Need flexibility, space optimisation and the natural flow of light?

Variflex® mobile acoustic GLASS partitions permit flexible room layouts and subdivide classrooms, meeting venues or offices, only with an overhead track. Two or more areas can be used simultaneously without disrupting each other or a large area can be created with the individual elements being parked neatly to one side or into a niche. An acoustic rating range from DnTw = 40dB to 48dB is available (Please note: the updated acoustic sound level testing method is an in-situ measurement of the Standardised Level Difference according to ISO 162283-1 2014, analysed according to weighted Standardised Level Difference, DnTw, according to ISO 717-1).
