- Type X is typically 5/8" thick. ...
- Type C can be ½" or 5/8" thick, and is often referred to as the "enhanced" version of Type X.
- Type C gypsum panels have an enhanced formulation compared to Type X formulations, i.e. ...
What is the fire rating of Type X drywall?
Norm Abram replies: The 5/8-inch, “fire-code” drywall (called Type X) increases a wall's fire rating to a minimum of 1 hour, from the 30-minute rating for standard ½-inch drywall. And it's not just thickness that makes the difference. Considering this, what fire rating is 5/8 drywall?
Is gypsum board and drywall the same thing?
They are all essentially the same thing, but different English-speaking countries use different names for what is almost the same item, although not always. Once again, gypsum boards are used in drywall, so the two are not precisely the same item. The reason they call it “drywall” is because the product is dry and ready for painting right away.
How many types of gypsum board are there?
column in fire is modeled for the four types of gypsum. The results of numerical the chemical composition of gypsum plaster boards. effective heat capacity, ISO standard fire, steel columns, dolomite, calcite. gypsum plaster boards can not be overestimated.
What is gypsum Type X?
The first fire code product is called type X drywall, which is made from gypsum that has noncombustible glass fibers. The material used for this product increases its fire rating to a minimum of an hour and is usually installed in projects such as area separation firewalls, shaft walls, and stairwell walls.
What is special about Type X gypsum?
Type X drywall has special core additives that allow it to be used in fire rated designs and usually comes in 5/8” thickness. Type X drywall products will have a UL/ULC Marking printed on the back of each board identifying it as a fire-resistance rated board.
Is all gypsum board type X?
This begins with an understanding of the different panel Types as defined by the industry. ASTM C1396, Standard Specification for Gypsum Board, categorizes gypsum board into only two groups: regular and special fire-resistant (Type X).
Is Type X gypsum fire rated?
Most Type X drywall has a one-hour fire rating. The fire rating for the 1/2-inch drywall used throughout the rest of the home is 30 minutes. As an added benefit, Type X drywall absorbs sound slightly better and is slightly stronger than conventional 3/8-inch or 1/2-inch drywall.
What are the different types of gypsum board?
The different types of gypsum board generally available in the market are clued wallboard, backing board, core board, fire-resistant gypsum board, water-resistant gypsum board, and gypsum form board.
What is Type C gypsum board used for?
CertainTeed Type C Fire Resistant drywall accepts most types of paints, textures and wall covering materials.
What kind of drywall do you use for a fireplace?
Fire-rated Drywall Type X It slows down the passage of fire rather than stops passage completely.
How many layers of gypsum are needed for a 2 hour rating?
two layersAs 2 hours of fire protection has become the standard for fire safety in America, it has become somewhat of a standard practice to include two layers of type X drywall within a building's perimeter in order to achieve this required level of fire safety.
Is all gypsum board fire rated?
All gypsum panels are fire resistant and produced in a range of thicknesses, core formulations and optional special performance enhancements.
Does ceiling drywall need to be fire rated?
A: First, fire-rated systems are only required if the garage shares a wall or a ceiling with the home. If you are doing repairs in the garage you should replace with like materials, but remember it is the wall system that is fire rated not the product itself.
What is a type C board?
During this time, USG invented an enhanced proprietary Type X board, commonly referred to as USG “Type C.” As with the Type X panels, the core of Type C contains glass fibers, only in a much higher percent by weight. In addition to the greater amount of glass fiber, the core of these panels also includes proprietary modifiers which provide greater fire-resistive qualities. It is for this reason that Type C board became synonymous with ceiling applications, while Type X became the standard for walls—and it’s been that way for more than 50 years.
What is fire resistance in gypsum?
Fire resistance, defined as the property of a building assembly to withstand fire or give protection from it, is first the ability of a building to maintain structural integrity and stability despite exposure to a flame. In applications, like wall and floor-ceiling assemblies, fire resistance serves as a barrier to flame spread, providing temporary refuge and time to escape.
Is a fire resistant board a type X?
As there is no formal industry definition for special fire-resistant board beyond “Type X,” there are no qualifications as to the performance differences between Type X and enhanced proprietary Type X boards. While enhanced proprietary Type X panels (including Type C) have been evaluated and are approved in more challenging constructions due to their superior fire-resistive qualities, these panels are still, by definition, a Type X, having met the ASTM C1396 minimum requirements as fire-resistant.
What is a regular gypsum board?
Regular Gypsum Board – a gypsum board with naturally occurring fire resistance from the gypsum in the core; or. Type X Gypsum Board – a gypsum board with special core additives to increase the natural fire resistance of regular gypsum board.
What is gypsum board?
Gypsum board is the technical product name used by manufacturers for a specific board with a gypsum core and a paper facing and may be further described as follows: 1 Regular Gypsum Board – a gypsum board with naturally occurring fire resistance from the gypsum in the core; or 2 Type X Gypsum Board – a gypsum board with special core additives to increase the natural fire resistance of regular gypsum board.
What is fire resistant gypsum board?
CertainTeed Type X fire resistant drywall is an interior gypsum board consisting of a solid set, fire resistive, Type X gypsum core enclosed in ivory-colored face paper and a strong liner back paper. CertainTeed Type X board features a specially formulated core providing fire resistance ratings when used in tested assemblies. Long edges are slightly tapered, allowing joints to be reinforced and concealed with joint tape and joint compound. CertainTeed Type X fire resistant drywall is available in a variety of lengths and widths.
What is CertainTeed type X?
CertainTeed Type X Fire Resistant Dry wall accepts most types of paints, textures and wall covering materials. The surface shall be primed and sealed with a full-bodied latex primer before applying a final decorative material. This will equalize the suction between the joint compounds and the paper surface. For best painting results, all surfaces, including joint compound, should be clean, dust-free and not glossy. If glossy paints are used, a thin skim coat of compound over the entire surface, Level 5 finish, is recommended to reduce highlighting or joint photographing. This method is also recommended for areas of critical sidelighting of natural or artificial light sources. A sealer application under wallpaper or other wall coverings is also recommended so the board surface will not be damaged if the covering is subsequently removed during redecorating. Joint treatment must be thoroughly dry before proceeding with primer-sealer application and final decoration. Applicable Standards and References ASTM C840 GA0216 GA-214 Consult the GA-600 Fire Resistance Design Manual or UL Fire Resistance Directory, Volume 1 for specific information regarding the construction of fire resistance rated assemblies.
Does CertainTeed gypsum affect air quality?
Although LEED rating systems do not currently address emissions for all building materials and their effects on indoor air quality, finished Certain Teed gypsum board products have no reportable VOCs and will not affect indoor air quality.
