The most common questions that buyers have is how to choose the most optimal plastic windows? How to choose a window that can last a long time? Which pvc profile is better? This material will help answer your questions and help you figure out how to choose metal-plastic windows.
A weighty selection criterion is the price of a plastic window, the value of which depends on a number of components: double-glazed windows, profile, fittings. On any of them, the manufacturer, if desired, can save money in order to provide cheap samples of economy-class windows. The price also depends on the quality of not obvious details: fasteners and assembly materials, window seals, reinforcement, etc.
Selection of double-glazed windows
To choose plastic windows, you first need to choose double-glazed windows. For many, plastic windows are double-glazed windows. In fact, plastic windows consist of three components: glass units themselves, profiles and fittings. Double-glazed windows are a set of chamber glasses. Your task will be to determine the number of cameras, glass structure and the presence of a protective film. The number of chambers is responsible for the thermal insulation of the window - the more chambers, the higher it is.
For our latitudes, the presence of 2 chambers is optimal - this is more than enough to keep heat. Please note that the distance between glasses should not exceed 16 mm. This way you will save on the profile (it will take less material). Protective film or dusting prevents infrared rays from entering the room. And the space between the glasses can be filled with a special gas. This helps keep you cool during hot summers.
Pvc profile selection
Various factors influence the thermal insulation properties of a plastic window. First of all, it is the recipe of the raw materials from which the pvc profile is made. The next is the thickness of the outer wall of the profile (should be from 3 mm to improve thermal insulation and stiffness indicators). And, of course, the quality of the equipment used for the manufacture (the quality is not cheap, which also affects the price of the finished product). The adhesion density in the PVC product and the quality of the profile surface depend on the extrusion speed (the passage of the profile in the burning state through special dies, at which it acquires the desired shape) If longitudinal depressed stripes are visible on the profile, then this is the result of an incorrectly selected extrusion speed (as a rule, high). Probably in this situation, and the wrong composition of raw materials.
And the last is the number of chambers in the pvc profile (easily determined from the profile section by counting vertical chambers from the bottom to the top point of the profile). These cameras inside can be split into mini-cameras using stiffeners. The most common options are five- and three-chamber profiles.
Five-chamber profiles are 70 mm thick and are more expensive. However, there are also profiles with the same thickness of 70 mm, but with only three chambers. Such samples are quite difficult to distinguish externally from five-chamber ones, but in terms of heat saving they are noticeably inferior to the latter. When choosing a profile, be sure to consider the weather conditions, frosty winters and hot summers, as well as the relative humidity of the climate.
What you need to know when choosing accessories?
You cannot make the choice of fittings on your own if you are not a repair engineer yourself, so here professionals will make a decision for you based on your other preferences. They know exactly how to choose plastic windows and fittings for them. The most demanded manufacturers in the hardware market are Roto Frank, GU, Winkhaus, and Siegenia Aubi.
The quality and functionality of the window depends on its reliability, so the choice of accessories should be taken with the utmost seriousness. Often, manufacturers, wanting to reduce the cost of window construction, consider it possible to install low-quality fittings. The result of such savings is a window with fairly good profile characteristics, but not meeting high operational requirements due to the unstable operation of the fittings.
Today, when the market for window structures is overcrowded, many of the buyers, getting lost in their choice, pay close attention to the quality of the profile, sometimes forgetting that the elements of the fittings play a significant role in the reliable operation of the window. Opening mechanisms, latches, hinges, latches, locks of decent quality ensure durability and reliability of the window mechanics, thereby extending the service life of the entire structure.
The work of the mechanisms that make up the window system must be well-coordinated and stable, the fittings must be resistant to external influences - changes in temperature, humidity, etc. The window should close tightly and keep the sash position in the selected mode. The service life of high-quality fittings should be at least fifteen thousand cycles.
One of the components that determine whether the fittings for plastic windows are of high quality are the characteristics of the strength and reliability of structures and parts. Despite the simplicity of the fasteners, each of them plays a critical role in the durability of the structure. Underestimating reliability and saving on significant elements of window frames can lead to serious consequences in the future. So, low-quality fittings will become the reason that the consumer himself will soon be unable to open the doors or put them on the ventilation mode.
When choosing what fittings are needed for plastic windows and doors, special attention is required to the characteristics of resistance to temperature extremes, as well as to mechanical damage or weathering and the presence of an anti-burglar mechanism.
When determining the most important consumer characteristics, it is necessary to pay special attention to the following details of the mechanisms:
- Scissor arm;
- Window sash lifting mechanism;
- Slam stop;
- Hinges / reinforced hinges;
- Compensatory clamps;
- Swing mechanisms;
- Sash and frame fixing hinges.
And the most pleasant thing when choosing a window is to understand correctly the parameters by the type of opening by which the window will be operated.

Why do metal-plastic windows sweat? Quite common life situations are fogging of glasses when leaving the room, glass in the bathroom or windows in the apartment. Condensation is a problem that millions of people face. It is quite easy to identify the cause of this phenomenon if you consider several options. The main reasons for the appearance of condensation on metal-plastic windows, i.e. fogging are two factors - humidity and temperature. It is the change
