Robust, tear-resistant surface to prevent damage during the construction phase, this serves to avoid structure-borne sound bridges.
Reduced material thickness of 13 mm for space-saving installation to ensure a clean, visible fire and smoke-tight filling of the component through the resulting larger intermediate distances from sleeve to sleeve.
Easy and quick processing due to tool-free quick-release fastener to reduce processing times.
Internal sliding film to ensure the displaceability of the sleeves on the pipe for quick assembly and to avoid operating noise.
Special fleece, building material class according to DIN 4102-1: A1
Special fleece, melting point according to DIN 4102-11: >1000°C
