The design of the double-glazed window and the purpose of the constituent elements The double-glazed window, as a window structure, appeared quite a long time ago, almost 90 years ago. It has become a worthy replacement for double windows, simplifying their arrangement and retaining the main properties. Their technical essence is simple - two sheets of glass, between which there is an insulating gasket that holds them at some distance from each other. The air cavity that has turned out between them creates a certain barrier to the leakage of heat from the inside and the penetration of cold from the outside. At the same time, the transparency of such a system is very high, even higher than that of a traditional double window.
The choice of plastic windows is also connected with aesthetic demands: it is no coincidence that windows are the eyes of the house, so they must be beautiful! What plastic windows are better? We choose according to the profile, double-glazed windows, fittings How to choose plastic windows. Responsive sets of the above criteria. High quality parameters (and priority - technical safety) must meet all individual structural elements, namely: profile; glass fittings.
Seat for installation of a double-glazed window One of the most important parts of a metal-plastic window is a double-glazed window. Both the light transmission of the window and its heat-saving properties depend on its quality - one of the main characteristics, because of which plastic windows are selected.
Multifunctional double-glazed windows have good light transmission. Due to the thickness of the profile, they are resistant to mechanical damage.
Reinforcing profile PVC insert By itself, polyvinyl chloride, even modified with chemical additives, is not a very strong material mechanically, moreover, it is prone to thermal deformation. But in combination with metal inserts, its stability and resistance to mechanical stress increase by an order of magnitude. It is more reliable to fasten all the fittings to the metal, which is quite a lot in a modern window.
Most of them are made on the basis of high-quality float g
Wooden frames, as an alternative, also cannot be called an example of environmental friendliness. In their production, glues, impregnations, varnishes and paints are used, often with a dubious composition.
Poor-quality elements can also provoke other problems with the operation of a double-glazed window. Sealant Sealant is responsible for a snug fit of the sash of the window structure and noise insulation, the absence of drafts. To choose a sealant for plastic windows, it is enough to know that high-quality sealing rubber or silicone is elastic, pliable, and odorless. To check the quality, you can compress the media and then release it. A good seal is easily pressed through and quickly returns to its original shape, there are no creases on it.
The product passport must contain all profile parameters, including resistance to low temperatures, or simply indicate the degree of performance. If it is written that the profile belongs to a normal or frost-resistant type, then you can buy without fear, it is designed for negative temperatures.
What you need to know when choosing a window profile The window profile is the window itself, the frame where the double-glazed window is installed. Profile properties usually depend on the material of manufacture. As a rule, this is polyvinyl chloride (PVC), there are also aluminum and wooden windows. In PVC profiles, internal compartments are important, filled with air and sealed with plastic on all sides. Their purpose is the same as that of a double-glazed window: to retain cold with the help of low thermal conductivity. The more such chambers with voids (and the better they are arranged), the more efficiently the window will savebe your warmth.
