What is a one -way window?
The one -way window is theoretically a piece of clear material, most often glass, through which you can only be seen in one direction. A common use of a one -way window would be businesses or residences that hope to maintain a certain level of privacy by blocking out of people in vision inside an office or home. The reason is the theory that if a movie is applied to the smooth glass, a one -way window still cannot block the view if there is light on the inside and is dark on the outside.
Without the use of energy, it is not possible to create a one -way window. This is because it violates the second law of thermodynamics, which states that chemical differences will tend to balance. Therefore, energy is transmitted from one side of the glass to the other. Although this is the case, the objects lit from the inside can be seen from the outside. If there is the same amount of light in both places, a one -way window is possible.
The exception of the false concept of the actual one -way window is electrical glass privacy. This glass is made of a liquid crystal layerThe film and uses energy to change the direction of light. Although in most cases this is not cost -effective for use as a one -way window, technology is used, among other things, for workshops and conference rooms. Electric glass for personal data protection can be transparent to opaque in several milliseconds. When using electrical privacy, it is important to use bulbs rather than fluorescent lamps.
If there is still a desire for a one -way window, one option is to bother glass for privacy. The most common and strictest way is to use a thin film that can be placed on a glass, allowing someone to see outside from the inside, but not the other way around. This film is now widely available in stores such as warehouses to improve home or online. There are many patterns as camouflage or stained glass.
If privacy is the most important problem of window treatment, matte glass can be considered. This type of glass still allows light transmission, but covers vision from both sides. Mirroro is often used for bidirectional mirrors, especially in police examination rooms, and one side can see, while the other side only sees the room reflection. Still, there should be some kind of light difference between them, because it will work more efficiently if it is clearer on the side.
