Velbert needs penetration seals that hold the fire-compartment boundary, pass the inspection, get signed off.
Penetration seals are approved 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.
Fire damper or duct seal — coordinated with the concept, integrated into the duct line.
Vertical penetration — usually box-style, accessible from above, expandable for future cables.
Classic in Velbert stock: cables through F30/F90 wall, mineral wool with coating or board with collars.
Cable and pipe in the same opening — Promat combination, Hilti CFS-CT, Würth fire-stop solution.
Intumescent collar for plastic pipes, mineral wool insulation for steel — system-dependent, per approval, documented in the penetration plan.
