Fire protection is usually split into two families. Passive protection — compartmentation, fire-rated materials, intumescent coatings — is built into the structure and works without activation. Active protection — sprinklers, gaseous systems, detection — senses a condition and responds.
Two roles, one goal
- Passive: slows spread and buys time; always present, no trigger.
- Active: detects and suppresses; requires sensing and delivery.
Material-level response sits between the two: it is built into the material like passive protection, but it responds to a trigger — heat — like active protection. The response is local and does not depend on room-level detection or plumbing.
A different layer of protection — engineered into the material, triggered by heat, acting where the event begins.
It is designed to complement, not replace, code-required systems.
