Glass or a combination of several glasses is the main part of the window structure, which occupies the largest part of the opening by area. Therefore, energy efficiency indicators depend to the greatest extent on the correct choice of glass.

When installing metal-plastic windows, the difference in the microclimate becomes noticeable immediately. With wooden structures, the air in the room was similar in humidity to the air outside the window, and the temperature in the room fluctuated noticeably with changes in the weather.

Sometimes, when replacing old wooden structures with new metal-plastic windows, black spots appear on the slopes and quickly grow. It is not difficult to recognize mold in them. If no drastic measures are taken, the colonies of the fungus will increase rapidly. What caused the problem, how to deal with it, and also how to prevent the appearance of mold – read below.

This question is most often asked by the happy owners of brand-new metal-plastic windows. In wooden structures, "tears" on the glasses appear much less often. With the recent replacement of old structures with PVC, the owners begin to notice moisture on the windows, although it would seem that nothing in the room has changed. Where does the water come from?

In order to provide comfort and protection from loud sounds in the house, it is possible to install windows with good sound insulation indicators. This will give you the opportunity to relax or work in peace, even if the windows of your house overlook a busy highway, train station, construction site or playground. So when choosing metal-plastic windows or replacing them, among other things, pay attention to their noise insulation characteristics.

If you ordered windows from a trusted supplier, and the installation was carried out by highly qualified specialists, then the situation described in the title rarely occurs. All the rules of care and adjustment are usually told when buying, installing and subsequent maintenance. However, if you have a window sash (or a door leaf) hanging on one hinge, or you need to make extra efforts to close the window — it's worth figuring out what the problem is.

The energy efficiency of a window is its basic characteristic. But the level of protection of windows from heat loss is radically different depending on the quality of the assembly, profile, fittings and double-glazed windows.

Thanks to the thoughtful design of the fittings, the adjustment of plastic windows with your own hands is quite possible. Moreover, it must be carried out periodically — even the heaviest shutters during intensive operation can deform over time, which will lead to problems in opening and closing the plastic window. Another possible problem is a decrease in the density of the sash pressing against the frame, which is also eliminated by adjustment.
