Intumescent Ironmongery Protection. 

​​​​​​​

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 and concealed door closers. 

FlexiFire is an ultra thing flexable high performance intumescent sheet. Available from 0.8 to 2mm thick. FlexiFire offers high levels of expansion and insulation preventing heat transfer on ironmongery rebated into timber doorsets.
