Cable and pipe penetrations for walls and ceilings in Stolberg (Rheinland) — approved, tested, documented. Promat, Hilti, Würth · S30 to S90 · existing stock, new build, retrofit.
Penetration seals are DIN-validated closures of wall and ceiling openings. They prevent fire and smoke spread for the same duration the wall itself is rated for — 30, 60 or 90 minutes. Without a seal, every cable, pipe or duct that crosses the wall becomes a direct path for flames and smoke.
The system depends on opening size, occupancy density and wall type.
