- robust, tear-resistant surface to prevent damage during the construction phase, which serves to avoid structure-borne sound bridges
- reduced material thickness of 4 mm for space-saving installation, thus ensuring a clean, visible fire and smoke-tight filling of the component due to the larger intermediate distances from collar to collar.
- easy and quick processing thanks to tool-free quick-release fasteners and suitable molded parts for bends and branches etc. to reduce processing times.
