Increasingly, we are faced with advertising of various manufacturers, which are obsessively or intriguing that they have the best plastic windows, favorable prices, discounts, promotions, and so on. The market offers such a large number of plastic windows and in such a price scatter that getting lost in this sentence is very easy. What you need to know to choose high -quality windows without overpaying, or not to chase the cheapness?
Of course, most are trying to save on almost everything. And plastic windows are no exception – low prices are so attractive that many do not even think that later these cheap windows will cost them much more expensive.
When choosing between the same windows of different prices, take an interest in the manufacturer and stability of production, the quality of the raw materials used. The compliance of the physical and mechanical properties speaks of the RAL certificate or the certificate of conformity, and the indicator of the stability of the physical and mechanical properties of the products and its control is the certificate of Din END 9001. These certificates should have the past for any manufacturer, whether it be a large company or private person.
How the control of quality stability affects the total cost of plastic windows? First of all, it should be said that the control system itself is not cheap, since it involves the use of laboratories in which the quality of raw materials, personnel, time expenses, and a special documentation system is studied is studied. In addition, the control system excludes the supply of a poor -quality or defective product to the market.
The second parameter that affects the price of the window is the actual quality of raw materials. Modern plastic windows are produced from many high -tech components, and the source material – PVC – enters production as small white powder. To make the window profile out of it, it is mixed with stabilizers, modifiers, reagents, fillers and other necessary additives. The selection of additives depends on further processing and requirements for the product, since it is on them that the properties and quality of PVC editions depend on them.
Also in the production of PVC profiles, various chemicals are also used, which also have a considerable price, for example, titanium oxide, which is responsible for both the white profile whiteness and its preservation for a long time. This substance should be clean and sufficiently, otherwise a few years later the profile will darken.
Also, the manufacturer must responsibly approach the quality and distribution of modifiers in the mixture that ensure the strength of the profile.
In general, we can say that high-quality window PVC profiles have a certain lower price bar, and if the price of the profile is below this level, you should think about the quality of such products. Having saved on the profile, you run the risk of spending much more on its repair in the future, replacing components and windows as a whole.
