When ordering a new metal -plastic window, it is important to immediately determine its design, since this is the main thing than the plastic windows differ from each other. The appearance of the window also depends on the type of design, the convenience of its operation, price and other important nuances.
Consider the advantages and disadvantages of the main types of PVC windows, by the method of opening the wings:
Deaf window
Deaf windows, that is, windows in which the wings do not open at all, are not in great demand, despite the fact that they are the cheapest and most reliable. Windows with this design are inconvenient in operation, since they cannot be washed outside, unless it is on the ground floor or next to the window in which the wings open.
Window with a folding sash
Such a window design (when the sash can only be slightly opened for ventilation, but not to open completely), a little more convenient than the previous one, but not quite. Most often, such windows are installed only due to the impossibility of installing another type of window.
Window with a rotary structure
This type of window, with an opening sash, can be called traditional. Thanks to the rotary structure, the window is convenient in operation, but if you want to put the PVC window on the balcony or in a narrow corridor, then you should look at other windows.
Turn-oxide wings
The advantages of this window design are obvious, so the windows with a rotary-oxide structure are sales leaders. Complex accessories allows you to open the wings in any direction, which is very convenient.
Sliding windows
This design of metal -plastic windows appeared recently, but immediately became in demand, since it is unusually convenient to use sliding windows on balconies or loggias.
However, PVC windows differ not only in the way of opening the wings. Features in the design also have very long or very high windows.
High windows
When installing a high window, it should be borne in mind that its sash will be much heavier than usual (and this will give an additional load on the loops). In order to make such windows more convenient and safe, they are made with phrama.
Long windows
The problem of too long windows is that it is inconvenient to wash from the outside. This problem can be solved by an increase in the number of opening wings. The more opening wings, the window it will be more expensive, but the more convenient it will be used.
