Easy Passive Fire Stopping for
Cross Laminated Timber Walls

Timber walls have undergone a modern renaissance in the construction industry in a new form of thick cross-laminated timber beams called CLT or mass timber. These sustainably sourced materials are being used in the Australian building industry due to their environmental sustainability, acoustic and fire-resistant properties. This page lists the tested passive fire penetration systems currently available to maintain the fire resistance level (FRL) of service penetrations through these timber wall systems. 


We have a wide range of resources available for every product and system to ensure that you’re choosing the right fire stopping solution for your needs.

FRL Tables, installation instructions, benefits, applications, and more are all available in our comprehensive manuals, for all systems and products.

Passive Fire Stopping Systems for
Cross Laminated Timber Walls

We can currently offer cavity barrier solutions for use at the slab edge with timber constructions as shown below, to comply with C1.13 of the NCC. We also have a range of fire stopping solutions for service penetrations through timber walls, this currently only applies to certain brands of CLT construction, however there is always more testing being done at Trafalgar– contact the technical team for assistance with fire engineering and site specific fire testing requirements ([email protected]).
