals experienced in smart glass retrofitting for a seamless installation process.

Cost of Smart Glass Retrofit

The cost of Smart Glass Retrofit can vary depending on several factors, including the size of the windows, the complexity of the installation, and the chosen smart glass technology. While it may require a higher initial investment compared to traditional windows, the long-term benefits and energy savings often outweigh the upfront costs.

Maintenance and Durability

Smart Glass Retrofit requires minimal maintenance. Regular cleaning with non-abrasive materials and gentle handling of the controls ensures its longevity. The durability of smart glass makes it resistant to scratches, moisture, and other environmental factors, making it a reliable choice for long-lasting window solutions.

Comparison with Other Window Solutions

When considering window solutions, it’s essential to evaluate how Smart Glass Retrofit compares to other alternatives:

Curtains or blinds: Smart Glass Retrofit eliminates the need for manual window coverings, offering a more seamless and convenient solution.

Tinted windows: Unlike tinted windows, smart glass provides adjustable transparency, allowing for greater control over privacy and light transmission.

Static privacy films: While privacy films offer a cost-effective option, they lack the dynamic functionality and sleek appearance of smart glass.

Energy Efficiency

Energy efficiency is a growing concern in today’s world. By reducing reliance on artificial lighting and effectively managing heat gain or loss, Smart Glass Retrofit contributes to overall energy savings and a greener future. The ability to control solar heat transmission helps maintain comfortable indoor temperatures and reduces the need for excessive air conditioning or heating.

Privacy and Security

Privacy is a vital aspect of any space, be it a home, office, or healthcare facility. Smart Glass Retrofit allows users to instantly switch their windows from transparent to opaque, offering a seamless transition from an open environment to a private one. This feature is particularly valuable in meeting rooms, bathrooms, or spaces where privacy is paramount.


Smart Glass Retrofit introduces a new level of aesthetics to any space. By eliminating the need for traditional window treatments, such as curtains or blinds, it creates a clean, modern look with unobstructed views. Whether it’s a residential setting or a commercial space, the sleek appearance of smart glass enhances the overall design and ambiance.

Future of Smart Glass Retrofit

As technology continues to advance, Smart Glass Retrofit is poised to become even more sophisticated and prevalent. The integration of smart glass with automation systems, voice commands, or mobile apps opens up a world of possibilities for seamless and intuitive control. With ongoing research and development, we can expect further enhancements in energy efficiency, cost-effectiveness, and durability.


Smart Glass Retrofit is a game-changer in the world of window solutions. Its ability to transform the transparency of glass, coupled with benefits like energy efficiency, privacy, and aesthetics, makes it a compelling choice for modern spaces. With proper consideration of installation, cost, and maintenance, Smart Glass Retrofit offers a promising future for those seeking to enhance their windows’ functionality and style.

Frequently asked Questions

Our privacy glass works by utilising advanced PDLC (Polymer Dispersed Liquid Crystal) film. When an electrical current is applied, the liquid crystal molecules align, allowing light to pass through, making the glass transparent. When the current is switched off, the molecules mis-align, causing the glass to turn opaque or translucent, providing privacy.
