Sealing what needs to be sealed in Schwelm and Kreis Ennepe-Ruhr-Kreis. Cable seals, pipe stops, combined penetrations. Soft, hard or mortar seals.
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 Schwelm.
