Abstract (en)
The method involves producing a carrier structure (2) and laminating the carrier structure with a plastic coating (3). The plastic coating is provided with a micro perforation using laser light, after the lamination process. The micro-perforation is produced using a porous screen. The layers lying between the plastic coating and the carrier structure are perforated using the laser light. An independent claim is also included for an acoustic building board for covering the room surfaces such as wall and cover panels.
