Würselen 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 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 breach for flames and smoke.
We combine Promat, Hilti and Würth — system-open, brand-neutral in Würselen.
Intumescent collar for plastic pipes, mineral wool insulation for steel — system-dependent, per approval, documented in the penetration plan.
Classic in Würselen stock: cables through F30/F90 wall, mineral wool with coating or board with collars.
