Cable and pipe penetrations for walls and ceilings in Sendenhorst — approved, tested, documented. Promat, Hilti, Würth · S30 to S90 · existing stock, new build, retrofit.
An F90-rated wall in Sendenhorst loses its function the moment 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 wall construction.
