What is Gypsum Board ?
Due to its inherent fire resistance, gypsum board, commonly known as drywall is the premier building material for wall, ceiling, and partition systems in residential, institutional, and commercial structures. Designed to provide a monolithic surface when joints and fastener heads are covered with a joint treatment system, gypsum products also provide sound control, economy, versatility, quality, and convenience.
Gypsum Board InstallationGypsum board is the technical product name used by manufacturers for a specific board with a gypsum core and a paper facing and may be further described as follows:
Gypsum board is one of many gypsum panel products, defined in ASTM C11, Standard Terminology Relating to Gypsum and Related Building Materials and Systems, as "the general name for a family of sheet products consisting essentially of gypsum." This term includes gypsum board, glass mat gypsum panels, abuse-resistant, and impact-resistant gypsum panels and gypsum shaftliner panels.

FAQ
Joints between boards in fire-rated assemblies must be in "moderate contact," meaning that the gypsum boards should be touching and gaps minimal. All gaps and joints in such assemblies must be properly taped and filled with compound. Around electrical boxes, the UL Fire Resistance Directory references no more than a 1/8" (3.2 mm) gap/joint, though in the field this can be difficult to attain and measure. All gaps must be filled with joint compound, fire-rated caulking or other materials/means suitable, per the local code authority. In non-rated construction, joints up to ¼" (6.4 mm) tolerances are acceptable when filled with setting type, all-purpose joint compound. Note that the type of compound used to prefill gaps in the joints must be compatible with the compounds used to tape and finished the walls and/or ceiling. More information on joint tolerance is contained in the Northwest Wall and Ceiling Bureau Document #500-103 Gaps at Gypsum Board Joints available here.
Q2: Is it necessary to tape the joints in the base layers of fire-resistance rated multi-layer gypsum board systems to maintain the fire resistance rating?
No. In multi-layer systems, the joints and fasteners in the base layers are covered and protected by the overlying layers of gypsum board.
Q3: I understand that even Mold/Moisture Resistant Gypsum Panels should not be used in so-called "wet areas." Can you explain where this product can and cannot be used?
Mold/moisture resistant gypsum panels are excellent for use in high humidity areas and even where an occasional splash of water is expected. Appropriate areas include powder rooms, adjacent to showers or tubs, behind counter areas/base cabinetry where plumbing fixtures are located, and in laundry rooms, mud rooms, etc. However, neither the model codes nor the Tile Council of North America's (TCNA) Handbook allows for the use of these panels behind the tile in the shower or tub area or as a base under the pan or around a swimming pool or sauna. For acceptable materials in wet areas, consult the local code or the TCNA.
Q4: How do I know whether or not to replace gypsum board after it has been submerged in a flood?
You will want to reference GA-231-15 Assessing Water Damage To Gypsum Board. Most notably, gypsum board that has been exposed to sewage or flood waters must be replaced. Levels of bacteria, such as E. coli, can be hundreds of times above safe levels in flood water. Also, hydrocarbons from underground gas storage tanks and fuel leaks from submerged vehicles can be present. Often, the gypsum board will need to be removed anyway to assess the underlying substructure.
