The first synthetic plastic was developed by a chemist from the USA, Leo Beikeland, in 1907. He was in search of a synthetic substitute for shellac, a substance with properties similar to wax secreted by insects. His developments led to the synthesis of a liquid resin-like synthetic substance, which, when cured, resembled modern PVC in properties. Properties such as viscosity and elasticity in the liquid state made it possible to give it almost any shape. However, in the solid state, its strength characteristics were unusually high, and its resistance to aggressive environments was also striking in its wide range. After these properties were revealed, products made of a new material appeared all over the world. Polyvenyl chloride was obtained in 1385, but while its properties were being perfected, time passed. And only by the thirties was it "hard" and "soft&Plastic has become actively used on an industrial scale. Due to its unique technical properties, PVC has replaced such familiar materials as wood and rubber in the consumer market. To date, polyvinyl chloride is ahead of all known non-natural materials in terms of applications.

Constant developments in the field of chemical technology have contributed to the development of industrial applications of PVC. This is how the business of producing plastic windows began to gain momentum. The initial task of manufacturers of window structures was to increase the service life of manufactured products. After its achievement, the developers faced no less important tasks: environmental friendliness, thermal insulation, sound insulation, resistance to the influence of aggressive environments and an equally important variety of shapes and colors. Systematic work made it possible to quickly cope with the tasks set. The improvement of the production process for replacing stabilizers with heavy metals with stabilizers with alkaline earth ones made it possible to consider PVC windows environmentally friendly. Heat and sound insulation was achieved by increasing the width of the profile and increasing the double-glazed windows. Also, with the development of the technical process, aesthetic developments were taken into account in parallel. Arched, round windows and bevel designs appeared on the market, and manufacturers began to offer laminated films of various colors and shades.

In Russia, the plastic window is just over twenty years old. From the first days on the Russian market, it has become popular, as positive reviews from the West have already reached the Russian state. Due to its convenient ergonomics and ease of care, a plastic window has become the dream of many of our compatriots. The history of the plastic window does not go back centuries and continues to fill up...
