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

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

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. USG Fire Stop Systems

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.

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 0 5 5 0 0 Smoke Developed 0 0 0 0 0 (a) pproved by NYC (ME -9-M) and L City (RR#5).

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.

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-).

Ensure that firestopping sealant is in contact with all surfaces and that the entire opening is filled with safing (if required for system applications) and firestopping sealant. The specific system design will specify the necessary amount of forming material and the permitted joint or annular space. B. Spray pplication Mixing FIRECODE Compound powder Use drinkable water and clean mixing equipment. Mix 8.5 to 9.0 pints water per 5 lbs. of FIRECODE Brand Compound. Mix powder thoroughly into water until powder is completely wet. Mix until smooth. Let initial mix soak approximately one minute. Remix approximately one minute, adding water necessary to achieve desired working consistency. FIRECODE Compound premixed ctivated compound should be thinned with water. Mix using drinkable water and clean mixing equipment. Use 0.5 pints water per gallon of FIRECODE Compound premixed. Product will be stable for approximately one hour of spraying time. Do not retemper. Hardening cannot be prevented or delayed by dilution with water. Do not intermix previously mixed or sprayed material into freshly mixed material. Intermixing will accelerate the chemical setting of FIRECODE Brand Compound, causing short working time, resulting in substandard bond and unsatisfactory surface matrix harness. Do not intermix with other joint compounds. Store bags in a dry place. If moisture damage occurs, do not use any set lumps of material. Spray Equipment (FIRECODE Compound) Roto/stator (Moyno pump) or peristaltic pump may be used. Use minimum length material hose with minimal line splices to reduce clogging. Product will be tank stable for one hr. of spraying time. Pump and hose must be primed with water prior to spray application. Clean equipment thoroughly between and after applications. Use plaster system scouring sponges to prevent buildup inside hoses. Rotor/stator (Moyno pump) Use Robbins-Myers L pump or similar equipment as minimum pump size, with pole gun with / to /8 round orifice. Use / to i.d. material hose, /8 atomizing hose and / air line from the compressor to the pump. Peristaltic pump Use pump with minimum i.d. internal pumping and material hose. Use pole gun with / to /8 round orifice. Use minimum i.d. material hose, /8 atomizing hose and / air line from the compressor to the pump. USG Fire Stop Systems

pplication Guide Specifications pplication (FIRECODE Compound) Spray application rate of FIRECODE Brand Compound is approximately gal. (6 cu. in.) per min. Typical spray patterns are between - using 0-0 psi air pressure. The spray gun should be held as close to the penetration being filled as possible to reduce overspray and waste, typically -. void excessive air pressure. Material may be applied up to a finished thickness in a single coat; however, best results are achieved by building up to the finished thickness in / coats. FIRECODE Brand Compound will stiffen approximately 5 min. after spray application, allowing for quick recoating or hand tooling. Set time of the sprayed material will be approximately 0% less than for the unpumped material. Do not recycle material that has been pumped (such as wipedown or initial flushes of material). The pumping process accelerates set. If recycled material is mixed with fresh product, the material will set faster than normal and will set up in the equipment. The practice of recycling sprayed material will result in bond failure and unsatisfactory surface matrix hardness. Do not let material sit in the hose for longer than 0 minutes If longer breaks are needed, flush out the hose with water and then restart. Spray Equipment (FIRECODE Brand crylic Firestop Spray Sealant-Type S) Working pressure shall be minimum 000 psi with a delivery rate of minimum.0 gpm. The spray tip orifice shall be 0.09. larger tip may be used if the pump can support it. The fluid line is minimum /8 i.d. for a length of up to 50. Equipment should be flushed with water at the end of the day. irless spray equipment operates at extremely high pressures. Protective clothing, gloves and eye protection are required. pplication (FIRECODE Brand crylic Firestop Spray Sealant-Type S) pply FIRECODE crylic Firestop Spray Sealant (Type S) to the required depth using spray equipment, brush or trowel. The application should extend / onto both the deck and wall surfaces to ensure proper installation of the sealant over the entire joint area. Masking tape can be used to create a neat appearance.
