07210/THCBuyLine 2999FIRE CONTAINMENT SYSTEMSWhy do you need “fire containment”?The first priority in building safety is containment of both fire and smoke to the area of origin. For mid- and high-rise buildings, fire and smoke must beprevented from spreading to the next floor. Since the floor assembly is typically a fire-rated system, a possible route for fire spread is through and upthe exterior curtain wall system, which is frequently overlooked. In order to protect this weak point, the exterior curtain wall system must (1) eliminatethe “flue opening” between the floor slab and spandrel panel, and (2) provide a fire containment barrier that causes the flames exiting the vision areaon one floor to be diverted and cooled so that they are less likely to ignite combustibles on the floor above.THERMAFIBER Life-Safety Fire Containment Systems protect perimeters by combining THERMAFIBER Safing Insulation, THERMAFIBER Curtain Wall or FIRESPANInsulation and THERMAFIBER SMOKE SEAL or FIRECODE Compound. Note: These products are designed to complement each other in an assembly andshouldn’t be combined with products having different fire-containment values.213In an unprotected curtain wall, or inone protected with low-melt glass fiberinsulation, there are three ways inwhich fire can spread from floor to floor.THERMAFIBER Life-Safety Fire ContainmentProducts compartmentalize fire,preventing it from spreading from thefloor of origin up to the floor above by:1. Through the space between the slab edgeand the curtain wall.2. Through the window head mullion andthen up through the cavity of the curtainwall.3. Out through the broken vision glass andback in through the curtain wall.1. Filling the slab-edge/curtain wall gap withThermafiber Safing Insulation2. Protecting the vertical mullions3. Providing a vertical barrier to fire usingThermafiber Curtain Wall or FireSpanInsulationSpread of fire(unprotected)THERMAFIBER Fire Containment(protected)Code RequirementsAll model building codes in the U.S.A. require that the gap at the slab edge/curtain wall interface be treated to maintain the same fire integrity as thefloor-ceiling. The THERMAFIBER Life-Safety Fire Containment Systems have been independently tested by Underwriters Laboratories and Omega PointLaboratories and accepted or recognized (ICBO ER-2331, California State Fire Marshal, OSHPD) as maintaining fire containment from floor to floor.How the THERMAFIBER System WorksTHERMAFIBER Curtain Wall and Safing Insulations have effectively stopped fire for manyyears.

At slab perimeters,THERMAFIBER SMOKE SEAL, FIRECODE Compound, or other approved smoke sealant is used toseal the THERMAFIBER Safing Insulation to both the foil facing of THERMAFIBER Curtain Wallor FIRESPAN Insulation and the floor slab. This seal completely bridges the top of theopening between the slab and the curtain wall, effectively eliminating the passage of fireand smoke through this area.2400 F1315.6 CFire ContainmentLIFE-SAFETY

(See specific testdesign for details.)1. THERMAFIBER Curtain Wall (CW) or FIRESPAN Insulation is mechanically attached to mullions and transoms usingimpaling pins, screws or other positive mechanical attachment.2. Exposed aluminum mullions must be protected with THERMAFIBER Curtain Wall (CW) or FIRESPAN Insulation mullioncovers. (See specific test design for details.)3. THERMAFIBER Safing insulation is compression fit (minimum 1/2” wider than opening) (see specific test designfor details) into safe-off area (2”-8”) and supported with safing “Z” clips (optional in some designs).4. A light steel angle or channel is placed horizontally at the safing line, attached to vertical mullions—eitherwithin the insulation at a horizontal splice, or behind the insulation and attached to vertical mullions. This detailprevents bowing of curtain wall insulation due to the compression fit of the safing insulation.5. To further resist passage of smoke, systems that do not include FIRECODE Compound or other approved smokesealant should utilize foil-faced THERMAFIBER Safing Insulation (flush with the top of the slab) and be perimetercaulked with THERMAFIBER SMOKE SEAL Compound; or utilize a 1/2” fill of THERMAFIBER SMOKE SEAL Compound overthe Foil-Faced THERMAFIBER Safing Insulation (recessed 1/2” from the top of the slab).2glass, aluminumor stoneTHERMAFIBER CW 2or FIRESPAN insulationpinned to mullion covers1Smoke Sealant 554 stiff-back angle3Foil-faced or 3unfaced THERMAFIBERsafing insulationsupported by Z-clipssteel angleinsulation hangers4THERMAFIBER CW or 1FIRESPAN insulationpinned to angle clipsaluminium curtainwall systemSteel Stud-Framed Curtain Wall Systems—Design CriteriaSteel Stud-FramedCurtain Wall Systems—Design CriteriaThe following checklist contains important details that must be included in a THERMAFIBER Fire ContainmentSystem used in an steel stud-framed curtain wall system.

Selector—Curtain Wall Fire ContainmentGlass SpandrelCurtain Wall FireContainmentFIRE CONTAINMENT SYSTEMSTraditional fire testing procedures are designed to evaluate a specific element (wall, beam or floor-ceiling)independently. However, in curtain wall fires, the simultaneous attack of fire and smoke on several constructionelements dictates the need for a method to evaluate the independent elements of a fire-containment system asa whole. Thermafiber Inc. is actively participating on a technical committee with the American Society of TestingMaterials (ASTM) to develop a standard test method for determining the fire-endurance of different curtain wallfire-containment assemblies. Underwriters Laboratories (UL) and Omega Point Laboratories (OPL), testing withthe Intermediate-Scale, Multi-Story Test Apparatus, have tested and listed Thermafiber in over 50 curtain wallsystems in their Fire Resistance Directory under a new classification titled “Perimeter Fire ContainmentSystems.” These UL and OPL-Classified systems, along with tests witnessed by UL and other independentparties, are noted in the selector below. Note: Low-melt-point insulations cannot be substituted for THERMAFIBERInsulations in any tested assembly.

Tests are identified as WJE 3-3-72 and USG 11-30-71.Performance ofUninsulated PanelsTHERMAFIBER fire-tested an unprotected granite panel curtain wall system in February 1989 to determinewhether stone panels need fire protection to maintain their integrity in curtain wall assemblies:– THERMAFIBER Safing Insulation alone (no CW insulation) was used to fill the void between the slab edge and thegranite panel.– At seven minutes into the ASTM E119 (ANSI/UL 263) time-temperature controlled test, cracks formed in the3 cm thick granite panel, and went completely through the granite.– Conclusion: Without the additional fire protection of curtain wall insulation, the granite panel system may fail.Performance ofLow-Melt-PointInsulationsA glass spandrel panel system was also fire tested. It was protected with glass fiber curtain wall insulationand THERMAFIBER Safing Insulation. The purpose of the test was to determine whether glass fiber insulations canbe used for fire-containment in conjunction with THERMAFIBER Safing Insulation.– At ten minutes into the ASTM E119 (ANSI/UL 263) time-temperature controlled test, the glass fiber insulationbegan to melt.– At 21 minutes, 45 seconds, the glass spandrel shattered.– When the glass shattered, the THERMAFIBER Safing Insulation fell out intact.– Conclusion: Glass fiber insulations readily melt in fire, providing insufficient fire containment.Smoke ControlAfter successfully developing systems to provide fire containment in curtain wall and penetration applications,Thermafiber addressed a second life-safety concern, smoke control. The company developed and tested smokecontrol systems for the following reasons:– Smoke Inhalation causes 75% of all fire deaths.– 65% of all fire deaths occur away from the fire room.– There is no industry-accepted test method to evaluate the ability of a material or assembly to contain smoke, inperimeter fire containment systems.– Contact a Thermafiber representative for more information on smoke control.Thermafiber Inc.7www.thermafiber.comSafing1StaticDesign #CEG 4-2-81
LIFE-SAFETYSoundAttenuationFire BlanketsFIRE CONTAINMENT SYSTEMS07210/THCBuyLine 2999THERMAFIBER Sound Attenuation Fire Blankets (SAFB) are nominal 2.5-lb./cu. ft. (4 lb./cu. ft. for 1”) density blanketsspecifically intended to be used for sound attenuation in walls and ceilings. They are highly effective in reducingsound transmission. They are provided in standard widths of 15”, 16”, 17”, 24” and 25” by 48” length for installationbetween studs or joists. They are available in thicknesses of 1” to 6” (in 1/2” increments) to provide a variety oflevels of sound attenuation.They are particularly useful in partitions requiring fire ratings and as overlayment foracoustical tile or panel ceilings to improve acoustics. Surface burning characteristics are flame spread 0, smokedeveloped 0.Sound AttenuationFire BlanketAssembliesDepending on the particular assembly and application, partition STC ratings have been improved up to eleven pointsby installing THERMAFIBER SAFB in the stud cavity. The insulation also has been shown to improve MTC ratings forlow-frequency sound attenuation, isolating sounds from machinery, mechanical equipment and music.THERMAFIBER SAFBs are superior to glass fiber in sound attenuation. In fact, low-density ( 1 lb./cu.ft.) glass fiberinsulation requires greater thickness than standard THERMAFIBER SAFB to provide the same attenuation.Creased THERMAFIBERSAFB AssembliesThese engineered assemblies offer the most economical drywall and veneer plaster sound systems in the50 to 55 STC range. They are also fire-rated, making them ideal for party and corridor walls in hotels, motels,offices and multi-family dwellings. The Creased THERMAFIBER SAFB system is a patented insulation blanketassembly that is 1” wider than regular blankets. After the blanket is installed in the partition cavity, a 1” verticalslit is field-cut partially through the center of the blanket, allowing it to be creased. Compressing the extra widthinto the stud cavity buckles the center, exerting pressure against both studs and drywall. This pressure dampenssound vibrations and boosts the partition’s STC rating. For example, a single-layer drywall partition with CreasedTHERMAFIBER SAFB has the same STC rating as an unbalanced drywall partition with standard SAFB.For further information about THERMAFIBER SAFB and Creased SAFB, request TF885, Thermafiber SoundAttenuation Fire Blankets (SAFB) available from Thermafiber Inc.61 STC*2-hr. partition, resilient channel—3” THERMAFIBER SAFB in stud cavity—1/2” gypsum wallboard Type C core—3-5/8” 20 ga studs 24” o.c.—RC-1 channel or equivalent one side, spaced 24” o.c. screw-att to studs—3 layersgypsum panels screw-att to studs, double layer screw-att to chan—joints stag and fin—perimeter caulked—ULDes U419 or U455—RAL-TL-87-153A-2856 STC2-hr. partition, double-layer drywall—2” THERMAFIBER SAFB in stud cavity—2 layers 3/4” SHEETROCK Brand gypsumpanels, ULTRACODE core, ea side—2-1/2” 25 ga steel studs 24” o.c.—panels screw att with joints stag and fin—UL Des U419, U490-ULCW441 or SA-91090759 STC/69 IIC*2-hr. ceiling—double-layer drywall—3” THERMAFIBER SAFB—floor of carpet/pad, 1-1/2” flooring 1/2” plywood—2x 10 wd joists 16” o.c.—ceiling of 2 layers 5/8” gypsum wallboard Type C core, over RC-1 channels or equivalent16” o.c.—UL Des L541—RAL-TL90-40/RAL-IN-90-550 STC*1-hr. partition—single-layer drywall, resilient channel—3” THERMAFIBER SAFB in stud cavity—5/8” gypsum wallboard Type C core—2 x 4 16” or 24” o.c.—RC-1 channel or equivalent one side, spaced 24” o.c.—panels apphoriz & att to channels—end joints back-blocked with RC-1 channel with 1” TYPE S screws—opp side direct attwith 1-1/4” TYPE W screws—joints fin—perimeter caulked—UL Des U311 and ULC U311—BBN-760903*STC values are based on Sheetrock Brand gypsum panels, Firecode C.Thermafiber Inc.8www.thermafiber.com
