Drywall: creation history, scope and features
Drywall - building material, consisting of two layers of building cardboard and filled with solid gypsum dough with additional substances. It is mainly used as partitions and cladding, and is also used to repair ceilings. The standard size of drywall is about 120 centimeters wide.
This material was first created by the owner of a paper mill, Augustin Sackett in the United States, in the 19th century. Then the first prototypes were a “board” with a thickness of about 15 centimeters and had 15 layers of paper, separated by gypsum. The material was patented, but it was still far from modern. The development of engineer Clarence Utsman, who was also born in America, was recognized as a standard drywall.
In Russia, drywall for the first time began to be used as early as the half of the twentieth century, back in the Soviet Union.
One block of this material accounts for about 91.1% of gypsum and 5.78% of cardboard, and 1% of the mass is formed due to organic matter and moisture.
Drywall installation consists in gluing sheets of the finished material using mastic, or attaching to a special, pre-prepared frame with screws.
There are three types of drywall:
1. Drywall (GKL);
2. Moisture-resistant drywall (GKLV), designed for places with a high degree of moisture;
3. Drywall (GKLO) drywall, designed for use near open fire.
Over time, this material has earned a good reputation, primarily due to its low cost and convenience. In most cases, it is used in the construction of peripheral walls and as a canvas for the installation of another material (for example, a tiled coating).
Drywall also has high soundproofing potential. In particular, the space between the sheets is filled with glass wool, and the sheets themselves are joined to the wall, fastened to the reinforcing mesh with glue, where the joints are filled with putty.
Also, the material can be used to create buffer spaces where communication systems can pass (including power supply systems, communication networks, ventilation, gas supply systems, etc.).
In addition, drywall often began to be used not only for construction, but also for creating a new interior by enthusiasts.
The standard size of the drywall sheet is about 2500x1200 millimeters, and the thickness is at least 6.5 millimeters. Depending on the purpose and characteristics of adjacent coatings, the sheet size may vary. en.escortbayan.xxx
