  • INTEGRITY enables the door to resist fire without the development of perpendicular through openings wider than 6mm and longer in total than the largest dimension of the door.
  • INSULATION refers to the door’s ability to prevent the transmission of enough heat to raise the mean unexposed face temperature by more than 140°C above the initial temperature.
