The development of all gypsum boards begins with a mineral rock, which is gray to white in color and is called gypsum. The basic mineral is composed of calcium sulfate chemically combined with water of crystallization. The combined water makes up approximately 20% of weight of gypsum rock. This is the feature that gives gypsum its fire resistant quality and makes it so adaptable for construction purposes.
After gypsum rock is mined or quarried, it is crushed, dried, and ground to flour fineness, then calcined to drive off the greater part of the chemically combined water as steam. This calcined gypsum, commonly called plaster of paris, is then mixed with water and other ingredients and sandwiched between two sheets of specially manufactured paper to form various types of gypsum board or specially formulated and bagged for shipment as gypsum plaster or cement.
Gypsum boards are formed in a highly automated continuous process. After the gypsum board has set, the boards are cut to length, dried, prefinished if required, and packed for shipment. All processing is in strict accordance with specifications and complies with more than 256 procedures and work instructions to meet quality standards and customer's satisfaction.
ADVANTAGE:
Life Safety Protection
Fire resistance is inherent in the gypsum construction selected. The systems provide permanent fire resistance not subject to loss of water pressure or other malfunctions and problems which may occur in sprinkler systems.
Fire Resistance:
Gypsum will not support combustion. When attacked by fire, crystallized water in gypsum is released and turns to steam to help retard the spread of flame and heat and protect adjacent constructions.
Light Weight:
Gypsum board constructions weigh appreciably less than masonry assemblies of the same thickness. They reduce material - handling expense and may permit the use of lighter structural members, floors, and footings.
Sound Control:
Gypsum board construction offers excellent resistance to airborne and impact sound transmission without excessive bulk or weight. Resilient attachment of gypsum panels or bases further improves sound ratings, makes partitions ideally suited for party walls.
Versatility:
Gypsum board construction is suitable as divider, corridor and party walls; pipe chase and shaft enclosures; radiant-heat ceilings; exterior walls and wall furring; membrane fire resistant constructions. Adaptable for use in every type of new construction - commercial, institutional, industrial and residential - and in remodeling. It produces attractive joint - free walls and ceilings; easily adapt to most contours, modules and dimensions.
