1 Fire-rated sealants for floor and wall through-penetrations Fire Stop Systems

2 While electrical, plumbing and mechanical systems are a necessity in building construction, it is often necessary to pass these systems through hourly fire-resistive floor or wall assemblies. Typically, openings are cut or drilled through the floor or wall, and then the penetrating items are installed. However, this leaves an opening, or annular space, through which fire can spread. Firestop materials are installed within the openings and around the penetrants to prevent the passage of flames and hot gases through an otherwise fire-resistive assembly. Fire Spread Prevention

4 Overview The intersection where two fire-rated assemblies meet (for example, a wall assembly and a floor/ceiling assembly) also creates a joint through which fire can spread. To prevent this, fire-rated construction joint assemblies are installed at these intersections. USG Fire Stop Systems address this problem of openings in the barrier. They consist of mortar-, caulk- and intumescent-type materials that provide reliable firestops. Mortar-type Materials These materials are applied wet over the forming materials (where applicable). They then set or harden to form a tough, durable seal. Typically used in walls, floors and curtain wall slab-edge conditions where strength and economy are required. Caulk Materials These materials are applied from a caulking tube or pail, or are spray-applied. They dry to form a flexible seal. These products are typically used in dynamic joints in head-of-wall designs, as well as certain floor and wall penetrations where movement is anticipated and flexibility is a requirement. Intumescent-type Materials Greatly expanding when exposed to high temperatures, these materials are only necessary when the integrity of the penetrants is compromised by high temperature, such as in plastic pipes or some insulated pipes.

5 pplications USG Fire Stop Systems consist of special sealants that are trowelled, poured, sprayed, wrapped or caulked around a penetrant (for example, pipe, conduit, duct or cable bundles) through a wall. The sealant prevents the passage of fire through a fire-resistive partition or floor-ceiling assembly.

6 Components USG Fire Stop Systems have been comprehensively tested for fire resistance ratings only when all of the system components are used together. Substitutions of any of the components are not recommended and are not supported by USG. Refer to the appropriate product material safety data sheet for complete health and safety information. Mortar-Type Materials FIRECODE Brand Compound Provides a strong, durable firestop with exceptional economy pplied in wet form and allowed to set or harden Mix only what s needed for the application at hand (mix powder-type with water and premixed-type with activator powder) Withstands the thermal and mechanical shock of high pressure hose stream testing Fresh compound bonds to cured compound, simplifying repairs due to construction damage or changes to penetrating items Mixes quickly and easily with water at jobsite Consistency of the compound may be changed to suit application Once mixed, sets in hours and bonds to concrete, metals, wood and cable jacketing without the use of primers Dries to a red color easily seen and identified by fire marshals May be sanded smooth and painted with either latex or oil-based paints Refer to submittal sheet J5 for more information Caulk-type Materials FIRECODE Brand crylic Firestop Sealant-Type and FIRECODE Brand crylic Firestop Spray Sealant-Type S Simple to install using either a caulking gun or airless spray equipment (FIRECODE Brand crylic Firestop Spray Sealant) crylic, elastomeric material is capable of ± 5% movement in a fire-rated joint vailable in rust red, a color easily seen and identified by fire marshals Lowest installed cost for head-of-wall applications Can be painted once fully cured Sprayable grade offers savings in head-of-wall applications with long joint runs Refer to submittal sheets J65 and J66 for more information SHEETROCK Brand coustical Sealant Reduces sound transmission in partition systems to achieve specified STC values Seals spaces at perimeters of partitions or around cutouts Easily applied on vertical and horizontal surfaces Remains flexible when dry Off-white, can be painted once fully dry Maximizes sound attenuation with complete perimeter seal of both faces crylic water-based caulking material Refer to submittal sheet J678 for more information 6 USG Fire Stop Systems

8 Performance Testing When you specify USG Fire Stop Systems, you are selecting one of the most important elements in the building. For that reason, you should choose the system that ensures superior safety and performance. Performance Tests USG Fire Stop Systems result from a program of extensive testing and continuous improvements, backed by over 00 years of experience in the building materials industry. Testing Methods ll USG products and systems undergo exhaustive testing to ensure that they meet exacting standards. USG s products are Classified as to fire resistance and fire-hazard properties. s part of this protocol, Underwriters Laboratories (UL) periodically audits production of these materials to ensure compliance with necessary properties. UL is an independent, not-for-profit organization that has tested products for public safety for over a century. Products are manufactured and tested in accordance with STM standards. STM International is one of the largest voluntary standards development organizations in the world, and is a trusted source for technical standards for materials, products, systems, and services. The USG Fire Stop Systems tests include: STM E8 (NSI/UL 7): Surface Burning Characteristics STM E8 (NSI/UL 79) and ULC-S5: Standard Test Method for Fire Tests of Through-Penetration Fire Stops STM E966 (NSI/UL 079): Standard Test Method for Fire-Resistive Joint Systems STM E90: Standard Test Method for Laboratory Measurement of irborne Sound Transmission Loss of Building Partitions and Elements Testing Results Fire Resistance FIRECODE Brand FIRECODE Brand FIRECODE Brand FIRECODE Brand SHEETROCK Brand Compound a crylic Firestop crylic Firestop Intumescent coustical Sealant-Type b Spray Sealant- crylic Firestop Sealant-Type S Type S b Sealant-Type I b STM E8 STM E8 STM E966 STM E90 STM E8 Flame Spread Smoke Developed (a) pproved by NYC (ME -9-M) and L City (RR#5).

9 Fire Containment Curtain Walls Code Requirements U.S. model building codes require that the gap at the slab edge/curtain wall interface be treated to maintain the same fire integrity as the floor/ceiling. The life-safety fire containment systems have been tested (UL Systems CW-S-00, CW-S-00 and CW-S-00) and accepted or recognized (ICBO ER-, California State Fire Marshal, OSHPD) as preventing the passage of flame at the interface for the classification period.

29 Construction Joint Fire Tests Construction joints are used at locations where two fire-rated assemblies intersect. These locations include: Wall to floor/ceiling or roof/ceiling (head-of-wall application) Wall to wall (building expansion joint application) Floor to floor (building expansion joint application) Floor to wall Construction joints are evaluated in accordance with the Standard STM E966 (NSI/UL 079) for their ability to resist flame and temperature transmission as well as the hose stream. special variation to construction joints is the intersection of a fire-rated floor and an exterior curtain wall. ccording to UL, curtain wall slab edge conditions are not suitable for evaluation under UL 079 because curtain walls are primarily non-fire-rated assemblies. Underwriters Laboratories has evaluated several United States Gypsum Company head-of-wall assemblies under the Standard UL 079. These assemblies are recognized by ICBO (ER-). These assemblies are separated into static (no floor or roof movement) and dynamic (to accommodate deflection). llowable movement is noted in the separate designs. 9 USG Fire Stop Systems
