A common question amongst building professionals, it is important to understand how penetrations through fire walls should be treated for a variety of different services. On the central wall here we have displayed a multi-service penetration through a fire protected loadbearing wall. While there are several fire penetration solutions available on the market today, this solution has been supplied and tested by TBA Firefly. To ensure compliance of this penetration it was important to first ensure that all timber structure on both faces, and inside the penetration was lined with the sufficient fire protective lining to achieve the desired FRL. One lined the void could be filled with 100mm of high-density non-combustible insulation known as Intubatt, with all service penetrations running through this. Note the different fire stopping requirements of different services. For example, a cable tray requires different treatment to a pex pipe, which in turn requires a different level of treatment to a large diameter PVC pipe.

While this solution is indeed an effective one for zones featuring multiple penetrations, individual penetrations can be treated separately where required. An example of this has been provided at our next audio guide station, in the small room to your right.

Catch you there.
