Many companies offer to buy PVC windows, but do not explain the difference between a plastic and metal -plastic profile. And between them there is one significant difference – the metal -plastic profile contains an additional metal galvanized frame inside.
The frame helps to increase the strength and stability of the window structure. According to professional terminology, the frames are “reinforced with a galvanized profile”. Additional strength characteristics are not superfluous with strict operating conditions. For example, on the upper floors of skyscrapers, the load on the windows due to strong gusts of wind increases significantly, and ordinary windows may simply not withstand it.
Metal -plastic windows have undoubted virtues, which served as a guarantee and popularity. For example, they do not require special care. Once adjusted in accordance with existing conditions, in the future do not require the attention of the owners.
They are not sensitive to climatic conditions, successfully competing with wooden structures. However, the dispute around the wooden windows in terms of how natural they are continuing. Wooden frames are treated with special chemicals so that they lose hygroscopicity, become less suppressed by moisture, do not dry out, do not crack. After all manipulations with a tree using rather rigid chemistry, whether they can be attributed to absolutely environmentally friendly and natural?
As for metal -plastic windows, they do not distinguish harmful substances into the external environment, safe for the human body. The metal frame significantly extends the service life of the window structure. Features of the material allow you to make window frames of various configurations, sizes, forms.
When ordering the windows, you should decide on the conditions in which they will be operated. If a large load is supposed, it is better to order metal -plastic ones, which, possessing all the advantages of PVC windows, thanks to the metal frame, some useful properties acquire additional.
When asked which plastic windows are better, there is no unequivocal answer. Better those windows that most satisfy your requirements meet expectations. The choice is huge, in connection with which the consultation of a professional will not be superfluous.
