Drywall is a construction material commonly used to create interior walls and ceilings. Gypsum, a soft mineral mined from the ground and processed into a powder, is mixed with water and then sandwiched between two sheets of paper and pressed into a smooth, flat panel.

Drywall is a popular choice for interior walls because it is relatively inexpensive and easy to work with. Drywall sheets are installed using screws or nails, and then after the drywall is in place, the seams between the panels are covered with joint compound and tape, and the surface is sanded smooth to create a seamless finish.

Drywall can be finished in a variety of ways, such as painting, wallpapering, or texturing. It also has good soundproofing qualities. Overall, drywall is a versatile and durable material that is extremely efficent to install. It is widely used in the construction industry.
