Carpentry & Building ConstructionChapter 32: Wall & Ceiling SurfacesChapter SummariesSection 32.1 Drywall Drywall is made of a gypsum core covered with special paper. It comes in three basic types: standard, fire code, and moisture resistant. Joint compound and tape are used to fill joints. Panels can be installed vertically or horizontally. Installation differs for wood or steel framing. Section 32.2 Plaster Plaster must dry before other work can progress. This can slow the construction schedule. Plaster is applied over gypsum or metal lath in two or more layers. It can be given a smooth or textured finish. Section 32.3 Suspended & Acoustical Ceilings Suspended ceilings consist of panels held in place by a metal or plastic grid. They cover joists, pipes, and wiring. They are also used to lower a ceiling or to provide sound insulation. |  |
