2 Saving Lives and Property Through Fire and Smoke Containment ©2004 IFC Fire Protection of Construction Joints

3 Saving Lives and Property Through Fire and Smoke Containment ©2004 IFC Answer: Because Joints Move and may present a weakness in fire containment Question: Why So Much Concern About Fire-Resistive Construction Joints?

4 Saving Lives and Property Through Fire and Smoke Containment ©2004 IFC Where Do I Find These Applications?

5 Saving Lives and Property Through Fire and Smoke Containment ©2004 IFC Construction Joint Terminology A A – Overall depth of concrete floor assembly B – Flute depth C – Joint width D – Minimum concrete depth E - Valley B C D E

6 Saving Lives and Property Through Fire and Smoke Containment ©2004 IFC Assembly Rating Movement Nominal Joint Width Extension Compression Percent (%) Extension / Compression Mineral Wool Compression Sealant Depth Construction Joint Terminology

7 Saving Lives and Property Through Fire and Smoke Containment ©2004 IFC Tests for Fire Resistance of Building Joint Systems Standards:ASTM E 1966 UL 2079 Test Items:Building Joint Systems Including: floor-to-floor floor-to-wall head-of-wall wall-to-wall Report:Fire rating in hours, i.e., 1, 2, 3 or 4 hours

8 Saving Lives and Property Through Fire and Smoke Containment ©2004 IFC Tests for Fire Resistance of Building Joint Systems ASTM E 1966 & UL 2079 All Model Building Codes Now Require Cycling per ASTM E 1399 Time temperature curve (ASTM E 119) Must meet Assembly Rating (T Rating) criteria –250° F + ambient average (ASTM E 1966) –Any 1 thermocouple over 325° F + initial temp (UL 2079) Hose stream applicable to walls and wall tops

9 Saving Lives and Property Through Fire and Smoke Containment ©2004 IFC Building Construction and Materials Fire Tests: Joint Systems (ASTM E1966, UL 2079) ASTM E 119 UL 263 NFPA 251 Fire Inside Through-Penetration Firestop: (ASTM E 814, UL 1479)
