A wide variety of plastic windows, which is now observed in the markets of the country, makes you think about the correct choice of one or another window. Therefore, in order to make the right choice that will meet your criteria, you need to know the following about plastic windows.
First you need to understand the structure of the plastic window. The window consists of a frame, glass unit and fittings. This is the simplest kind of “blind” window that will not open. If the window opens, then another element will be present, which is called a sash. This is the part of the window that is attached to the frame and performs the function of opening and closing the window. Also, the window can be divided by a vertical or horizontal bar, which is called an impost.
Therefore, you first need to decide which window you need. If you choose a completely “blank” window, it will be impossible to wash it outside and ventilate the room. But thermal protection will be more effective. A fully opening window is also not very efficient and convenient to use. Heat will come out more, and such a window is not very convenient to use. Therefore, you can choose a combined version. That is, so that one part of the window is “blank”, and the second part can be opened. It is ideal for living quarters. Please note that windows can be opened vertically, horizontally, with a turn and tilt. Also, the window can combine all methods of opening and closing. But the more complex this method, the more complex the mechanism that must be used when assembling the window. Accordingly, its cost will also increase..
Next, you should choose a suitable glass unit. Now on the market there is a fairly wide selection of double-glazed windows, from single-chamber to six-chamber. A single-chamber double-glazed window consists of two glasses, which are hermetically inserted into the frame, and an air gap is formed between them. In a double-glazed unit, a third glass is inserted between the two panes. Two chambers with an air gap are formed. In a three-chamber double-glazed window, three chambers are formed according to the same principle, and so on. To improve the thermal insulation properties, these chambers can be filled with special gases (argon or krypton). You should also pay attention to the chamberiness of the frames. Frames also come with several air space chambers. And the more cameras there are in the frame, the better the soundproofing and heat-shielding properties of the window. Also, these properties are affected by the presence of cracks in the window opening, which can form with improper installation or poor-quality sealant. When choosing a double-glazed unit, it should be borne in mind that the larger the chamber of the glass unit, the heavier the structure. And if the window opens, then after a while the sash may sag under its own weight and not close hermetically. And the window can lose its thermal and noise insulation properties due to the formed cracks. Therefore, with proper and high-quality installation, a two-chamber double-glazed unit may be better than a six-chamber one. Also, for sound insulation and thermal protection, you can use additional frames from the outside. This will increase the chamberness of the frames, which will improve the protective functions of the window..
There are some more details that should be noted. The overall structure of the window should not be heavy, so as not to sag over time under its own weight. At the same time, it should be tough enough and not loose. For opening structures, it is important that there is a metal reinforcement inside the structure. All fittings should be attached to it. If the hardware is attached directly to the plastic, then it quickly fails and can damage the plastic. And then the replacement of fittings will be problematic or even impossible..
Therefore, a good quality window does not have to be the most expensive six-chamber glass unit. You can find the right window at an affordable price from any expensive and high-quality manufacturer. Also, a lot depends on the quality of the installation and additional accessories (seals, handles, etc.), which should not always be saved.
