    The principles of energy efficient glazing premises

    One of the prerequisites of comfort is optimal microclimate conditions in the room, which can be achieved using an integrated energy-efficient technologies and climate technology. One of the most effective energy-saving technologies is considered to be the correct glazing, on which depend the heat loss in the winter and keeping cool indoors in the summer.

    Incorrect glazed building is the culprit for the loss to half of the energy consumed for heating in winter and cooling in summer. As a result, to achieve the optimum air temperature in the room is not possible, and may be affected not only the health and well-being of people and home appliances. For example, according to statistics repair of refrigerators Stinol and other well-known brands, which are at the correct use for many years, it is often triggered by a violation temperature when cooling equipment used in a summer heat, and it simply can not cope with excessive stress. Proper glazing helps to normalize the heat exchange between the interior space and the environment, to protect itself from such problems.

    Before we deal with the heat leakage and penetration of heat into the building, it should understand the causes of violations of air circulation. Experts identify several reasons for heat loss through the window construction. These include: the thermal conductivity of glass, the movement of air and infrared radiation. An effective remedy is to install several heat glass - preferably of three or more. Since the second problem are struggling with mounting using sealed glass units, preventing the exchange of air from the street. Finally, for controlling the infrared radiation, which carries with it more than 70% of the heat using windows of a special low-emissivity glass with a thin metallic coating, the thickness of which controls the degree of reflection of infrared radiation and the transmitted light waves.

    The principle of low-E glass is simple, but no less than perfect. Judge for yourself: enter freely into the room shortwave solar radiation, sunlight heats objects and people, who, in turn, give this heat back into the atmosphere of the room. In addition, a considerable amount of thermal energy recovered and consumer electronics, various electrical appliances, computers, and other devices running on the network. In conventional glazing of the totality of the long-wave (infrared) radiation rushes out, and only low-emissivity glass retains heat inside is using for heating. As for the summer, in the heat of a glass works in exactly the opposite, without passing infrared rays into the room, as a result, you can save at events such as the installation of powerful air conditioners and repair of refrigerators that fail due to the fault of work in conditions of high temperature .

    There are two main types of low-E glass - solid (K-glass) and liquid (and glass). The first type of glass manufactured using the technology of the deposition of the protective layer on the hot glass. The result is a durable, resistant to mechanical damage and corrosive chemical environments material. Energy efficiency and performance of K-glass you can use it even in odnostekolnyh window systems. With regard to soft glass, then it is produced by a multilayer coating metals, nitrates and oxides. The main scope and glass - single and multi-chambered plastic windows. Soft glass less rigid, at the same time exceeds its ability to reflect on the IF-rays. The disadvantages are a limited shelf life, but these glasses can be successfully used in energy-saving systems, they are flexible in terms of changing their properties, have a high reflectivity and different democratic price. All this makes the glass and the leader of energy-efficient glazing systems of residential and industrial buildings.
