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
Rochester, Kent is where the first company to produce plasterboard was incorporated in 1888. Sacket board was the precursor to drywall and its invention was done by Augustine Sackett and Fred Kane. From the time of invention of plasterboards, they have evolved a lot and the product in use today has been refined to a high degree.
Sackect Plaster Board Company was acquired by the US Gypsum Corporation in 1910 and they came up with a product they called Sheetrock by 1917. Sheetrock made installation more efficient and incorporated fire resistance capabilities. With the invention of air entrainment technology, the product became less brittle and lighter. Further evolution occurred in joint treatment systems and materials.
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.
All materials added into gypsum plays a specific role within the mixture itself and the resultant product. Starch functions as a retarder, fine gypsum crystals function as accelerator, other additives function to reduce mildew and offer fire resistance, and wax emulsion reduce absorption of water. The resultant mixture is wet and it is covered with fiberglass or heavy paper sheets on either side. Hardening and drying is done in a drying chamber to make it sufficiently hard for building.
Homes find many uses for drywalls. First, they are used in the reduction of sound transmission from outside and between rooms. Using them for soundproofing requires many layers of plasterboard to be glued together. Manufacturers have also been able to design and produce special drywalls that can be used specifically for soundproofing. Certain construction details may need to be followed when using drywall to achieve soundproofing. For instance, there may be need for insulation, use of steel studs, wider stud spacing, and double studding among others.
Considering the materials drywalls are made from, the product is very sensitive to water and will be destroyed upon contact. When exposed to moisture, the material softens and with prolonged exposure, it turns to a gooey paste. The growth of mold is also encouraged by exposure to moisture. This happens because paper facings and organic additives included in plasterboards serve as food for mold.
Disposing used drywall has always been a problem because the material is often not recycled. Dumping of plasterboards has also been banned in some landfill sites. The most suitable disposal method is to return to the manufacturer to have the material recycled into new boards.
