High demand for German goods is confirmed by great demand for them, in particular, Germany today is a world leader in the market of plastic windows. It is worth noting that they were invented precisely in Germany, and from there they began to spread around the world. The first plastic windows in their modern version appeared in 1947 – Rehau began to produce them. The fact that today, after more than sixty years, these windows still continue to serve people, is indicated about the quality of those who have not yet been quite perfect German windows.
Today, many companies for the production and installation of plastic windows have appeared, and their prices for their products may vary quite much. Therefore, buyers have a question – how cheap window constructions differ from their expensive analogues, since it is very difficult to find external differences in a non -specialist. First of all, it is necessary to consider such a factor as the stability of the quality of products. It includes both the stability of the production process at each stage and the stability of the quality of the raw materials from which window profiles are made. Since to maintain all the parameters of quality and constant control at the proper level of all quality parameters, this affects the cost of plastic windows towards the increase. Additional expenses are also required by special equipment and highly qualified employees responsible for the production process.
Another factor that affects the quality of PVC windows is the quality of raw materials. Polyvinyl chloride powder is the main, but not the only component of the profile. To ensure all the required parameters, polyvinyl chloride is mixed with other components, including substances that increase strength, modifiers, stabilizers and much more. Among these components there are also very expensive ones, such as, for example, titanium oxide, which gives a white profile. It is thanks to this addition that German windows differ in such a dazzling color. If you save on it, the windows, of course, will cost less, but in a few years the profile will turn on.
No less important is how well prepared raw materials. All its components should be in certain proportions and evenly distributed in the mixture, otherwise weak areas may appear, which can subsequently crack. The weakness of the window structures is traditionally considered seals and double-glazed windows, however, if the profile is made in violation of the technology, it becomes fragile and can be destroyed after some time.
Another unpleasant surprise that low -quality plastic windows can be presented is the uneven profile. When it is cooling, any violations of the conditions can cause deformation. It can be almost inconspicuous, but it will deliver a lot of trouble during operation – the window sash can be poorly closed, or through small cracks it will blow out the wind, nullifying all the benefits of thermal insulation. High -quality German windows are characterized by excellent smoothness of the profile.
The convenience and ease of operation of plastic windows, their impeccable work throughout the entire service life is largely due to the quality of accessories. This concept includes shut -off mechanisms, spinger, pens and other mechanisms that provide opening and closing the window sashes, their fixation in a particular position. Depending on the type of opening the wings, the fittings can be rotary, rotary-oxidized, shtulpa or phymic.
The easiest type of window fittings is a rotary, which ensures the opening of the wings with turning it around the vertical axis. More complicated, and, accordingly, more expensive, the fittings of a rotary-oatmeal, allowing to open a window sash not only in the vertical, but also in a horizontal plane, which is very convenient for ventilation of the room.
Pileplain fittings are used for swing windows, which consist of two wings, between which there is no vertical jumper. Figuishing window fittings are used in cases where the width of the sash is greater – with its help the sash open in a horizontal plane and fixed in this position.
In most cases, accessories intended for high -quality German windows have additional opportunities. So, for example, high -quality accessories are equipped with a microlift – a device that lifts the sash when it is closed to avoid sagging it. It can also be equipped with all kinds of adjusting elements that provide the ability to regulate the position of the window sash in a variety of positions.
