And based on the type of drywall, it can also provide resistance to abrasion, impact, mold and mildew, while reducing the transmission of sound and providing enhanced indoor air quality. Today’s modern drywall - which consists of a gypsum core sandwiched between two layers of paper - simplifies the installation process. Creating plaster walls required several coats to be applied, with a long drying time prior to final decoration. Drywall installation is the stage in which a residential or commercial building stops looking like a construction site and starts looking more like a livable and functional space.īefore drywall became the widely used product it is today, interior walls and ceilings were made by placing layers of wet plaster over wooden strips (called “laths”). Following the standard approach to constructing interior walls and ceilings, installing drywall represents a key step in moving from the framing, plumbing, wiring and insulating stages of construction to the finishing stages of the project.
