  • May not use this picture at all
  • Buying time for Fire departments and to get people out of building
  • Focus on head of wall Joints
  • Will find in the XHBN Section of UL directory vol 2A this covers all joints. May want to take them to web site.
  • The MGM and one and first all Gave birth to head-of-wall joints
  • All addresses firestoping
  • 713-1Look for lable;;; also mentioned on caulk tube.;;; 713-2 need be D listing Dynamic;;;;
  • Compression and Extension
  • Need to look at movement charictic Mechanical jonts do not depend on caulks and sprays.
  • Different components
  • Mineral Wool is weak link and the Caulk
  • The most current listings you can pull up on this web site. They change all the time. Mark can you find a different picture here.
  • S may be used but it has not been tested for cycle tests;;;; The first numbers of the system do mean something.
  • The most current listings you can pull up on this web site. They change all the time. Mark can you find a different picture here.

    25. 27. NON CODE COMPLIANT HEAD-OF-WALL JOINT
    26. 29. Listed and Tested Head-of-Wall Assemblies View some details that will perform structurally when exposed to fire.
    27. 33. SMOKE BARRIERS <ul><li>Section 713. 6 of the IBC requires an L rating of 5 or less. </li></ul><ul><li>Joints systems in these assemblies needs to be designed and constructed to restrict the movement of smoke. The type of rating used is an L Rating which is a measurement of air leakage rate through a fire resistive joint system or penetration. </li></ul>
    28. 34. Plans Examiners and Inspectors
    29. 35. PLANS EXAMINERS <ul><li>As part of your plan review, are you checking the below items as it relates to the Head-of-wall joints: </li></ul><ul><li>Determine the rate of building deflection ( range of motion) </li></ul><ul><li>Identify the tested and listed head-of-wall system for every interior non load baring partition. </li></ul>
    30. 36. RECOMMENDED CORRECTION NOTICE <ul><li>Deflection and firestop tracks are required to be installed with an approved joint system per section 713 of the IBC. The assemblies need to be designed to allow head-of-wall joints to compress and extend with movement of structure above while maintaining the fire-rating of the assemblies. </li></ul><ul><li>Please clarify building deflection to determine movement capabilities of assembly and identify listed assemblies for these ceiling runners. </li></ul>
    31. 37. HEAD-OF-WALL INSPECTION <ul><li>IBC CODE REQUIREMENT </li></ul><ul><li>Section 109.3.6 </li></ul><ul><li>Fire-resistant penetrations. Protection of joints and penetrations in fire-resistance-rated assemblies shall not be concealed from view until inspected and approved </li></ul>
    32. 38. Field Inspection <ul><li>If the deflection rate is under (1) one inch you may not have to observe the top track until the final inspection. If a mechanical joint is required you will need to: </li></ul><ul><li>Be provided with the UL listed assembly as approved on the plans. </li></ul><ul><li>Determine all interior non load baring partitions that require a fire rating and inspect during framing inspection. </li></ul><ul><li>Observe the ceiling runner for the U.L label that is located on the side of the mechanical joint system. </li></ul>
    33. 40. Engineering Judgments <ul><li>Sources: </li></ul><ul><li>Third Party Labs (UL) </li></ul><ul><li>Fire Protection Engineer </li></ul><ul><li>Professional Engineer </li></ul><ul><li>Manufacturer </li></ul><ul><li>Only used when tested systems are not available . The EJ’s Must be based on sound engineering practice and knowledge of both field application and capabilities of system components </li></ul>
