The new nursing school in Ettelbrück, Luxembourg, can accommodate 430 student nurses. All the classrooms and corridors are equipped with Lignature surface elements, Acoustics type 3.1. The underside has a strip perforation in a 40 × 40 mm grid, while the hole diameter is 20 mm. The surfaces are designed in visible quality towards the inside of the room and are provided with light-protection. In this way the elements retain their light colour.
