Sealing what needs to be sealed in Marienheide and Kreis Oberbergischer Kreis. Cable seals, pipe stops, combined penetrations. Soft, hard or mortar seals.
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 weak point for flames and smoke.
The system depends on opening size, occupancy density and wall type.
