In the late 19th century, the owner of a paper mill and a great experimenter, American Augustine Sackett decided to create a cheap and easy to manufacture building material, which would be able to replace the wooden lath and plaster - basic building technology for buildings of that time.
However, the board he planned to do not wood, and paper.For this, he glued 10 layers of paper and a plaster solution was dense and lightweight layers, which, in recognition of the Sackett, "had the advantage in manufacturing, fire resistance, dryness, comfort and ease of construction."In addition, he stressed Sackett, with its boards' room gets ready for immediate move and had no cracks, which could not be avoided with plastered walls.And they had a smooth surface and can be painted, as well as plastered walls. "Then Sackett invented a machine for proizodstva their boards and May 22, 1894 received a patent for his invention.It is from this date of the official history of the drywall.
Almost a decade and a half h
As mining engineers, they realized that the natural properties of gypsum (porous structure, non-toxicity, non-flammability, the ability to absorb moisture), allow it to be an ideal building material.
In 1932, the brothers were given the right to develop a gypsum mine in Schengen, and opened the first factory for the production of dry building mixtures in Pearl River Moselle.It KNAUF subsequently become a key producer of gypsum-containing construction mixtures and drywall in the world.To achieve this will be possible thanks to the constant upgrading of technology.In 1958 the factory opened a line for the production of gypsum boards.The company's strategy has been focused not only on what to produce and sell sheets, but also the fact to offer customers the whole palette of materials for construction and repair.But the most important thing was that the German proizoditeli predetermined reference quality standard drywall supported by today.Love to innovation has allowed to create Knauf drywall for all occasions.Standard sheet GCR is used today for the construction of interior walls, ceilings, niches;waterproof sheet (gypsum plasterboard) is able to withstand sudden changes in temperature and humidity;and vlagoognestoyky list (GKLVO) has more and enhanced fire resistance.Also produces sheets (plates) with high noise protection properties and sheets for protection against X-rays.
Today, more than 80% of all interior solutions around the world made with drywall.
That is, the vast majority of people on this planet chooses the sheets GCR for the internal arrangement of their homes.This is not surprising, because drywall is loved not only for its technical properties, but also for the ease and speed for assembly.In Russia, the first experiments were undertaken the implementation of drywall in the 50s, thanks to Alfons Knauf.But finally caught drywall in our country in the era of the so-called western renovation in the 90s of the last century and since then remains the most preferred material for the repair and decoration.
