What a penetration seal achieves.

Penetration seals are DIN-validated closures of wall and ceiling openings. They hold the rated wall's integrity 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.
