Drywall is a construction material used to create walls and ceilings. It’s also used to create many design features, including eaves, arches and other architectural specialties.
It’s quick and easy to install, incredibly durable, and requires only simple repairs when damaged. In the commercial building world, drywall is used to wrap columns to conceal steel beams and is an easy and inexpensive way to top off masonry walls above 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.
One of the things most homeowners appreciate is the low price of drywall. And so not all drywall is the best quality ever. Drywall finish is the best for durable results. What is drywall made of? The material consists of two sheets that are usually made of paper and sandwich gypsum. Most panels are found in 4 x 8 ft. and in several thicknesses.
