We can no longer imagine our homes without plastic windows, window sills and panels, we even have plastic dishes. Good or bad - our descendants will say. If we talk about the types of plastic windows, then their range is very diverse. There are imported products from Germany, Finland or other countries. But more often than not, another scheme works.
The profile is brought to our country with whips, and here, at Russian factories, products are made from it. Another option is when the profile is stretched with us, but from a material that was brought from abroad. There are products that are made from a purely Russian profile.
Therefore, plastic windows differ primarily by manufacturer, and hence by price. Russian products are cheaper than foreign counterparts. But there are other differences as well. Now you can order products from a profile that has 3 or 4 air chambers. Some companies produce 5-chamber windows. The thickness of the profile and its performance characteristics depend on the number of chambers. A frame with a thickness of up to 65 mm has 3 chambers, and a profile of 74 mm and above can even have 6 or 8.
If we consider the types of profiles of plastic windows, they differ not only in the size of the frame and the numbercameras. For temperature indicators, the thickness of the walls of the plastic is also important. Even a reduction of just 2 mm provides significant cost savings, but worsens thermal performance.
Types of plastic windows also differ in the metal located inside the plastic profile. The closed circuit allows to withstand large static loads. This is especially important on large openings or when glazing balconies, when the blocks are made in a single structure from top to bottom. Wind load is also felt in high-rise buildings. Metal with an open contour is made in the form of the letter "P". It reduces the cost of the profile, but also weakens its characteristics.
If we are talking about the types of plastic windows, then it is necessary to mention their exterior finish. The cheapest window is made of white plastic. A painted profile or laminated with an oak-colored film will cost more. The painting method is also different. If it is applied to an already finished profile, then such a window is cheaper than if it is made from an extruded profile. Dyeing during the manufacturing process gives a better finish as the paint particles mix with the top layer of plastic and create a single fusion.
The presence of lamination allows you to expand the types of plastic windows for finishing the profile. You can order a window with an imitation of walnut or even cherry. True, all this affects the cost. The shape of the window also makes a difference. Windows are rectangular, in the form of a trapezoid, a circle ortriangle. Modern fittings allow you to open almost any configuration of windows. The price directly depends on the characteristics of the selected double-glazed window.
Therefore, when choosing a profile or a company that produces it, pay attention first of all to performance characteristics. But it is better to consider the window in conjunction with the installation. Even an excellent warm profile with poor-quality installation will not be able to protect the room from environmental factors.
