With the increase in population and people's desire to live in cities, the issue of noise pollution has become a serious problem. A problem for which there was no proper solution until a few years ago. People who lived near highways and crowded neighborhoods did not have peace and comfort because of the noise of cars.
But gradually with the advancement of technology, various methods were created to solve the problem of noise pollution. One of these methods was the use of double-glazed windows in houses. Double-glazed windows are a type of sound and thermal insulation that prevent noise and cold from entering the house. Now, after a few years, you rarely see a renovated building that does not use double or multi-glazed windows. . Even many owners of old apartments or villa houses changed their windows to double-glazed or upvc windows in order to get rid of the ambient noise.
What is upvc double -glazed window?
Double-glazed window or upvc is abbreviated as Unplasticized Polyvinyl Chloride. As the name of this window suggests, 85% of the upvc composition consists of crude oil derivatives. Its other ingredients are edible salt, vinyl chloride, stabilizer and filler. The ingredients of double-glazed windows prevent the transmission of sound, heat and cold to the environment. This characteristic of upvc windows made double-glazed windows to be a good alternative to wooden, iron and aluminum windows today.
Double-glazed windows are made of several layers of glass with upvc frames that are separated from each other by a spacer strip. .
UPVC window history
upvc profiles were first produced in **** in Europe. In industrialized and developed European countries, the use of uPVC in building construction has greatly expanded and has become a suitable alternative to old windows.
The history of the production of double-glazed windows in Iran goes back to the late 50s. But in the beginning, the production and use of double-glazed windows in Iran was accompanied by problems. The lack of sufficient equipment and technology and the lack of people's awareness of the benefits of uPVC caused these windows to not be well received in Iran. And its use became popular in the construction industry.
UPVC and PVC What are the differences with each other?
PVC and UPVC are both the most widely used polymers in the world, which have many uses in food, clothing, packaging, industry, medicine, etc. PVC is a plastic and elastic material that is made of ethylene, chlorine and vinyl chloride compounds. PVC is used for industries such as pipe making and medical purposes such as dentistry.
Polyvinyl chloride or PVC is also a component of upvc windows; But for the construction of double-glazed windows, besides PVC, a stabilizer and filler material such as calcium carbonate is also used to increase the resistance and strength of upvc.
