drywall, also called wallboard, any of various large rigid sheets of finishing material used in drywall construction to face the interior walls of dwellings and other buildings. Drywall construction is the application of walls without the use of mortar or plaster.
Why is drywall used?
Drywall is a construction material used to create walls and ceilings. Drywall is also used to add fire resistance at walls and ceilings, containing the spread of fire so people can evacuate safely during an emergency. Before drywall became widely used, building interiors were made of plaster.
Why is drywall used instead of plywood?
Drywall is more fire resistant than plywood – Often people are worried about the fire resistance in their home. This is why drywall is chosen. Drywall is much better than plywood when it comes to being fire resistant as it does not burn as fast or catch on fire as easily.
When was drywall commonly used?
In the mid-20th century, drywall construction became prevalent in North America as a time- and labor-saving alternative to traditional lath and plaster.
Is drywall used in houses?
Gypsum is noncombustible, and compared to other wall materials, like solid wood and plaster, gypsum boards are much lighter and cheaper. As a result, drywall is popular in homes across the U.S.: According to the Gypsum Association, more than 20 billion square feet of drywall is manufactured each year in North America.
Why is drywall used in America?
The primary advantage of drywall over plaster is labor savings — you can install drywall in considerably less time than plaster, and it makes for a very smooth wall. In addition, if you use 5/8″ thickness or greater, the walls you build are fire resistant — even over wood studs.
Is drywall better than plaster?
For one thing, plaster is by nature a more durable finish than drywall, even high-level drywall finishes. In addition, plaster outperforms drywall in a number of key areas, including insulation, soundproofing, and fireproofing. One additional point in plaster’s favor is that by nature, mold can’t grow in plaster.
Does drywall insulate?
Drywall is considered a suitable construction material for interior walls, but its primary purpose is not to insulate. To make a significant difference in heat flow transfer, you must include insulation along with the drywall installation.
Does drywall add strength?
A sheet of drywall, like a sheet of plywood, is stronger along its long axis. So put that knowledge to good use.

Is drywall cheaper than brick?
Cost effectiveness – The material cost of drywalls is almost similar to that of using brick and mortar. However, because of the speed with which drywalls are installed, labour costs when compared to brick building may be substantially lower, which makes drywalling a highly cost-effective building method. 4.
Can you replace drywall with plywood?
You can use plywood instead of drywall for walls and ceilings. Plywood weighs less, and it’s also stronger and more damage-resistant than drywall. Construction-grade plywood is more expensive, though, and it might not meet local building codes as it isn’t as soundproof or fireproof as drywall.
