WHAT IS GYPSUM PLASTERBOARD ?

As per ASTM C11, the gypsum board is “the general name for a family of sheet products consisting essentially of gypsum.”

Also known as plasterboard or drywall, the gypsum board is a technical name given to a plaster-based wall finish that helps in creating light walls. Even though it is an umbrella term, all of its types use gypsum, a non-combustible core, and paper surface covers them.

Once it goes through a joint treatment system, it can create a monolithic structure, built to last.

Gypsum board sizes

You are likely to find gypsum plasterboards of different sizes in the market. Each of these sizes caters to a different purpose. You must choose the optimum size as it will allow you to minimize cost without compromising on quality.

Here are the different size specification for a gypsum plasterboard that you are likely to find -

¼-inch (0.635 cm)

The ¼-inch gypsum plasterboard is a low-cost structure dedicated for use in ceilings, improving existing walls, curved surfaces, and improving sound control. It mainly finds use in home décor.

3/8-inch (0.9525 cm)

The ⅜ -inch gypsum plasterboard finds usage primarily as a face layer for remodelling or repair purposes. These are applied over wood framing and usually in a double-layer format.

½-inch (1.27 cm)

The ½-inch variant is used primarily in single-layer wall systems. It is excellent for soundproofing and fire protection and is more likely to be found in residential buildings.

5/8-inch (1.5875 cm)

The ⅝ -inch variant is one of the thicker versions. It helps in improving resistance, rigidity, and higher fire resistance. These characteristics make them excellent for single-layer and double-layer walls.

¾-inch (1.905 cm) and 1-inch (2.54 cm)

The ¾-inch and the 1-inch variant are used for creating shaft walls, partitions, corridor ceilings, and similar purposes. These are the thickest gypsum plasterboard available and offer the highest resistance.
