Fire Stopping

Passive Fire Protection is the use of fire-resistance rated materials in walls and floors to prevent or slow down the spread of fire.

As opposed to active fire protection measures, passive fire protection means do not typically require electric or electronic activation or a degree of motion. Firewalls not only have a rating, they are also designed to sub-divide buildings such that if a fire occurs on one side, this will not affect the other side.
