On April 12, 2011, a seminar organized by XSMedia and the Council of Experts of the Interior Design and the Architectural Environment with TVC "Expostroy" on the initiative of the editorial office of the Journal of Your Home on the initiative of the editorial office of the magazine "Ideas of Your Home" was held at the EXPOSTROY TVC conference. The discussion touched upon a wide range of problems associated with the choice and operation of translucent structures.
What are the reasons for freezing windows?
Their set. Sometimes profiles and double-glazed windows are frozen due to the fact that when mounting the window unit is placed too close to the street, that is, they are shifted to the cold part of the wall (especially often it occurs in houses with thick walls from homogeneous materials - concrete panels or bricks). In addition, condensate on the windows often appears there, where narrow profiles are installed, thin double glazing or wide window sills that prevent warm air from the heating radiator to blow the glass. In addition, it is necessary to close through holes that are not difficult to close with decorative lattices. Another reason for the freezing of the edge zone of the glass unit is a high thermal conductivity of an aluminum remote frame. To combat this phenomenon, manufacturers use a polymer framework.

Why sometimes stove windows from high-quality profiles and with double-chamber windows?
One of the main reasons for this is bad ventilation of the apartment. After installing new hermetic windows, the influx of fresh air is broken (the latter has previously received through the construct's looser). In this case, the humidity in the room can be more than 60%. The value of the dew point with a relative humidity of 70% and room temperature (about 20 s) is 14.4 C. Meanwhile, the temperature of the inner glass even the very best windows in the winter does not exceed 14 C. So, if you do not provide the regulatory air exchange, the formation of condensate is inevitable.

Nowadays, in the production of distance frames (a) and seals (b), new materials began to apply, which made it possible to improve windows characteristics.
Plastic windows covered with ecoshpon (B) - a special polymer film with a pronounced texture, is easy to adopt for made of wood.
Specialists in one voice advise not to create obstacles to the rising flow of warm air directed from the heating radiator to the window (g)
What is low-emission glass? When should it be applied to it?
In the production of low-emission windows, today is mainly used soft coatings of alternating silver layers and tin oxide or titanium. A similar solution is able to significantly reduce heat loss in winter and increase the surface temperature of the glass itself, thereby reducing the likelihood of condensate formation. Alets such a glass protects from the heat - it can lower the temperature in the room at 3-4 C. It should be noted that if using low-emission glass, the package chamber is filled with inert gas, a synergistic effect is observed and its energy efficiency is significantly increasing.
Dmitry Vlasenko
Is it true that over time inert gas "leaks" from double-glazed windows?
No, this is a myth resulting from the testing of low-quality double-glazed windows. Modern studies show that if the glass package is made in compliance with the technologies in full compliance with the GOST, for all the estimated time of operation of the product (20 years) from the chambers, no more than 10% of the gas flashes. It will also use this lower fluidity compared to air.
Dmitry Vlasenko
What is a vacuum glass? What are its properties?
While more products are rare. The essence of their design is that glass balls with a diameter of 0.5mm are placed between two glasses. They set the distance between these glasses and interfere with their "sticking". Then the air is pumped out from the chamber to give a medium close to vacuum and having excellent heat and sound insulation properties. Vacuum double-glazing includes a conventional two-chamber glass glass as a second (medium) or third (outer) glass.

Modern windows with a rotating mechanism are equipped with an erroneous action block (A), ensuring the safety of operation. To do this, serve and retractable handles of the sash control (b)
How to determine whether energy-efficient glass is established?
To do this, it is enough at the dark day to bring a light lighter to the glass light. If the glass has a low-emission coating, one of the reflections of the flame tongue will differ in color from the rest.
Albert Fogelman
How to check the tightness of the window?
Sometimes the installed window block is checked for purging, paving between the sash and the box of the paper sheet. However, today this Dedovsky method may not work, especially if the window is equipped with silicone seals or other antifriction materials. Therefore, it is best to moisten the zone of the proportion of soapy. You can also apply to seals with easily washed coloring substance, close the window, and then open and see if the trace remains on the box throughout the perimeter.
Dmitry Vlasenko
Can the glass diversify spontaneously collapse?
Yes, sometimes it happens. This usually occurs with uneven heating and cooling of different parts of the glass - the so-called thermoshock (for example, if one part of the package is in the sun, and the other in the shadow). At the same time, significant internal stresses occur in the glass, and it can give a crack. It should be borne in mind that in most cases it is easier to replace the glass in the plastic window than in a wooden one.
Svetlana Borisova
Is it true that two-chamber windows better isolate sound than one-sampler?
Due to the acoustic connection between the glasses and the occurrence of resonant phenomena in small airbags, ordinary two-chamber double-glazed windows, as a rule, provide protection against transport and aviation noise no better than single-chamber, having a similar width and a close total glass thickness.
Vyacheslav Krivovyazov
What windupacks are most effective in terms of sound insulation?
The best result can be achieved by applying glass thickness glass in the glass stack design (for example, 4 and 6mm), as well as special stamps of acoustic triplex. As for different distances between glasses in two-chamber windows, the difference in sound insulation here is rather theoretical. Yani once did not meet a reliable test report confirming this theory. However, it should be borne in mind that any soundproofing structures are effective only as long as they remain hermetic. As soon as you pick up the sash to ventilate the room, sound insulation will completely come down.
Dmitry Vlasenko
With what modern means and materials can be decorated with windows?
Recently, an original way to apply I-image images is appeared, and it is suitable for both glass and a window profile. Now it has become possible to implement a variety of window design ideas. The manufacture of stained-glass windows is actively developing using special films and phantage elements. The combination of sandblasting glass and the film creates a unique effect of playing light and color. There is an opinion that all these delights are extremely expensive. However, thanks to new technologies today they are quite accessible.
