Such sprays swell up when they're exposed to relatively high temperatures and escalation in volume, then, declining density. The swelled spray becomes a shielding material called char that is a bad conductor of heat. This solution provides more time for firefighters to take full charge of the situation from the construction.
If this thing comes in contact with heat, then there's an increase in its quantity from 200 to 300 times that creates an insulating layer that guarantees ignition temperature of material for a while.
