Plaster board plate

摘要

The plaster board plate has a gypsum layer (13) arranged between a lower board (11) and an upper board (12). At least one of the two board layers (11,12) has a structured indented surface (15) which is produced before the gypsum layer sets. The indented surface can have irregular or regular indentations and/or protrusions formed in the board surface (16). Independent claims are included for a manufacturing process using an imprinting device to produce structured surface.
