Photochromic film and glass Private Glass Photochrome
Large areas of glazing, which today have become an integral part of modern architecture, require effective solutions to the problem of their shading.
The heat transfer resistance of window structures and the ability of glass to act as an obstacle to solar radiation are the areas that are most exciting for developers of new window technologies today. Research in these areas is carried out all over the world, and everywhere they rely on modern ultra-efficient technologies.
The main direction in these developments is the control of the intensity of transmission of solar radiation by glass. This control is active and passive.
Passive effects of this control are inherent in photochromic and thermochromic glass, and active effects are realized in the so-called “smart” glass.
Photochromic glasses change their optical properties under the influence of sunlight. This property of glass is due to the effect of photochromism. Due to the composition of the glass, under the influence of sunlight in it, reactions that cause changes in the throughput of the glass occur reversibly (that is, with the possibility of returning to their original state).
Photochromic glass as a part of smart double-glazed windows.
What practical value, in the context of the idea of a modern house, do photochromic glasses have? First of all, they make the room in the houses more comfortable - depending on the lighting on the street, they will change their light transmittance, providing optimal lighting in the room. From the designers' point of view, photochromic glasses are also irreplaceable - ordinary curtains and blinds are not relevant now, and if you have panoramic windows in your house, using such items will be even difficult. In this case, in order to control the level of penetration of sunlight from the street, photochromic glasses are ideal. Such glasses can be part of a double-glazed window with smart glass and then the functionality of such a double-glazed window is significantly expanded. In addition to dimming when exposed to sunlight, instant privacy is possible. At the touch of a button, you ensure complete privacy, as smart glass becomes completely opaque matte.
I would like to note that in addition to using these glasses in private homes, they are quite widely used for glazing office buildings with panoramic stained-glass windows.
It allows you to automatically adjust the illumination in rooms where panoramic glazing is used. Obviously, photochromic glass has a huge advantage over conventional energy-saving tinted glass. The latter cannot be enlightened when, for example, it is cloudy on the street. In addition, tinted windows remain dark in the morning and evening, i.e. when their tinting only interferes. The fact is that natural lighting is the best for the eyes, and why waste energy if there is free and also useful light.
Together with the level of illumination, photochromic glass also regulates the flow of heat along with the sun's rays. The darker it becomes, the less heat penetrates the room.
PHOTOCHROME GLASS PROPERTIES
• Changes optical properties under the influence of sunshine and heat
• The more sunlight, the darker the glass becomes and the less heat penetrates the room
• The effect of photochromism is reversible, that is, glass returns to its original state
ADVANTAGES
• Does not require additional power supplies, controller connection
• Due to their light transmittance, they provide optimal lighting in the room, as well as thermal comfort
• Serves as a barrier to solar radiation, 99% protection against UV radiation
• Ability to use in buildings with panoramic glazing, and where the use of curtains and blinds is impossible
• Saves on air conditioning in the summer
• Easy installation
