Companies in the Wallboard & Plasterboard Manufacturing industry produce gypsum-based plasterboard and other related products. These products are used in the construction industry for interior walls and ceilings. The manufacturing process involves mixing gypsum, water, and additives to create a slurry, which is then poured onto a layer of paper and sandwiched between two more layers of paper. The resulting board is then cut to size and dried in a kiln. Wallboard and plasterboard are popular due to their fire-resistant and soundproofing properties, as well as their ease of installation.
