Sealing what needs to be sealed in Krefeld and Kreis Krefeld, Stadt. Cable seals, pipe stops, combined penetrations. Soft, hard or mortar seals.
Every wall penetration in Krefeld that crosses a fire-compartment boundary needs documentation: approval number. Consultants check this every year. Insurers reference it at renewal. A missing seal is the kind of finding that gets cited in damage reports.
The system depends on opening size, occupancy density and wall type.
