Fire Barrier Systems

Fire Barrier Systems (also known as Cavity Barriers) provide protection against fire and smoke in hidden areas. They are essential to prevent the rapid spread of fire in concealed spaces within a building and effectively prevent the spread of fire and smoke within unseen roof and ceiling voids.

Unlike exterior firewalls, fire barriers are walls built within a structure. They can either extend from the floor to the roof or from one floor to the ceiling of the floor above. These subdividers can cover hidden spaces and are supported by floors, columns, roofs, and other interior structures.

Fire barriers can resist fire for up to three hours as long as the supporting structures have the same level of fire resistance. This design can allow occupants to safely evacuate the building while containing the fire to the smallest possible area.

This can protect the building both from fire and smoke damage, as well as water damage from sprinklers. A one-way fire barrier withstands flames from one side only. Two can be placed together to block fire from both sides.
