Astro FlexiFire is a graphite-based intumescent material that offers high levels of expansion and insulation, preventing heat transfer on rebated hardware. All ironmongery installed on a fire door must be fitted without compromising the integrity of the complete fire door assembly. This is of particular importance where ironmongery is rebated into the doorset such as hinges, locks, latches.

As the material reaches its activation temperature of 180°, the intercalated graphite particles expand many times their original volume. Astro FlexiFire is an ultra thin and flexible high performance graphite based intumescent sheet. At 0.8mm Astro FlexiFire offers high levels of expansion and insulation preventing heat transfer on ironmongery rebated into timber doorsets.

Flexible and fully customisable the Astro FlexiFire is suitable for use on all types of fire rated hardware. For instance on Door Hinges, Door Locks and Latches, Flush Bolts and Door Controls. Please check that your hardware test evidence is compatible with Astro FlexiFire prior to installation.
