PVC windows have recently appeared on the market, the cavities of which are not filled with air, but are filled with foamed heat insulators - expanded polystyrene, for example, or filled with fiberglass materials. Even with a relatively small number of chambers, their thermal insulation characteristics are much higher than air ones. But for now, their price is also higher.
PVC used for the production of profiles has a number of features that manufacturers are constantly struggling with: 1. Sufficiently high linear expansion, reaching several millimeters per meter of length. In order to compensate for this phenomenon, it is necessary to leave special gaps, use reinforcement and correctly calculate the number of fasteners. The same feature of the PVC profile limits mamaximum dimensions of window structures. 2. Low coefficient of elasticity, but even at the factories it is leveled by the use of metal inserts and the correct calculation of the thickness of the inner walls, which are stiffeners. 3. Insufficient temperature stability and UV resistance. Manufacturers also learned to deal with this drawback by introducing special modifiers and stabilizers into PVC, which preserve the color and structure of the material. In high-quality windows, such additives serve no less than the entire structure. They are, in most cases, completely harmless to humans. But if the frame emits a pungent smell that does not disappear for a long time, do not buy this window. It used lead or cadmium, or even more dangerous chemicals, instead of harmless zinc and calcium.

How to choose metal-plastic (PVC) windows, so as not to doubt their quality? Which, according to experts, plastic windows are better to put in a country cottage, and which ones - in an apartment in a city skyscraper?
Metal strips are hidden inside the profile and act as a strength enhancer. Sometimes windows of a similar design are called metal-plastic, which is more true than just plastic or PVC. The function of metal inserts is very important to ignore.
On the vast expanses of the Internet, a lot has been written about how to choose plastic windows. Nevertheless, we will give a number of general professional recommendations for those who are going to order windows for a house or apartment, but have not yet decided on their choice. Sections of the article: Choosing a plastic window - where to start Window configuration and design How to choose the right color for metal-plastic windows How to choose a double-glazed window for a plastic window Which profile to choose for windows Choosing fittings for plastic windows Mistakes when choosing plastic windows Where to start choosing plastic windows Almost everything who has on the agenda the replacement of old or the purchase of new windows, they begin with the selection of a profile system. And for some reason, it has taken root that the question “which plastic windows are better to install” is immediately associated with the name of the plastic manufacturer. For example, everyone knows Rehau windows. But there are no Rehau windows - there are metal-plastic windows from the Rehau profile. Moreover, the profile itself is only a plastic stick 6.5 meters long. Of course, a PVC profile system is a very important component, but we will do the right thing and, for starters, decide on the configuration. That is, we will decide how your new window will look like. Window configuration and design The shape of the opening (a niche in the wall into which plastic windows are installed in a private house or high-rise building) determines the final form of PVC structures. The most common shape is the classic rectangular, which is the generally accepted standard. But there are also non-standard ones - arches, trapezoids, triangles, a polygon, an oval, etc., which brings its own charm and zest to the home. Configuration and design of plastic windows On the basis of the opening, it is necessary to create a general configuration and design of the future window: visually divide the window niche into vertical and, if necessary, horizontal elements. In this way, you will create a frame with a certain number of sections; determine which of the resulting elements will open (sashes), and which will be “deaf”; think about the color of the windows; How to choose the right color for metal-plastic windows In fact, there are no specific recommendations here, you can choose a color coating, for example, to match the color and texture of wood or monochrome white. The lamination palette is very large, and the lamination film is applied both on the inside of the frame and on the outside in various combined options.
Most heat escapes through a double-glazed window, so you should pay close attention to it. Often, to improve the characteristics, silver ions are sprayed onto the surface or argon gas, which has low thermal conductivity, is pumped inside. As a result, such double-glazed windows are more expensive, but they also retain heat 1.5 times better than ordinary ones.
Intra-profile ventilation of PVC windows The method of ventilation of a room with closed sashes can be implemented in different ways. Some manufacturers install a slotted, folded or overhead ventilation valve in the PVC profile.
