Why Passive Fire Protection Matters

Passive fire protection (PFP) refers to components and systems built into a structure that slow or prevent the spread of fire and smoke without active intervention. These systems maintain compartmentation, protect structural integrity and enhance safe evacuation times. Common PFP elements include fire-resistant walls, fire doors, firestops, intumescent coatings and cavity barriers.
