PVC plastic windows
The fact that PVC windows in many of his qualities is much better than ordinary wood window designs, it is now difficult to challenge someone else. windows are choosing now, thousands of people. And this choice is determined primarily by the benefits of plastic windows - plastic windows comfort, warmth in the apartment guarantee. But here they provide an ecological safety. Simply put - there is harmful to put plastic windows? Safety of plastic windows is associated not only with their reliability and durability. Materials of plastic windows that are used to manufacture profiles, have been successfully applied not only in construction is due to its environmental characteristics. Petrochemical products are often a threat to health because of the hazardous emissions that may cause many diseases.
Polyvinyl chloride (PVC), from which the profile of plastic windows, belongs to a group of thermoplastics. Its composition - ethylene (47%) and combined chlorine (57%), derived from common salt. Pure PVC is a powder. To get a profile for the manufacture of plastic windows in the powdered material is added stabilizers, modifiers, pigments, and adjuvants.
The greatest concern of those who wondered whether the harmful PVC windows is always a lead, used as a stabilizer. PVC, he is in a bound, that is biologically dormant. Therefore, the finished plastic windows lead is not isolated. However, those who still doubt it can take advantage of new developments leading European companies, ordering new windows environment - their profile is produced with the use of calcium compounds and zinc instead of lead.
Often quite safe under normal conditions the materials are particularly at risk person for any emergencies. For example - in case of fire. In this case, double glazing pvc possess much better properties than the windows in wooden frames. PVC profile does not ignite, and even serves as a definite obstacle to the spread of fire. Released by burning PVC hydrogen chloride due to a sharp odor is detected at the most minimal concentrations. Reacting with water vapor, hydrogen chloride forms hydrochloric acid that causes corrosion of metal structures. However, its concentration is so low that not a danger to human health.
Carbon monoxide, known as carbon monoxide has no smell. But its release can not be avoided completely during combustion of organic materials. However, since the burning of PVC is much slower than, for example, wood, for that concentration in which carbon monoxide is deadly to humans, by burning (or rather even say melting) PVC to a very long time. And more trouble may come from the allocation of carbon monoxide other burning objects or building materials, rather than from PVC.
Therefore, if you have to buy plastic windows, do not doubt that they are safe and do not listen to all sorts of "stories about plastic windows. No insurance company or in America or Europe do not consider the profile of PVC as a material capable of creating an additional threat to human life and health at fires and natural disasters, and even more so during normal operation in a residential installation.
