What is FireBlock insulating foam anyway?


The purpose of Dow Great Stuff FireBlock insulating foam is to slow the spreading of smoke and fire.

It forms a barrier to cut off concealed draft openings between floors, a top story and an attic or roof, and between walls.

Fireblock helps to avoid a chimney effect that would allow smoke and flames to spread to adjacent walls and floor spaces. The goal is to slow the spread of smoke and fire to allow time for occupants to evacuate a structure.
