Wall and ceiling penetrations in Anröchte sealed audit-ready, installed to approval, tracked in penetration plans for the consultant's sign-off.
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.
The system depends on opening size, occupancy density and wall type.
Fire damper or duct seal — coordinated with the concept, integrated into the duct line.
