Where are Fire Barriers used and why?
1. In all floor and wall joints that occur in fire rated locations ad potentially compromise compartment zones. The Fire barrier is often located beneath the EJS. 2. To prevent fire and smoke from penetrating an expansion joint opening for the specified rating period, i.e. 2 hours. 3. In some cases, to prevent temperature on the cold side of an expansion joint opening from rising above a predetermined rate for the specified rating period, i.e. 2 hours. The “cold side” of an expansion joint opening refers to the area within a structure adjacent to, or opposite the area where a fire or smoke source is located.
