Switchable smart film has quickly become a go-to solution for modern spaces, offering privacy, energy efficiency, and sleek design. However, like any technology, it comes with its own set of considerations. Here are the key details you should know about switchable smart film before incorporating it into your space.
We are sharing with you some things that most Smart glass manufacturers won’t.
1. Haze
Smart Glass and Smart Film go to clear to opaque in a flick of a switch providing privacy on demand however when the glass is switched to clear there can be a slight haze. This can not be avoided due to the presence of small droplets that reflect the light, although there are ways to minimize it.
Vishnupriyam has the lowest haze level (2.6%) on the market today, however, under certain light conditions, the glass will reflect. This will sometimes be more obvious when the glass is viewed from an angle.
When positioned at a direct angle you will get the highest level of transparency and the lowest level of haze. As the viewing angle becomes wider, the level of haze increases. This phenomenon is known as Wide Angle Scattering, which causes haze due to the loss of transmissive contrast, and Narrow-Angle Scattering which reduces clarity.
2. Lighting Conditions
The effectiveness of switchable smart film can be influenced by lighting conditions. In bright environments or direct sunlight, the opacity of the film might not be as pronounced, and the haze effect could be more noticeable. Consider the lighting in the area where the film will be installed, as it can impact its functionality and overall appearance.
With high-quality products, this haze will barely be noticeable if this slight haze is a concern we can make recommendations on how to diminish it.
3. Smart Film Is Designed for Indoor Use Only
While switchable smart film is an excellent solution for both commercial and residential spaces, it is specifically designed for indoor applications. The film is not made to withstand the harsh conditions of outdoor environments. Prolonged exposure to the elements—especially UV rays, extreme temperatures, or moisture—can degrade the film’s structure and functionality. For example, UV rays can cause yellowing over time, which can affect both its appearance and its performance. If you’re considering installing switchable smart film in an outdoor setting, such as on a patio or exterior windows, you may want to reconsider or look for a version specifically designed for exterior use.
4. Silicone
Silicone is an important material used in the production of switchable smart film. It serves as the bonding agent that keeps the layers of the film together while providing flexibility and durability. Silicone also helps maintain the film’s functionality by ensuring that it remains stable and effective throughout its lifespan. However, it’s important to ensure that the silicone used in the smart film is of high quality. Poor-quality silicone could lead to issues like delamination. Where the layers of the film start to peel away, reducing its overall effectiveness and lifespan.
5. Busbars
Busbars are conductive elements embedded in switchable smart film that allow the film to switch between transparent and opaque states. These elements are responsible for distributing the electric current evenly across the surface of the film. If the busbars are misaligned during installation, it could lead to uneven performance With certain areas of the film not transitioning properly. To ensure optimal functionality, it is crucial that the busbars are installed correctly. And that the film is applied by professionals who understand how to handle these delicate components.
If requested Vishnupriyam Film without leads attached, begin by carefully soldering the electrical cables to the copper busbars.
NOTE: Special “Anchor” is installed on each busbar. DO NOT SOLDER TO “ANCHOR”
6. Yellowing
One common issue with switchable smart film is yellowing, which can occur over time, particularly if the film is exposed to direct sunlight or UV radiation. Yellowing is a result of UV degradation, and while it doesn’t necessarily affect the film’s ability to switch between states. It can significantly impact its appearance. As the film ages, the yellowing effect may become more pronounced. Which can be unsightly and diminish the sleek, modern aesthetic that smart films offer. To minimize yellowing, it’s important to install switchable smart film in areas with minimal direct sunlight or to choose films with UV-protective coatings. However, high-quality PDLC films like Vishnupriyam, have an additional UV protective layer. Vishnupriyam Film will not yellow with the sun, and will always look clear.
7. Delamination
Delamination occurs when the layers of the switchable smart film begin to separate or peel away from each other. This is often caused by poor installation, prolonged exposure to harsh conditions, or physical damage to the film. Delamination can severely affect the film’s ability to switch between clear and opaque, and it may also cause permanent visual imperfections. Proper installation is key to preventing delamination, as is choosing high-quality smart film that has been designed for long-term durability. Additionally, regular maintenance and careful handling can help preserve the film’s structural integrity.
A high-quality film like Vishnupriyam will have a strong PDLC glue that keeps the layers of the film stuck together.
8. Smart Film can be scratched
While switchable smart film is generally durable, it is not immune to scratches. The surface of the film is relatively delicate, and any sharp object or abrasive material could leave permanent marks. Scratches on the surface of the film can affect both its functionality and appearance, potentially causing irregular switching between transparent and opaque states. To prevent scratching, it’s essential to handle the film carefully during installation and cleaning. Use non-abrasive cleaning materials and avoid using sharp tools near the surface of the film.
