2 Can be used in townhouses up to four stories ( m (44 ))tall and with all common floor-ceiling heights. It must either be continuousfrom the foundation to the underside of the protected roof sheathing, orcontinue through the roof to form a fire wall is designed to allow for collapse of the construction onthe fire -exposed side without collapse of the entire wall. To do this,aluminum breakaway clips attach the separation wall to the adjacentframing. When one side is exposed to fire , the clips are designed tosoften and break away, allowing the structure on the fire side to collapse,while the clips on the exposed fire side of the separation wall continueto support the wall.

4 These systems install quickly and easily. Because they weigh at least50% less than masonry walls , installation proceedsrapidly. In addition, use of these assemblies gains valuable floor space for the building interior, since thickness is 89 mm (3-1/2 ) compared to 200 to 300 mm(8 to 12 ) for a masonry wall without interior Gypsum fire Wall SystemsComponentsCGC fire Wall Systems have been comprehensively tested for fireresistance ratings only when all of the system components are usedtogether. Substitutions of any of the components are not recommendedand are not supported by CGC.

7 Performance Tests Extensive testing and continuous improvements ensure that CGC fire Wall Systems will provide the vertical fire resistance and sound performance that projects Methods CGC fire Wall Systems have been tested to ensure long-term CGC products and systems undergo exhaustive testing to ensure that they meet exacting standards. CGC s products are Classified as to fire resistance and fire -hazard properties. As part of this protocol, UnderwritersLaboratories of Canada, (ULC) and Underwriters Laboratories Inc.(UL) periodically audit production of these materials toensure compliance with necessary properties.

8 ULC and UL are independent, not-for-profit product safety testing andcertification organizations that have tested products for public safety for over a and systems are tested in accordance with ASTM standards. ASTM 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 Transmission Class (STC) rates the effectiveness of walls and other components at blocking airborne Protection ResultsFire walls must ensure that fire does not spread from one townhouse to the next.

9 Building codes mandate that fire wallsare tested according to specifictest standards, such as CAN/ULC S101, or ASTM E119, Standard Test Method for FireTests of Building Construction and Materials, or its resistance testing ensures that this critical performance component will not be compromised when the systemis properly installed. fire testing results in the following: ULC/UL Classification of all Gypsum panel components for fire resistance ULC/UL listing of system fire resistanceSound Control Sound control test data demonstrate the effectiveness of CGC fire Wall Systems in attenuating sound.

10 This means thatoccupants of adjacent buildings will have more privacy. STC ratings up to 60 are The best way to minimize damage from moisture and mold is to minimize or eliminate exposure to water before, duringand after construction. In all cases where moisture intrusion occurs, eliminate all sources of moisture Liner Panels have a noncombustible, moisture-resistant core encased in a water- and mold-resistant, 100% recycled blue face and black paper. When used in conjunction with good construction practices, this productwill minimize, but not eliminate, the risk of moisture LEED (Leadership in Energy and Environmental Design) program is a guideline for building solutions establishedby the Green Building Council (USGBC).
