Basic Information About Cleveland Drywall Corporations

By Sandra Howard


Drywall is a flat panel that is made of two layers of paper sheet that sandwich gypsum plaster. The product has several other names such as wallboard, plasterboard, and gypsum board. The motivation behind the invention of this product was for it to replace traditional lath and plaster. It was considered a faster option. Several global companies today produce and market the product worldwide. Cleveland drywall companies have long histories of producing quality products

The first company that produced plasterboard came into existence in 1888 and was incorporated in Rochester, Kent. The predecessor of the plasterboard was called a Sackett board and was invented by Fred Kane and Augustine Sackett in 1894. Since its invention, plasterboard has undergone a lot of evolution that has seen it being refined to the fine product that it is today.

The US Gypsum Corporation acquired Sackect Plaster Board Company in 1910 and they formulated another product called Sheetrock in 1917. Installation of Sheetrock was made easier and it had fire resistance capabilities. When air entrainment technology was invented, plasterboards became lighter and less brittle. Further evolutions were done in joint treatment materials and treatment.

Plasterboard is made composed of gypsum plaster placed between two layers of paper. The production process involves heating the raw gypsum to remove water before re-hydrating slightly to make the hemihydrate. The resultant plaster is then mixed with fiber and several other materials to achieve specific qualities. The materials added include foaming agent, retarder, additives, plasticizer, wax emulsion, fine crystals of gypsum, and EDTA.

Every substance added into the gypsum has a specific function in the end product and the mixture itself. For example, starch acts as a retarder, fine-crystaled gypsum serves as an accelerator, wax emulsion reduces water absorption, and other additives provide fire resistance and reduce mildew. The final mixture is wet and is spread between two heavy paper sheets or fiberglass. The sandwich is placed in a drying chamber to dry and become hard enough for use in building.

Drywalls have numerous uses in homes. To begin with, they are good for reducing sound transmission in and out of a room. Several plasterboards are layered together when they used for soundproofing. Special boards for soundproofing are also available in the market. The constructor must follow certain construction specifications when using the boards to soundproof a space. For example, they have to use steel studs, wider stud spacing, insulation, and double studding among others.

Water and moisture are very destructive to drywall given the materials the product is made of. Exposure to moisture causes it to soften and eventually turning to a gooey paste upon prolonged immersion. Exposure to moisture also leads to the growth of mold. This is because organic additives and paper facings in the plasterboard are good food for mold.

It is quite a challenge to dispose used plasterboards because it is often not recycled. Some landfills have made it illegal to dispose the material in their sites. The best disposal method entails taking back the board to the producer so that it can be manufactured into new ones.
