A workroom partition divides a workroom interior of a workroom and a workroom surroundings. The workroom is provided with a laser processing device. The workroom partition includes on its inner side facing the laser processing device, a laser beam reflector formed from pre-fabricated reflective sheet of material having a grained reflective surface structure that faces the laser processing device, by means of which the majority of laser radiation incident on the laser beam reflector and originating from the laser processing device is diffusely reflectable.
