feco‘s fecocent system glass walls with F30 fire protection bring natural light into the internal learning zones with a learning lounge, information pool, group corners, workstations and reading areas. At the same time, the transparency also enables teachers in the classrooms to keep an eye on the students in the middle zone. The lower sound insulation of the fire protection glass walls has been economically and constructively compensated by increasing the sound insulation of the fecotür H70 wooden door elements to Rw,P = 40 dB. At the same time, a reduction in reverberation times is achieved through the acoustically-effective slitting of the wall cladding. This significantly improves acoustics and speech intelligibility. Speaking more quietly is less of a strain and reduces the basic noise level. The overall tone in the school is characterised by openness, trust and respect. The first new grammar-school building to be built in Munich for 30 years has been built to passive-house standards. feco glass system partition walls support the open character of the learning landscape.
