Wall and ceiling penetrations in Waltrop sealed audit-ready, installed to approval, tracked in penetration plans for the consultant's sign-off.
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 direct path for flames and smoke.
