PRIVA-LITE Switchable Glass – Privacy On Demand!


The open layout workplaces have indeed managed to secure a top spot in the business owners’ minds when it comes to a flexible and economical workplace. But each company’s needs vary, and for some, office partitioning may be required to achieve desired privacy prerequisites. Even in open form offices, the manager might feel the need to discuss an important strategy with the team leader in privacy.


Thanks to innovation in the glass industry, now we have extremely versatile PRIVA-LITE switchable glass that can create privacy with just a flick of a switch, no matter the type of work setting. You can now have an “honest and transparent” feel of open-form office one second and the complete confidentiality and privacy the next!


PRIVA-LITE switchable glass, otherwise known as a smart or intelligent glass system, blends the power of both heat transmission and transparency, delivering you a flawless experience every time. Long gone are the days when you had to use curtains, blinds or shades to gain the privacy you needed.


With PRIVA-LITE glass technology, you can effortlessly switch from opaque to a transparent mode or vice versa, with a simple switch, at your discretion. Many organizations, especially health-care institutions, convention centers and universities have already installed PRIVA-LITE glass in their settings, witnessing excellent results that are worth more than the investment. Have you decided yet?


How Does PRIVA-LITE Switchable Glass Work?


It’s a category of active glass that leverages the Liquid Crystal (LC) technology to deliver instant privacy through a power switch. The glass pane is coated with a Liquid Crystal film, and under normal circumstance (without any power supply), the crystal molecules are randomly distributed to create a translucent, frosted effect which still allows the light to get through while ensuring privacy. When this liquid crystal film receives power, the molecules re-orient and line up automatically, giving the glass a completely transparent appearance.


Flexible Application Areas of PRIVA-LITE Switchable Glass


The versatile characteristic of PRIVA-LITE enables it to be used in myriad ways, for example, incorporating it into fire-rated glazing, lead-lined for MRI and x-ray control rooms, double glazing or any other area where you intend to install glass – with no maintenance at all. The switchable glass can be sandblasted, silk screened or curved, and can even be put into use as rear or front projection screens on account of its high resolution. A huge variety in terms of size and configuration assures that you’ll find a panel that goes well together with your particular requirements.


The PRIVA-LITE glass is built to be installed on the inner side of a building and as stated earlier, it gives a whole bunch of customization choices. For high privacy applications such as toilet doors, the state-of-the-art glass system enables the use of 2 LC films on a triple laminate panel. For hanging projection screens, the panels are meticulously polished on 4 edges, with 2 holes drilled for the purpose of hanging. The glass thickness and composition, on the top of the heat strengthening feature, enable one to enjoy PowerPoint presentations, videos or other analyses on the projector screen. Some other application areas are windows and skylights, conference rooms, walls etc.


When it comes to finding the desired shape in PRIVA-LITE glass, you’ll find almost all shapes in panels with one linear edge. The circular shape can be achieved by using 2 LC films side by side with the electrodes on the diameter.

Advantages of PRIVA-LITE Switchable Glass

Beyond the ease of operation and privacy benefits, PRIVA-LITE does away with the need to manually draw curtains or blinds in your facility that might need regular cleaning. Here are some more advantages:

  • Creates a Modern Look: PRIVA-LITE glass will definitely breathe a new life into your facility’s aesthetic appearance due to its amazing ability to blend easily with the existing design. Regardless of the type of environment, with just a simple flick of the switch, this glass will effortlessly adapt and respond to the needs of facility occupants. With multi-functional glass windows and walls flaunting your workspace, the visual appeal of your facility is set to rise higher.

  • Improves Security and Safety: Having been tested to comply with CENELEC European standards, PRIVA-LITE will block out the prying eyes and enhance the security and safety aspects of your building. To elevate the safety to the next level, the glass can be made to incorporate fire-resistant and bullet-resistant glazing. This will help safeguard the facility from potential threats such as fire, smoke, flames and security breaches.

  • Enhanced Temperature Regulation: Through the inclusion of Low-E glass, PRIVA-LITE smart glass is able to allow or block the heat-bearing sunlight. So, when it’s hot outside, the glass lets in the light only whilst blocking the heat, thus helping to keep the office environment conducive.

Fire Resistant Glazing Systems: Prevent the Transfer of Fire, Radiant Heat and Smoke

City planners, architects, and builders greatly benefit when they use an innovative and durable fire-resistant glazing system within their commercial spaces. This reaps several benefits, not the least of which is staying compliant with new federal fire safety code requirements. Fire, smoke and radiant heat transfer protection precautions are life-saving aspects in modern architecture.


The Growing Urgency for Fire Resistant Glazing Systems in 2020

In the U.S. alone, fire-related deaths have significantly increased since the 1970s, with over $23 billion in dollar losses were incurred as a result of structural fires in 2017. New figures reveal that at least one fire department in the nation has to respond to a fire every 24 seconds.

Apart from the immense damage wreaked by the fire and smoke to the structural core of the building and its contents, a majority of casualties occur due to inhalation of the byproducts of combustion from a structural fire.


How Fire Resistant Glass Works

This is why fire-resistant glazing systems have become a centrepiece in architectural plans. They protect people, property, and tap into several multi-functional aspects such as enhancing the visual appeal of the structure. Unlike fire-protective glass, these systems do not only prevent the spread of smoke and fire, but they also act as a heat-barrier, in that they prevent radiant and conductive heat from transferring from room to room.

Essentially, the fire, smoke, and radiant heat do not reach the items on the protected side of the glazing system, thus preventing their combustion. Auto-ignition can occur if temperatures rise above the flashpoint. Items in an adjacent room can spontaneously combust without a pilot flame.

Fire-resistant glass is a laminated assembly; one that has several layers of glass separated by heat resistant interlayers. It must be incorporated by architects, especially when the building safety code demands an assembly of this nature. This usually goes hand in hand with stipulations dictating that the temperature rise on the protected side should go no higher than 250 degrees Fahrenheit.


Optimize Fire Performance With Cutting-Edge Glazing Systems

At Greenlite Glass Systems, our fire-resistant glazing solutions are fully tested for their mechanic stability and approved for immediate use.

These protection levels are defined as per specific time durations as follows: 45, 60, 90, 120 and 180 minutes. Aside from the standard levels, the systems can be engineered to have custom protection levels should the architect so wish. Fire-resistant glazing applications are incorporated into partitions, doors, decking, windows, stairwells, and walkable skylights to optimize their fire performance.

Besides safety, these glazing systems focus on “open” concepts, in that they allow plenty of natural lighting to penetrate into the facility, creating a warm, vibrant and comfortable atmosphere.

Below, we’ve compiled a list of the most effective glazing applications that meet local construction and fire safety norms.



CONTRAFLAM Structure is a revolutionary fire protective and resistive butt-glazed solution that also displays impressive fire-resistant properties for up to 120 minutes. Its architectural appeal is another aspect that boosts this assembly’s popularity in architectural circles, given that CONTRAFLAM Structure resembles an uninterrupted floor to a ceiling glass wall with subtle silicone joints.

Safety is ushered to the forefront without compromising on the system’s ability to allow plenty of daylight to enter the building, creating a fresh environment. CONTRAFLAM Structure has been comprehensively tested to perform even in the face of high impact resistance and live loads. Contraflam has both EPS and HPD certificates for sustainability.



CONTRAFLAM, a tempered safety glass assembly, provides fire resistance for 60 to 180 minutes. The wireless assembly holds an environmentally-friendly chemical mixture that fills the glass chambers in the event of a fire. Contraflam has both EPS and HPD certificates for sustainability. This clear system allows for uninterrupted vision into fire-affected zones so that occupants can map out a safe route of escape.

CONTRAFLAM serves its purpose well as an interior radiant heat barrier and an exterior fire-resistant system. The application is great for those locations such as accidental human impact safety-rated zones. 



LITEFLAM is Greenlite Glass Systems’ proprietary fire-rated glass system with immense load-bearing capacities. The assembly has a certified test-listed fire rating from 1 to 2 hours. It has been deemed as the only exterior glazed system and Insulated Glass assembly in North America capable of doing so.

Architects and builders reach for this novel solution, owing to the fact that it is modular and allows for design flexibility. Additionally, LITEFLAM allows architects to request decorative colour frits and sandblasted glass without compromising on its fire rating properties.

Aside from its durability, LITEFLAM offers moisture– and slip-resistant surface and comes with a standard live loading capacity of 100 psf – but can be designed to withstand higher loads if required.

With a slim 3.5” profile, LITEFLAM is comprised of CONTRAFLAM intumescent glass, which is laminated and tempered glass. Solar control coatings are available for added solar control. Because the assembly is essentially composed of individual glass panels, the repair is possible without pulling apart the entire system. A sacrificial sheet is also an option that allows for only the top light to be replaced rather than the entire IGU unit.

It offers excellent protection against conductive and radiant transfer of heat as well as acts as a barrier to smoke and fire.


VDS Fire Frame Assembly

The VDS curtain assembly includes partitions, doors, walls and window frames. It can be paired with fire-rated glazing applications to further enhance fire-resistive properties.

VDS is structurally sound and has a clean and streamlined look. The system offers total design creativity, and when used with CONTRAFLAM, can act as a fire-resistive heat barrier for periods of one hour and above.



The VDS CURTAIN WALL is an advanced fire-rated steel curtain that is incorporated in doors, windows, partitions, etc. Like its predecessor, it offers fire-resistive properties when used in tandem with fire-rated glazing products. For exterior applications, this system acts as a barrier to radiant heat for 60 to 120 minutes.

Are Walkable Glass Skylights Strong Enough To Hold Their Own in Rough Weather?

Walkable skylights are a wonderful rooftop and decking application to enhance the appeal of your commercial facility or institution. They bring life to your architectural design vision. If you’re in the market for a glass skylight but secretly worry about its ability to withstand harsh American climates – whether they be high winds, hail, snowstorms, intense heat, and the likes – we’re here to placate your fears!

While walkable skylight suppliers are plenty, there is just a handful in the U.S. market that offers quality solutions configured to your custom specifications. Greenlite Glass Systems is committed to providing innovative solutions that truly go the distance!

LITEFLAM is Greenlite’s patented fire-rated glass application and the very first exterior fire-rated walkable skylight system. Because this system is designed to allow natural daylight to flood through your commercial facility, you can SAVE tremendously on your monthly energy bill.

Whether you install this application on the roof or in subterranean levels in the facility, you won’t have to depend on artificial lighting to create a well-lit environment. Not only will your occupants enjoy a vibrant and productive atmosphere within which to function, but you can drastically reduce your carbon footprint by not relying on artificial light sources.

While that’s all well and good, you might be concerned about the skylight’s ability to maintain its integrity in harsh and inclement weather conditions. Below we explain how LITEFLAM is expertly engineered to resist deterioration even in the face of the most gruelling elements!


Extremely Sturdy and Fire Resistant

LITEFLAM uses advanced technology to perform even in the most demanding environments. It is a fire-rated glass flooring application and serves as a firestop to prevent the transfer of smoke, radiant heat, and flames from penetrating into your facility by compartmentalizing the interior spaces.

LITEFLAM’s superior durability allows it to withstand all weather conditions like snow loads, hail, harsh sunlight, and rain. The walkable skylight system has been proven in over 100 projects around the world to be fire-resistant for 1-2 hours – making it one of the best choices for exterior glazed systems for Insulated Glass assembly in North America.


Impressive Load-Bearing Capacity

LITEFLAM has been tested extensively to ensure that it can take rigorous internal and external pressures. This walkable skylight application meets federal safety codes and structural design standards, thus achieving both safety and redundancy. LITEFLAM adheres to all IBC (International Building Codes) requirements including ballistic impact ratings as well as thermal and live load codes.

We configure to your customized expectations. While LITEFLAM has a deceptively slim profile (3.5” thickness), you can have the glass designed to take loads that exceed the standard 100 pounds per square foot (psf). The ability to take on such impacts lends it amazing survivability rates. During heavy hail storms or when snow accumulates on the skylight, you won’t need to worry about LITEFLAM giving way, cracking or shattering. It is sturdier than its traditional flooring counterparts.

Because of minimal repair and maintenance costs, you can save on cost over the life cycle of the building. And when repair or maintenance is called for, you can remove only those individual panels that need attention rather than dismantling the entire assembly. There is an optional sacrificial sheet that allows the owner to replace the top light and not the entire unit.


Non-Slip Surface Resists Moisture

There is a misconception that glass flooring applications, in particular, are slippery and not at all suited for high volumes of foot traffic. LITEFLAM is designed to be water- and moisture-resistant. You can opt to have a non-slip Frit (patterns or dots) surface. The Frit is a baked-on ceramic that will endure over time. This prevents hazards during a rainy day or even if there is an accidental spill within the facility. Because of LITEFLAM’s wide scope of operability, this novel flooring system is being used in commercial enterprises more and more around the USA.


Suitable for Coastal and Non-Coastal Applications

LITEFLAM can tackle both coastal and non-coastal applications with ease. Especially around coastal regions, corrosive elements tend to wreak havoc on constructional components. LITEFLAM is able to resist pressures, high winds and drastic temperature fluctuations. This non-corrosive system keeps your interiors and the possessions within them well protected from anything the weather might have in store.


Regulates Indoor Temperatures All Year Round

LITEFLAM offers solar coating options to contribute to overall solar control. Whether your facility witnesses heavy wind, rain or snow, the interiors remain cool in the summer and warm during the brutal winter months. It seals in indoor temperatures, ensuring that you do not have to spend exorbitant sums every month due to poor insulation or leakage of conditioned air.
