It is critical that any firestopping sealant that is used on CPVC products is checked for both chemical compatibility, and of course like all firestopping products, evidence that the product has been tested in accordance with AS1530.4:2014 & AS4072.1-2005 and meets the required fire resistance level for the desired application.

The very nature to how the CLT slowly chars away adds extra consideration for firestopping systems as these treatments are often mounted to the wall in a way that they could fall off as the timber burns away.

Specifying multi-service bundles which have been tested for compatibility with acoustic lagging and thermal insulation can help simplify compliance.

In the event of a seismic event, will the specified passive fire treatment need to remain in place ready to work in the event of a fire? Or is the treatment designed to be repaired if it has cracked or moved in the event of a seismic event?

We have all heard the terms Fire Rated, Fire Resistant and Fire Retardant. But do they all mean the same thing?
