The execution must be carried out according to ABZ-19.17-2010 of DIBt or VKF No. 23830. The proper execution must be certified by the contractor with a certificate of conformity after completion of the work. Each pipe seal must be permanently marked with the sign included in the scope of delivery. The sign must be attached to the component next to the pipe seal.
When offering equivalent, alternative products, the following essential product features must be observed and documented to the client in writing with manufacturer's evidence:
- robust, tear-resistant surface to prevent damage during the construction phase, which helps avoid acoustic bridges
- reduced material thickness 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 fastener to reduce processing times.
