The construction industry commonly uses gypsum because of its resistance to heat. The most common end-product is the gypsum board (drywall) or plaster board to produce false ceilings.

To make gypsum board, mix the calcined gypsum with water and additives to form slurry. Then feed the mixture between stacked papers on a gypsum board making machine. The mixture recrystallizes and bonds with the paper. It must dry to remove water before adding finishing touches such as coating and painting. Aesthetically, false ceilings are more appealing, and it’s also possible to install lights on them. This type of ceiling doesn’t conduct heat and prevents fire. They are good sound insulators and durable depending on how they’re managed.
