When offering equivalent, alternative products, the following essential product features must be observed and documented in writing to the client by means of manufacturer's proofs:
robust, tear-resistant surface to prevent damage during the construction phase, this serves to avoid sound bridges
reduced material thickness of 13 mm for space-saving installation, thus ensuring a clean, visible fire and smoke gas-tight filling of the component due to the larger intermediate distances from sleeve to sleeve.
simple and quick processing due to tool-free quick-release fastener to reduce processing times.
Inner sliding film to ensure the sleeve's displaceability on the pipe for quick installation and to prevent operating noise.
