Gyproc® Firestop Board is gypsum based interior Wall & Ceiling product used in areas where High Fire Resistance Performance is required to restrict fire to pass from one side of wall to the other side.
Gyproc® Firestop Board’s gypsum core incorporates glass fibers & other fire resistive additives that are encased & firmly bonded to strong pink colored paper liners
Kenworks Ventures Company Limited Fire resistant Gypsum Boards in Kenya: Gypsum is approximately 21 percent by weight chemically combined water which greatly contributes to its effectiveness as a fire resistive barrier. When gypsum drywall is exposed to fire, the water is slowly released as steam, effectively retarding heat transmission.
- 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.
- Fire resistant gypsum board is referred to as “Type X” and must be third-party certified by an independent testing and listing agency to meet the fire performance requirements prescribed in the Standard Specification for Gypsum Board.
Types of Fire Resistant Gypsum Boards
Type X fire rated gypsum drywall that is 5/8 -inch (15.9mm) thick and installed on each side of nominal 2-inch x 4-inch (38x89mm) wood studs spaced 16-inch (400mm) o.c. or 3-5/8 inch (610 mm) steel studs spaced 24” o.c. has a minimum fire rating for the assembly of 1 hour, which is a typical requirement for many building codes.
Type C fire resistant gypsum board (sometimes referred to as Improved Type X) is similar in composition to Type X, except that it has more glass fiber reinforcement and other ingredients in the gypsum core that makes its fire resistive properties superior to Type X. It is available in 1/2-inch (12.7 mm) thicknesses.
Fire rated Type X Shaftliner is 1” (25.4 mm) thick and used in special Shaft wall and Area Separation Firewall assemblies.
Local and Government building codes require installation of fire rated boards in area such as furnace and utility room walls for residential applications. Fire rated drywall can also be installed in a basement or places where wood stove might be used. This enhanced gypsum board is typically found on attached garage walls and ceilings that are adjacent to the main living area of the home.
For commercial buildings, fire rated gypsum drywall is specified for most of the building walls and ceilings to meet building code requirements for fire partitions and assemblies. These fire rated partitions and assemblies provide life safety for the building occupants.
