The market of plastic windows is oversaturated today, however popularity of this type of products still at height. Therefore when choosing plastic windows it is necessary to be guided first of all by quality of spare parts of window which can be manufactured by different producers.
Modern plastic window – multicomponent product. Several interconnected elements on which quality the functionality of all product depends are its part. Therefore when choosing plastic window (especially from inexpensive price niche) it is necessary to pay first of all attention to its constituent parts.
The profile is available in any plastic window in the form of the "belt" made of galvanized steel. The profile is necessary that the plastic window remained "at the dimensions" in case of seasonal variations of temperature. The qualitative profile has to have thickness from 1.5 mm that will provide the minimum deformation at temperature change and the long term of operation. Also, getting window, pay attention to plastic; if material of opaque color, then is better to refuse purchase. Similar plastic is capable to absorb dirt which is very difficult for wiping subsequently. It is more preferable to choose glossy products.
One of its characteristics – number of cameras. Usually it depends on temperature in the specific region. Than the climate is colder, that more cameras have to be in double-glazed window. If in your area temperature does not fall lower than 20 wasps in the winter, one camera suffices if reads off scale for minus of 30 wasps, it is better to get window with two cameras. It is impossible to exclude also such factor as noise isolation. If the window comes to the noisy avenue, the street, it is more preferable to establish window with triple-pane glass. Pay attention to distance between glasses; in qualitative product it has to be miscellaneous, - it increases efficiency of noise reduction. One more factor affecting quality of product – glass. It can be normal or energy saving. In the latter case the special sputtering or film which reflects warmly back to the room is used that gives the chance better to preserve warmly. In respect of safety, glass can be red-hot (at destruction it is scattered into small pieces without sharp angles) or "triplex". In the latter case the "threefold" design in which between glasses the transparent film is located is used, - at destruction of product to it splinters stick.
It has to be completely made of solid metal. The quality of accessories even if it and metal, it is difficult to define at once, is necessary time. One of indirect signs of good product, - availability of marking of the producer. Nevertheless the best option to avoid problems – acquisition of plastic windows from the famous producers.
