Büren needs penetration seals that hold the fire-compartment boundary, pass the inspection, get signed off.
Penetration seals are building-authority-tested 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 breach for flames and smoke.
The system depends on opening size, occupancy density and wall type.
Take over multi-brand stock in Büren, consolidate in the penetration plan, prepare for consultant sign-off.
