Today, the construction industry is at a very high stage of development. Technologists always come up with new materials or improve old ones. For example, a relatively new material is multifunctional glass.
What is a product?
This is a special material that is obtained by applying a special soft metal spraying on ordinary glass. Such a coating is a kind of filter. That is, multifunctional glass is capable of transmitting the necessary, only the required waves present in the composition of solar radiation.
The production of such material is associated with certain technical difficulties and is time-consuming. Therefore, such a glass, the price of which is quite high, not everyone can afford.
It is produced by means of a deep-vacuum magnetron process. In appearance, the product is practically no different from ordinary window glass. However, the main difference is the greenish or bluish color of the surface. The technical advantage of the material is that it bends, which means that it can be used to decorate a variety of interiors, windows of various sizes and shapes.
Material benefits
So, multifunctional glass has the following advantages:
- In the summer, housing is reliably protected from overheating.
- In winter, the heat does not leave the room.
- Despite the fact that a special coating is applied to the glass surface, the natural lighting of the rooms does not get worse. That is, the cost of electricity is reduced.
- High strength and resistance to scratches, other mechanical damage.
- Thanks to the mirror effect, multifunctional glass significantly reduces the ability to view rooms from the street.
- Such material can be subjected to additional processing: hardening, cutting, lamination, heating.
- Due to the fact that some types of ultraviolet rays enter the room, this makes it possible to reduce the concentration of pathogens in it. There is a kind of disinfection of rooms.
- The slightest likelihood of condensation is eliminated both on the glass surface and inside the glass packet.
- Do not worry about the interior if it uses a lot of bright colors. Multifunctional material reliably protects them from fading.
- The presented double-glazed window provides additional sound insulation.
The principle of operation of the product
The principle of operation of multi-glass is quite simple. In the summer, spraying “sorts” the infrared rays, which avoids overheating of the living room. Therefore, even on a very hot day in the room, the atmosphere remains comfortable. Thanks to the metallized layer, more than 55% of the thermal energy is screened out and does not enter the room.
In winter, the product behaves differently. It works as energy saving. Spraying is capable of reflecting long waves of thermal radiation coming from heating devices back into the room without absorbing them and without releasing them outside. Heat loss is reduced by more than 20%.
Specifications
Presented glass, the price of which is 11,000 rubles. and more, depending on size, has the following technical parameters:
- The coefficient of resistance to thermal return is 0.73 degrees * m2 / W.
- Light transmittance - 62%.
- The heat preservation in the room is 73%.
- The noise isolation level is 31 dB.
- The total transmission energy is 40%.
- Glass unit thickness - 24-40 mm.
Glass properties
So, multifunctional glass, the characteristics were listed above, has some very useful properties:
- Maximum energy conservation. At the same time, the luminous throughput remains at a high level. This provides excellent selective sputtering capability. That is, no matter what the thickness of the glass unit, the product is able to transmit the rays of the sun only such a length that is necessary to ensure comfort in the room. The remaining mass of radiation does not pass the spray barrier and is reflected. Light enters the rooms unhindered.
- Excellent thermal insulation. Maximum quality is achieved if the glass unit contains ordinary and multifunctional glass.
- Large selection of colors.
Application area
So, the presented products are used quite widely:
- For the arrangement of residential premises in private houses and apartments.
- During the construction of attics, winter gardens.
- With success, such windows are also used in office buildings, as they provide maximum comfort to workers.
- It is possible to use multifunction glasses even in cars.
The presented material not only has an extended service life, but also provides a soft light that does not blind the eyes.
Product Device
The presented glass for double-glazed windows has already gained popularity in our country, as it has good quality and a high level of efficiency. This is ensured by the fact that the product consists of several layers:
- Extreme . Their main task is to adjust the light transmission. In addition, they control the level of specularity of the glass. The color of the spraying is also regulated by these layers. In their composition they have nitrides, as well as oxides.
- Functional . It is he who is the main one. Its task is to transmit rays of the required length and reflect the rest of the radiation. It contains chrome and silver.
- Protective . It is necessary to prevent any chemical or mechanical damage to the functional layer. In addition, it is able to partially absorb and reflect thermal short-wave radiation.
It should be noted that all the layers presented are applied crosswise. This makes it possible to increase the strength of the spraying and its quality. In addition, the coated side is inside a hermetically sealed double-glazed window, so its service life is significantly increased.
Product Selection Features
In order for the house to always be comfortable, regardless of whether it is winter outside the window or summer, it is necessary to choose the right double-glazed windows for windows. For this, it is advisable to take into account such recommendations:
- An important parameter is the thickness of the glass. Not only properties such as thermal and sound insulation depend on this, but also the weight of the entire product. Therefore, here you need to take into account the thickness of the walls, as well as the material of which they are built.
- Do not trust the first store you get. It is better to buy a window from a trusted seller who has all the technical specifications of the product and quality certificates.
- It is also necessary to pay attention to additional functions: different ventilation modes and others.
- Do not forget about the cost of a double-glazed window. Its minimum cost is about 10-11 thousand rubles. Naturally, it all depends on how many ordinary glasses were used in the manufacture of a double-glazed window along with multifunctional ones.
Naturally, you also need to decide for which room you need a window, which heating system is installed. In any case, the advantages of multi-function glass are obvious. Good luck
