Niederkassel needs penetration seals that hold the fire-compartment boundary, pass the inspection, get signed off.
Penetration seals are approved closures of wall and ceiling openings. They preserve the fire compartment 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.
