There are many kinds of window films available in the market for different functions. These functions include: solar heat reduction, UV protection, glare reduction, privacy, security, energy savings as well as switchable film and film that can be used as a projection screen.
Since only one layer of film can be applied on a window, we may utilize only one or a few of aforementioned functions. For years, it’s been a dream to have a window film that offers many different functions. Now this dream becomes true with cutting-edge 3G Switchable Film from InSync Smart Glass.
As we know, ultraviolet rays are harmful to interiors. Three types of window films in the market are used to block UV and infrared light. They are dye- and pigment containing window film, metallic coating window film and ceramic coating window film. Dye and pigment type is dark film has an absorptive function to block UV and infrared, but it also blocks over 90% of useful visible light and results in discoloration. If this type of film is applied on the inside of a window, it cannot save much energy, because absorbed heat on the window still needs air-conditioning power to cool down the room. Also blocking visible light may increase the use of artificial lighting.
InSync Smart Glass uses non-linear technology and nanotechnology to block UV and infrared while allowing full spectrum of visible light to transmit. Full natural light without discoloration not only meets human’s comfortable levels, but also allows indoor plants to grow normally.
Metallic coating window film is able to reflect all wavelengths of sunlight. It usually has mirror like appearance. The reflection has no selectivity. When blocking 60% of infrared, it also blocks over 80% of visible light. This film does not allow seeing through from bright side to dark side. It may provide privacy at day time from inside. However, this function can be problematic at night for home security, when outside people can see inside, while people inside cannot see outside.
Some governments and communities restrict use of windows films with strong mirror reflection. Some people do not feel comfortable being surrounded with mirrors in home at night. InSync Smart Glass can be switched between clear and opaque.
In any light condition, vision ability is equal in both sides. Privacy function is totally controlled by user.
Like ceramic type of window film, InSync Smart Glass consists of nanometer-sized coating. With a non-linear optic system and silicone- and fluorine-containing polymers, it is capable to make light travel in a curved way inside of the film and selectively control nature light to pass, with UV and infrared to reflect. InSync Smart Glass can block 100% of UV and 70% of sun’s infrared ray, while allowing most nature light to pass.
To reduce building energy consumption, we have to emphasize overall efficiency and controllability, because energy saving is not depended in one situation. Sometime, our effort for saving energy in one situation is draw backed by other situation.
For example, absorptive or reflective window films block over 80% natural light while blocking infrared, causing more energy consumptions due to artificial lighting. However, diffused light from InSync Smart Glass can reduce the use of artificial lighting.
A reflective window film may reject sun’s heat gain in summer, but it will also block sun heat in winter and then cause more energy consumption from heating. InSync Smart Glass can efficiently handle both situations with its switching capability. It may reject summer sunlight heat in scattering mode and allow sunlight heat to admit in winter in clear mode.
3G Switchable Film has best functions in projection and privacy. Projected images can be seen from both sides at any angle.
InSync Smart Glass has the strength of bullet-proof glass. For similar purposes, InSync Smart Glass has widely been used in many places, including entirely covered cruise ships in United Arab Emirates, many high speed trains in China and Germany, airplanes in US and France and countless number of cars and recreation vehicles everywhere in the world and 24 major airports in China.
