3 BALANCED APPROACH TO FIRE PROTECTION We cannot rely on any single action or safeguard to keep people safe

4 PARTITION SCHEDULE FIRE RATED ASSEMBLIES ASSEMBLY TYPE A ONE LAYER GYP EACH SIDE. UL DESIGN U465 WHERE FIRE RATING SCHEDULED ASSEMBLY TYPE B ONE LAYER GYP ONE SIDE, TWO LAYERS OTHER SIDE. UL DESIGN U448 WHERE 1 HR FIRE RATING SCHEDULED

5 FIRESTOP RESTORES THE INTEGRITY OF FIRE RATED ASSEMBLIES Through penetrations Joints Membrane penetrations Firestop is a fire protection system made of various components used to seal openings and joints in fire-resistance rated wall and/or floor assemblies.

6 FIRESTOPPING IS NOT NEW: REQUIRED BY ALL CURRENT AND LEGACY CODES

7 INTERNATIONAL BUILDING CODE Code Section Category Referenced Test Standard Through Penetrations (Walls) ASTM E814 or UL Through Penetrations (Floors) ASTM E814 or UL Membrane Penetrations ASTM E814 or UL Fire Resistant Joints Systems ASTM E1966 or UL Exterior Curtain Wall/Floor Intersection (Perimeter Joint) ASTM E Special Inspections of Fire Resistant Penetration & Joints Penetrations: ASTM E 2174 Joints: ASTM 2393 Understanding the testing process is key to designing fire resistant systems

9 FIRESTOP SYSTEMS IDENTIFY EACH COMPONENT REQUIRED TO ACHIEVE THE DESIRED FIRE RATING Fire rated assembly construction components Acceptable size and type of penetrating items Firestop materials needed to fill voids Specified limits for size of opening, annular space, etc. Each tested system is given their own Firestop System Number

10 MANY FACTORS AFFECT FIRE PERFORMANCE AND EACH ARE PARAMETERS IN THE TESTING OF A SYSTEM Through Penetrations Size and type of penetrating item(s) Size and shape of opening Desired fire rating (hrs.) Floor or wall construction type and thickness Annular space Firestop products used Joint width Joints Desired assembly rating (hrs.) Floor or wall construction type and thickness Movement requirements (%) Stud width for gypsum walls Firestop products used Once a tested firestop system has achieved the desired fire ratings, then a Firestop System is issued (published) by the testing agency

11 INTERNATIONAL BUILDING CODE Code Section Category Referenced Test Standard Through Penetrations (Walls) ASTM E814 or UL Through Penetrations (Floors) ASTM E814 or UL Membrane Penetrations ASTM E814 or UL Fire Resistant Joints Systems ASTM E1966 or UL Exterior Curtain Wall/Floor Intersection (Perimeter Joint) ASTM E2307 Understanding the testing process is key to designing fire resistant systems

12 IBC : MEMBRANE PENETRATIONS FIRESTOP SYSTEMS TESTED TO ASTM E 814 / UL 1479 Recessed fixtures shall be installed such that the required fire resistance will not be reduced. Sum total area of openings does not exceed 100 square inches for any 100 sq. ft. of wall Steel electrical boxes on opposite sides of wall must be separated by a horizontal distance > 24 inches min. separation Steel boxes outside these parameters must be protected

13 MEMBRANE PENETRATIONS REQUIRE SPECIAL CONSIDERATION DURING THE DESIGN PHASE TO ENSURE PROPER FIRE CONTAINMENT Outlet Boxes Icemaker Boxes Washer/Dryer Boxes Putty pads provide simple protection solution for electrical boxes, but icemaker boxes require a more complex system.

14 INTERNATIONAL BUILDING CODE Code Section Category Referenced Test Standard Through Penetrations (Walls) ASTM E814 or UL Through Penetrations (Floors) ASTM E814 or UL Membrane Penetrations ASTM E814 or UL Fire Resistant Joints Systems ASTM E1966 or UL Exterior Curtain Wall/Floor Intersection (Perimeter Joint) ASTM E2307 Understanding the testing process is key to designing fire resistant systems

15 JOINT FIRESTOP SYSTEMS TESTED TO ASTM-E / UL 2079 Assembly Rating Measures both fire and temperature ratings on the non-fireside of the joint. Hose stream only required for top-of-wall and wall-to-wall joints. Joint undergoes cyclic testing prior to fire testing. L-Rating (optional) Amount of air leakage through firestop system at ambient and 400 F Indicates ability to restrict movement of smoke Measured in CFM/lin. ft.

16 FIRE RESISTANT JOINT APPLICATIONS

17 ASTM E1966 / UL2079: FIRE RESISTANT JOINTS MUST ENDURE CYCLIC TESTING PRIOR TO EXPOSURE TO FIRE Cyclic testing simulates the contraction and expansion of the joint

18 INTERNATIONAL BUILDING CODE Code Section Category Referenced Test Standard Through Penetrations (Walls) ASTM E814 or UL Through Penetrations (Floors) ASTM E814 or UL Membrane Penetrations ASTM E814 or UL Fire Resistant Joints Systems ASTM E1966 or UL Exterior Curtain Wall/Floor Intersection (Perimeter Joint) ASTM E2307 Understanding the testing process is key to designing fire resistant systems

19 IBC 715.4: PERIMETER FIRE BARRIER (JOINT) EXTENDS THE FIRE RATING OF THE FLOOR TO THE EXTERIOR WALL Perimeter fire barrier testing is unique, with fire exposure from both below and from outside

20 KEY ELEMENTS TO PERIMETER FIRE BARRIER SYSTEM 1. Stiffener angle at floor line 2. Insulation board Mechanical attachment of insulation board 4. Protection of mullions 5. Mineral wool safing (compression fit)-proper orientation 6. Firestop sealant Image copyright Thermafiber Inc. Used by permission

21 MINERAL MUST BE COMPRESSED PROPERLY

22 PERIMETER FIRE BARRIER APPLICATIONS System No. CEJ-127 P Glass Spandrel Panel with Aluminum Framing Due to unique design of many curtain wall systems, EJs are typically issued

23 PERIMETER FIRE BARRIER APPLICATIONS System No. CW-D 1001 Pre-Cast Concrete Panels System No. CEJ-421 P Structural Fly-By Stud Framing

24 WHEN A TESTED FIRESTOP SYSTEM DOES NOT MATCH A FIELD CONDITION, ENGINEERING JUDGMENTS NEEDED Engineering Judgments are issued in accordance with the guidelines established by the International Firestop Council. Not to be used in lieu of available tested systems Must be issued by qualified technical personnel Based upon previously tested system(s) Based upon assumption that the recommended system (EJ) would pass if tested for the required rated period of time Issued only for a single job, location and application
