The C-80 model is characterised by slats with curled ends, which are stiffer and more resistant to wind gusts. Thanks to that fact, it is possible to produce blinds of larger dimensions.
The system is used to create internal and external fire partitions with single and double leaf doors of different fire resistance classes, in a range from 15 minutes to as much as 90 minutes. It is characterised by high thermal and acoustic insulation.
