It helps stopping smoke and fire from spreading from the gaps in the edges of door shutter & frame joints, locks, handles, etc.

The edges of a door are one of the most vulnerable when fire strikes, so intumescent strip is extremely important. Two main types are available - Fire Only or Fire & Smoke.
