Cable and pipe penetrations for walls and ceilings in Olpe — approved, tested, documented. Promat, Hilti, Würth · S30 to S90 · existing stock, new build, retrofit.
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.
Vertical penetration — usually box-style, accessible from above, expandable for future cables.
