Gold Bond Fire-Shield Gypsum Board
Gold Bond® BRAND Fire-Shield® Gypsum Board was developed to work in combination with other products in an assembly to retard heat transfer through the assembly. Fire Shield gypsum boards are made with cores formulated to offer greater fire resistance than regular gypsum board. Generically, these fire resistant boards that are used to delay heat transfer to structural members are designated as "Type X" products.
The gypsum core of Fire-Shield Gypsum Board works as a natural "sprinkler system." Gypsum naturally contains about 21 percent water. When the board is heated, the water in the core begins to evaporate and is released as steam, retarding heat transfer. Fire-Shield gypsum board remains noncombustible. However, as shrinkage occurs because of the loss of water volume, cracks occur which permit passage of fire and heat. To lessen this process, Fire-Shield gypsum board is formulated by adding noncombustible fibers to the gypsum to help maintain the integrity of the core as water volume is lost while providing greater resistance to heat transfer.
Applications
- 1/2" For single-layer application in residential construction and single or multi-layer construction for fire tested assemblies (Fire-Shield C). Also used as a roofing substrate (Fire-Shield C).
- 5/8". (Fire-Shield or Fire-Shield C only) For the single or multi-layer drywall construction. The greater thickness provides increased resistance to fire and reduced sound transmission.
Features & Benefits
- Lightweight, cost-efficient material that readily accepts a wide range of decorative finishes.
- Gypsum Board is easily-cut for quick installation, permitting painting or other decoration and the installation of metal or wood trim almost immediately.
- The gypsum core will not support combustion or transmit temperatures greatly in excess of 212°F (100°C) until completely calcined, a slow process.
- Expansion and contraction under normal atmospheric changes is negligible.
GREENGUARD Certified
Gold Bond® BRAND Fire-Shield Gypsum Board with Sporgard is GREENGUARD Children & Schools Certified® for indoor air quality.
The GREENGUARD Children & Schools Certified® Mark is a registered certification mark used under license through the GREENGUARD Environmental Institute.
The GREENGUARD Certification ProgramSM is an industry independent, third-party program that has been certifying products for low non-toxic emissions since 2001. To achieve GREENGUARD Indoor Air Quality Certified status, National Gypsum's products passed rigorous sample testing and review of the manufacturing processes to meet strict standards set by the GREENGUARD Environmental Institute (GEI) — a globally recognized leader in indoor air quality — to determine their impact on indoor air pollution. To achieve GREENGUARD Children & Schools Certification, Fire-Shield Gypsum Board met even more stringent emissions limits that take into account the added sensitivity of children and adults with compromised immune systems.
