Hi Karl,
Thanks very much for your question.
The solution can be given with Hilti CFS F FX foam (150 mm thick) and Hilti CFS- B bandage (2 layers) on the accessible side to achieve one side fire rating. The maximum occupancy of the core hole should be 60%. For this, you would need to request for EJ, and we are more than happy to support with this. Could you please email us at NZEngineers@hilti.com to make this request?
Kind Regards,
