Kalkar 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 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 weak point for flames and smoke.
We combine Promat, Hilti and Würth — system-open, brand-neutral in Kalkar.
