Through the special press-joints mounting brackets a consistent surface connection of Küffner aluminium panels emerges. Six-metre long transport size, a simple cut on-site and a practice-oriented joining technique facilitate a simple mounting. The Küffner system comprises solutions for inspection opening, lighting devices, corner, end and beginning profiles. In addition, all panels can be executed with hole or slit-shaped openings of defined surfaces for the improvement of spatial acoustics or ventilation, and also as cooling ceiling or heating ceiling versions.
