Fire Stopping
Fire safety is one of the most important aspects of infrastructure design and operation. Every pipe or cable passing through a wall, floor or bulkhead is a potential weak point where fire and smoke can spread. To protect people and assets, those penetrations must be sealed with solutions proven to resist fire for hours, not minutes.
Fire Stopping
CSD’s fire stopping systems are fully tested and certified to the highest international standards. Our NOFIRNO®, SLIPSIL® and FYLLOFOAM® products provide up to four hours of fire resistance while also protecting against water, gas and smoke ingress.

- Low-maintenance, long-life solutions trusted in nuclear, naval and civil sectors

“CSD Technical Services delivered the water, and gastight sealing works to a high standard across our control room and DNO substation. Their support contributed effectively to our wider climate action plan, including the installation of a new solar farm and battery storage system. We were very satisfied with the work and will be considering CSD for future projects.”
