The windows produced in the 60s had a service life of 40 years and met all the available engineering requirements. Since the production technology of plastic windows has changed many times, several types of products appeared.
In Russia, the most popular are the windows of economy and elite class. They differ significantly in price, but outwardly often look exactly the same. The cost is affected by the quantity and quality of double -glazed windows, the thickness of plastic profiles.
