Waldfeucht needs penetration seals that hold the fire-compartment boundary, pass the inspection, get signed off.
An F90-rated wall in Waldfeucht loses its function the moment a cable, pipe or duct passes through it unsealed. Only the approved penetration seal restores that fire resistance — and only if the system used matches the cable density.
The system depends on opening size, occupancy density and wall type.
