Plastic Windows Thermal insulation Thermal insulation - one of the main functions of the window. Heat loss can be divided into three kinds: loss-which flows from the hot air evaporate through the walls, ceiling, floor, doors, windows - the so-called transmission and ventilation or convection losses, which are defined as the amount of heat required to heat up to room temperature cold air coming through the cracks in windows, doors, and the system ventilation, heat loss by radiation - are made by converting the energy of thermal motion of particles in the radiation energy, which is concentrated mainly in the infrared spectrum (SF6) As usual glass window in this spectrum is almost transparent, so the heat loss through radiation is veliki.Cherez window disappears much more heat (see picture), than through the exterior wall, roof or floor, so the heat shield - this is one of the main functions of a window which provides comfortable conditions indoors. Of course, very important to the external climatic conditions. It is clear that the windows, which are suitable for glass house in Sochi, is unlikely to arrange the inhabitants of Vorkuta. Therefore, choosing a window, you need to pay attention to the parameters of the thermal protection due to climatic conditions, which will be used by the window. Ventilation Thermal insulation - one of the main functions of the window. Delivering the best performance insulation, advanced windows sealed disrupt the natural ventilation. The easiest way to provide access to fresh air through the window - is to lift it. Special fittings sets open doors in one of the following provisions: tightly closed completely open ajar on top 10-15 cm - the so-called summer ventilation flap ajar on top of 3-5 mm, and all around between the pads and the profile has a small gap for air...

Contract Area Boundaries In granting the right of subsoil use contract area boundaries (block) and the deposit may be in different ratios: 1) within the geological / mining lease is one or more fields, whose boundaries are entirely within the boundaries of the geological / mining lease, and 2) within the geological / mining lease is one or more fields whose boundaries extend beyond Contract Area in the free subsoil, and 3) within the geological / mining lease is one or more fields whose boundaries extend beyond the contract area for territories occupied by neighboring (other) mining companies. The first and second cases do not represent the subsoil for any complications, because in the former case, the problem with the boundaries it is not necessary at all, and in, the second the question of expanding the boundaries of the contract area is decided by the competent authority without competition. In the third case, it all depends on the circumstances, because the law, although it defines the general principles solve the problem, but ignores the important and significant issues connected with it. By the way, the definition of the term "deposit" given in the Law "On Subsoil and Subsoil Use" also does not eliminate the uncertainty in the whether the accumulation of mineral deposits located on the adjacent territories of contracting one or two different mine fields. So, what are the main principles of solving problems where the boundaries deposits extend beyond the contract territory occupied by another user of mineral resources? These principles are fully presented in an article 90 of the Law "On Subsoil and Subsoil Use". Cite this article in full: "1. In the case if part of the field, where the subsoil user carries out operations for the exploration or extraction, is located within the territory of another contract of...
