Earlier this year, Independent certification body Branz undertook to test the fire rating properties of Nullifire B747 when used in conjunction with Mineral Fibreboard.
The results of the test were very encouraging. According to the report from Branz,
“It is considered that the Nulifire B747 penetration sealing system, with a nominal 2 mm thick mastic coating to each face and with or without pipe or cable penetrations would achieve the following fire-resistance ratings if tested in accordance with AS 1530.4-2005:”
Further tests regarding different seal configurations, different surfaces (floor, ceiling) were also conducted, with results all indicating the solid performance of the system.
For further information, or to read the report in full (as supplied by Branz to Remedial Building Services) please download the “Mineral Fibre Barrier Fire Rating Test Results” paper here.
