In Smart Glass polymer dispersed liquid crystal devices (PDLCs), liquid crystals are dissolved or dispersed into a liquid polymer followed by solidification or curing of the polymer. During the change of the polymer from a liquid to solid, the liquid crystals become incompatible with the solid polymer and form droplets throughout the solid polymer. The curing conditions affect the size of the droplets that in turn affect the final operating properties of the "smart window". Typically, the liquid mix of polymer and liquid crystals is placed between two layers of 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. This structure is in effect a capacitor.
Contacts from a UL Certified low voltage power supply are attached to the transparent electrodes. With no applied voltage, the liquid crystals are randomly arranged in the droplets, resulting in scattering of light as it passes through the smart glass window assembly. This results in the translucent, "milky white" appearance. When a voltage is applied to the electrodes, the electric field formed between the two transparent electrodes on the glass causes the liquid crystals to align, allowing light to pass through the droplets with very little scattering and resulting in a transparent state. The degree of transparency can be controlled by the applied voltage. This is possible because at lower voltages, only a few of the liquid crystals align completely in the electric field, so only a small portion of the light passes through while most of the light is scattered. As the voltage is increased, fewer liquid crystals remain out of alignment, resulting in less light being scattered. It is also possible to control the amount of light and heat passing through, when tints and special inner layers are used. It is also possible to create fire-rated and anti X-Ray versions for use in special applications. This technology has been used in interior and exterior settings for privacy control (for example conference rooms, intensive-care areas, bathroom/shower doors) and as a temporary projection screen.
Smart glass or switchable glass (also smart windows or switchable windows in these applications) is glass or glazing whose light transmission properties are altered when voltage, light or heat is applied. Generally, the Smart glass changes from translucent to transparent, changing from blocking some (or all) wavelengths of light to letting light pass through.
Our Smart glass technologies include polymer dispersed liquid crystal devices.
When installed in the envelope of buildings, smart glass creates climate adaptive building shells, with the ability to save costs for heating, air-conditioning and lighting and avoid the cost of installing and maintaining motorized light screens or blinds or curtains. Smart Glass obtains 99% UVA and UVB protection as well as a estimated 40% heat rejection.
Critical aspects of smart glass are the low consumption of electricity as well as functional features such as the speed of control, sunlight control, sound control, automation control, App control, possibilities for dimming, and the degree of transparency.
1-Does Smart Glass privacy Glass blocks harmful UV rays?
Yes, It blocks over 98% of the harmful UV rays in both its energized and un-energized state.
2-Is Smart Glass energy efficient?
Yes, Smart Glass has been considered a green product that consumes between 4 and 6 watts per meter squared.
3-Can customers install Smart Glass themselves?
Yes, we offer a complete prewired custom kit. We do recommend a installation performed by a certified contractor.
4-What is the difference between Smart Film Self Adhesive and Smart Film NON-Adhesive backings?
Smart Film Glass offers a Self Adhesive and a Non-Adhesive switchable privacy film that has the ability to contour to the curves of various types of glass. Smart Film is very popular for projection screens, electronic blinds, white boards, and high tech window treatments. Smart Glass switchable privacy Glass provides maximum clarity when energized and extreme privacy when powered off. The only difference between the two switchable films is that Self Adhesive has a peel and stick backing and or non-adhesive can be installed with a double sided adhesive clear 3m VHB tape.
