Sealing what needs to be sealed in Nörvenich and Kreis Düren. Cable seals, pipe stops, combined penetrations. Soft, hard or mortar seals.
Penetration seals are approved 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 weak point for flames and smoke.
