Sealing what needs to be sealed in Vlotho and Kreis Herford. Cable seals, pipe stops, combined penetrations. Soft, hard or mortar seals.
An F90-rated wall in Vlotho loses its function the second a cable, pipe or duct passes through it unsealed. Only the tested penetration seal restores that fire resistance — and only if the system used matches the pipe type.
The system depends on opening size, occupancy density and wall type.
