Function :

Intumescents assume two important functions in the fire door: 

  1. sealing of joints to avoid the escape of hot gas due to the overpressure in the furnace
  2. fixation of the door blank weakened by burning to the frame

Choice and Installation :

The choice and the structure of the material with the suitable characteristics is of great importance. 

Under certain circumstances intumescents can be fitted through frame and edges either open or covered.
