Fitherm IG is developed for a wide range of applications where an intumescent material is necessary to maintain the system integrity and insulation in case of fire. These systems are for example:

  • fire doors and glazing systems
  • fire safes
  • special containers
Fitherm IG can be stored under normal room conditions. During handling and processing the wearing of protective gloves is recommended.

Fitherm® IG can be customised to special forms for multiple applications.
