Firestop solutions for pipe penetrations

We offer firestop solutions for all common piping applications including heating, plumbing, air conditioning and cooling systems

Public awareness of fire safety in buildings has surged. Building owners and occupants alike are now demanding passive fire protection – that is, features within the structure to help prevent flames, heat and smoke from spreading – which can help save lives and minimize damage if fire breaks out. Pipe penetration assemblies are critical areas for firestopping. Even these seemingly small gaps in fire-rated walls and floors are enough for smoke and toxic gasses to spread through. To maintain the fire resistance of walls and floors, it is essential that every opening is sealed using a well-designed and installed firestop system.

Despite its undeniable importance, firestopping is still often treated as an afterthought. Cost overruns, strained budgets and scheduling conflicts between trades on-site are virtually unavoidable if fire protection is neglected until the final project phases.


Labor-saving, one-step, cast-in firestop solutions

Firestop cast-in device

The CP 680/CFS-CID (cast-in device) is a game-changer for firestopping pipe floor penetrations. It is a one-step, cast-in solution for both plastic and metal pipes – a productivity booster, a true space saver and easier to inspect. By planning and specifying cast-in devices before casting the slabs, firestop is shifted from the last step to the first. No coring and drilling are required, and on-site trade coordination becomes much simpler. The integrated smoke gasket in the device makes caulking unnecessary.  

The firestop performance of pre-formed devices doesn’t rely on the installer’s skills. The risk of failed inspections due to faulty installation is therefore significantly reduced.

The systems are available for both flat concrete and composite metal deck slabs.
