Wilnsdorf needs penetration seals that hold the fire-compartment boundary, pass the inspection, get signed off.
The right system depends on context. Mineral wool with coating handle most wall penetrations in Wilnsdorf stock; fire boards go in for when frequent re-cabling is expected. Combined cable+pipe penetrations need a system that's documented in the penetration plan.
The system depends on opening size, occupancy density and wall type.
