Advanced Protection for Critical Door Hardware

FlexiFire is a high-performance intumescent material developed to protect ironmongery within a fire door assembly. When exposed to heat, the graphite core activates at 180°C, expanding to insulate and seal.

Engineered for use behind hinges, locks, latches and door closers, FlexiFire strengthens weak points within the fire door installation, helping maintain fire safety performance under BS EN test conditions.
