FyreFLEX Insulation and Performance:

FyreFLEX sealant can achieve an FRL up to -/240/120 on small bundles of cables in certain fire barriers, however larger cables and metallic pipes will reduce the insulation rating (i.e. increase in heat rise) under fire conditions. When this occurs, TWrap is required to be wrapped around the services for a certain length to achieve better insulation performance. For more information, refer to the Technical Manuals or call the Trafalgar Technical team on 1800 888 714.
