Eschweiler needs penetration seals that hold the fire-compartment boundary, pass the inspection, get signed off.
Penetration seals are DIN-validated 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 direct path for flames and smoke.
The system depends on opening size, occupancy density and wall type.
Cable and pipe in the same opening — Promat combination, Hilti CFS-CT, Würth fire-stop solution.
Vertical penetration — usually box-style, accessible from above, expandable for future cables.
Fire damper or duct seal — coordinated with the concept, integrated into the duct line.
Intumescent collar for plastic pipes, mineral wool insulation for steel — system-dependent, per approval, documented in the penetration plan. Documented in the property log in Eschweiler.
