What material is commonly used for interior wall surfaces?

Drywall is commonly used for interior wall surfaces due to its numerous advantages. It is made of gypsum board, which is lightweight and easy to handle compared to other materials. This makes installation quicker and more efficient, as it can be easily cut to size and fastened to wood or metal studs. Additionally, drywall provides a smooth surface that can be easily painted or finished to fit the aesthetic needs of various interior designs.

Drywall also offers good fire resistance, which is important in residential and light commercial constructions for safety compliance. Furthermore, it helps with insulation and soundproofing, contributing to a comfortable living or working environment.

Other materials like concrete and plywood may be used in certain applications but are not as common for general interior wall surfaces. Concrete, while durable, is more often seen in structural components or exterior applications. Plywood can be used in some interior applications, but it is typically favored for cabinetry or as sub-flooring rather than as a primary wall surface. Plaster is another alternative for walls, but it’s less common in modern construction due to the labor-intensive process required for application compared to drywall.
