Our range of intumescent products are made from a graphite-based material which offers high levels of expansion and insulation, preventing heat transfer on rebated hardware. As the material reaches activation temperature of 180 degrees, it expands to many times its original volume. To be used with corresponding locks, latches and hinges for fire door compliance.
