Plain gypsum tiles with or without perforations are available in plain, painted or laminated types. Painted tiles can be generally used in dry areas where aesthetic requirements are needed.  Laminated tiles can have various benefits according to the type of lamination they have. For instance, PVC laminated tiles can be easily cleaned with a wet towel or tiles with aluminum foil lamination at back are used in grid ceiling applications where there is a possibility of vapor condensation or water drop formation at the back of the tile. Painted tiles are coated with white acrylic, antistatic and antibacterial paint are also produced. The paint used in this type of tile prevents the growth of micro-organisms in the environment and on the tile surface and is a handy and economic option for builders.
