A fire barrier wall, also referred to as a fire partition, is a fire rated wall assembly which is not a fire wall. Typically, the main difference is that a fire barrier wall is not structurally self-sufficient, and does not extend through the roof, or necessarily to the underside of the floor above.Click to see full answer. Accordingly, what is the difference between a fire wall and a fire barrier?Basically, firewalls are thick exterior walls with a higher fire-resistance rating, while fire barriers are interior walls with a lower fire-resistance rating.Subsequently, question is, what are fire barriers in houses? A firewall is a fire-resistant barrier used to prevent the spread of fire for a prescribed period of time. Firewalls are built between or through buildings, structures, or electrical substation transformers, or within an aircraft or vehicle. Similarly, what is a fire rated barrier? The term “fire barrier” refers to a structure that has, at minimum, a one-hour fire resistance rating. Based on the occupancy type for that particular building, the rating can extend to a four-hour rating. By comparison, a “fire partition” must have at least a 30-minute rating for certain types of occupancies.Where are fire barriers required?A minimum rating of 1 hour is mandated for separating control areas located on the first three floor levels above grade plane, whereas minimum 2-hour fire barriers are required for control area separations on all floor levels above the third level.
