Gypsum board is the name for a family of panel products consisting of a noncombustible core, primarily of gypsum, with a paper surfacing on the face, back and long edges.
The popularity of gypsum wallboard results from a number of factors. First, it takes virtually any decoration-from paint or textures to vinyl and paper laminates. It also lends itself to creative shaping of interior surfaces, allowing the maximum in design flexibility. Gypsum wallboard is an economical alternative to other products. Because it is lightweight, it is easy to handle for speedy installation. With its natural properties, it is durable yet easy to repair. In addition, gypsum wallboard's fire resistance and sound control capabilities further demonstrate its desirability in building systems.
Gypsum wallboard is available with a variety of edge configurations. For easy joint finishing, the tapered edge is preferred to provide a monolithic surface. Where joints will be exposed, square or beveled edges should be considered.
Drywall Technical Data
Fire and sound ratings for building systems utilizing gypsum wallboard are dependent on the core type and thickness of the wallboard, its application in conjunction with the component parts, and the manner in which it is applied.
Tests for fire resistance and sound transmission, performed by independent laboratories, have resulted in specific ratings for walls/partitions; floor/ceiling assemblies; shaftwalls, stairwells and area separation walls; and columns. For maximum fire resistance and sound control, double layer construction is generally recommended since the additional mass further retards heat and noise penetration.
Gypsum wallboard can be installed to both metal and wood framing using nails, screws or adhesives in combination with nails or screws. In many instances, the application will dictate which fastening method is appropriate.
Control joints may be necessary to prevent cracking in the gypsum wallboard facing of drywall systems, especially in areas where structural elements such as slabs, columns or exterior wall can bear directly on non-load bearing partitions. To relieve the stresses which occur as a result of movement induced by changes in moisture, temperature or both, control joints are required in both partitions and ceilings.
Drywall Insulating Properties
For purposes of calculation "U" values, the "C" factor for 1" gypsum board is 1.2; Resistance "R" for 3/8" board is .32; for 1/2" board .45; for 5/8" board .56 and for 1" board .83.
