Fire doors hold back smoke and fire by utilising intumescent strips. When the strips are heated to a certain temperature they expand to seal the gap between the door and the frame, preventing smoke from travelling.

How does a fire spread in a building?
If a fire starts, it will spread through any gaps, igniting anything flammable in its path.
