Abstract (en)
The board (1) has a lower surface provided with a fleece layer and a layer of acoustic plaster, where a set of strip-like hole-free regions (3) is provided within the board. A set of hole surface portions is greater than 30 percentage of the board. The regions run parallel to each other at regular distances. The regions run adjacent to each longitudinal edge of the board. A foil and/or a fleece are applied on a side turned away from a visible side. Longitudinal front sides and transverse front sides with right-angled edges are changed into upper and lower surfaces. An independent claim is also included for a method for manufacturing a suspended ceiling under utilization of a perforated gypsum board.
