![]() The remaining seams are concealed using a joint compound filler and tape. The sized panels are fixed to wall studs or ceiling joists with nails, glue, drywall screws or drywall fasteners. Construction workers cut the panel to size, usually by scoring the paper and breaking the core manually. However, even that comes under the classification drywall.īoth drywall and Sheetrock are used with the same basic techniques. This manufacturing process is the same for the Sheetrock brand, but for the use of a few chemicals unique to the brand. To make drywall, the wet gypsum core gets sandwiched between heavy paper or fiberglass mats. The gypsum plaster core is made out of fiber, a foaming agent, finely ground gypsum crystal and additives. Finally, Sheetrock offers stronger panels that are resistant to abuse such as indentations, abrasion and even penetration.ĭrywall consists of a core of gypsum plaster pressed between two thick sheets of paper. ![]() Exterior ceiling board is weather-resistant, so it can be used outdoors. Sag-resistant Sheetrock is light-weight, thus resisting sagging. Like regular drywall, Sheetrock also comes in a foil-back variety as well as a mold and moisture-resistant option, including the Fiberock panel with is the top choice for this necessity. There are three grades of fire-resistant panels, including one with a 3/4-inch Ultracode core. Sheetrock also comes in different varieties, including the regular core panels in 1/4-inch, 3/8-inch and 1/2-inch thicknesses. Drywall can be lead-lined for use around radiological equipment or foil-backed as a vapor barrier. Enviroboard is made from recycled agricultural materials. Soundboard uses wood fibers to increase sound transmission while soundproof drywall uses damping polymers to decrease sound transmission. Cement board is even more water resistant. Similarly, blueboard utilizes additives that make the paper both water and mold resistant. ![]() Greenboard features green paper, to which an oil-based additive is used to provide moisture resistance. Fire-resistant drywall features additives to increase this property. Standard panels can come in 1/4-inch to 3/4-inch thickness. However, other companies that make drywall are: National Gypsum Company, Titan Commercial Products, and Allied Manufacturing.ĭrywall comes in several different types. ![]() Gypsum Company may market their drywall as Sheetrock. Sheetrock is also used as a replacement for lath and plaster in the construction of interior ceilings and walls, though some Sheetrock is weatherproofed for exterior ceilings. Sheetrock is a brand of drywall, though because of its popularity, the term has come to be used interchangeably with drywall.

Sheetrock is a trademark for drywall made by the US Gypsum company. Drywall construction became prevalent as a speedier alternative to traditional lath and plaster. It is used to make interior walls and ceilings. Drywall is a panel made of gypsum plaster pressed between two thick sheets of paper.
