Meaning that fire resistant board fits zones where high level of fire protection is needed. 4 CGC Gypsum Fire Wall Systems Overview Effective fire resistance and sound attenuation are important considerations in townhouse design. Glass fibers are added to the board to help it slow down the fire. This crystallized water is very stable in normal condition and does not disperse, but once it comes in contact with the heat of fire it will cause thermal decomposition and start to evaporate. Nowadays, fire safety requirements are guided by The Building Code of Australia (BCA) which outlines the requirements for fire performance of gypsum walls and ceilings to help ensure the safety of occupants in the event of a fire . Durable Gypsum boards are used to construct strong and high quality walls and ceilings. Capable of fire resistance rating from 1 to 4 hours. To review a collection of these system assemblies that meet a wide range of design requirements, refer to GA-600 Fire Resistance and Sound Control Design Manual. Type X gypsum board is specially treated with additives to further improve its fire-resistive qualities. The impact of gypsum dehydration in CFD simulations is investigated using 3 models. Gypsum board, also known as drywall, consists of a layer of gypsum sandwiched between two sheets of paper. Most importantly, exterior gypsum boards are used for wall cladding. Fire rated gypsum drywall is more fire resistant because it contains glass fiber reinforcement and other additives within its specially formulated gypsum core to help it hold up longer to a fire exposure. The special fire-resistant properties of gypsum plaster have since been used for centuries for fire protection. SoundBreak XP Retrofit Board is one layer of 5/16" high-density gypsum board with viscoelastic polymer on the back side covered by an additional layer of heavy mold .

By any name--drywall, wallboard, or plasterboard--gypsum products may not be as innocent as we once thought. Also, because it is denser than normal gypsum and paper drywall, it takes longer for the fire to degrade it. The fire resistance class of the material is determined by the fire resistance limit. Staples are used because they are economical and can be quickly applied with staple guns; however, the use of staples should be limited to the base-layer in multi-layer systems or to gypsum . Fiber Cement Board. Unless the system is being used as a sound or smoke barrier, or as part of a seismic- or wind-resisting system, you pretty much can cut the hole, run the penetrating element, seal around the hole with some joint treatment, and walk away. Fire resistance of gypsum plasterboards is owed to the gypsum dehydration process. 1. Gypsum Board Installation Drywall is normally installed by fastening it, using drywall screws, directly to wood or metal studs and joists located in the walls or ceilings of a structure. 24 results Filter By Special Property.
