plasterboard

Imagine building the inside walls of a house-you would not start with bricks. Instead, builders often use plasterboard (also called drywall or gypsum board) to make smooth surfaces for walls and ceilings quickly. It is a large, fairly stiff sheet made from gypsum, a soft mineral, covered with heavy paper on both sides.

Plasterboard is common in modern buildings-homes, offices, and schools. In older buildings, people often spread wet plaster over thin strips of wood called lath. Plasterboard replaces that slower method. It can break or dent if handled badly, so it is usually fixed to wooden or metal frames and then finished with joint compound ("mud") and paint. When it is installed well, it gives a neat, smooth interior finish.

Plasterboard is a widely used building material for creating interior walls and ceilings. It consists of large sheets made of gypsum—a soft sulfate mineral often found in sedimentary rock—sandwiched between thick paper layers. Think of it as a prefabricated wall surface, ready to be installed instead of applying plaster manually over wooden lath. This makes construction much faster and more cost-effective.

The term "plasterboard" is the standard name in British English, while "drywall" or "gypsum board" are the preferred terms in North America. All three refer to the same material. Historically, walls were created by applying wet plaster over wooden strips (lath). Plasterboard revolutionized construction because it eliminated the need for this time-consuming process. It is attached to timber or metal studs, and then the joints between boards are covered with a joint compound—often called "mud"—which is sanded smooth before painting.

Plasterboard isn't just about convenience; it also offers benefits like fire resistance and sound insulation, depending on its composition. Different types of plasterboard exist for specific purposes: moisture-resistant board for bathrooms, fire-rated board for safety, and even acoustic board to reduce noise transmission. So, the next time you see a smooth interior wall, remember the unsung hero behind it—the humble yet essential plasterboard!
