Sealing what needs to be sealed in Aachen and Kreis Städteregion Aachen. Cable seals, pipe stops, combined penetrations. Soft, hard or mortar seals.
The right system depends on context. Mineral wool with coating handle most wall penetrations in Aachen stock; fire boards go in for when frequent re-cabling is expected. Combined cable+pipe penetrations need a system that's approved for both.
