What is drywall?


Drywall, also known as plasterboard, wallboard, or gypsum board, is a building material used to create walls and ceilings. It consists of a gypsum core sandwiched between two layers of heavy paper. The gypsum, a soft sulfate mineral, provides fire resistance and soundproofing qualities, while the paper layers add strength and durability.

Drywall comes in various thicknesses, typically ranging from 1/4 inch to 5/8 inch, with 1/2 inch being the most common for residential construction. It’s available in different types, such as regular drywall, moisture-resistant drywall (often used in bathrooms and kitchens), and fire-resistant drywall (used in areas where fire protection is crucial).

The installation process involves cutting the drywall sheets to size, attaching them to the framing with screws or nails, and then finishing the seams and screw holes with joint compound and tape. Once sanded and painted, drywall provides a smooth, finished surface for interior walls and ceilings.
