Firecheck® Type X

Lafarge Firecheck® Type X is gypsum board enhanced with glass fibers to offer greater strength and fire protection for use in interior walls and ceilings.

The board has a noncombustible gypsum core and paper facings on the front (ivory), back, and long edges. It is available in several edge treatments, and its ivory facing paper will accommodate a variety of decorative elements after proper surface preparation.

 

Firecheck Type X can be used in applications that require direct mechanical attachment to wood or metal framing, or as a component of fire-rated assemblies. It may also be used as a thermal barrier in roof assemblies when specified by the roofing manufacturer.

 

When used in a certified sound-rated assembly, Firecheck Type X will also contribute to required Sound Transmission Class (STC) values.

 

Note: Firecheck Type X is suitable for interior applications only and should not be used in environments where temperatures exceed 125 degrees Fahrenheit (52 degrees Celsius) for extended periods of time, or in areas of extreme humidity. To maintain performance integrity the board should be protected from exposure to adverse conditions during storage and construction. To ensure optimal Type X fire-resistance performance, users should follow the recommended installation procedures.

 

Applications:

Firecheck Type X is suitable for various indoor uses, including:

  • Interior walls and ceilings
  • Elevator enclosures
  • Stairwell enclosures
  • Area separation fire walls
  • Roofing substrates

Advantages:

Firecheck Type X offers several advantages over regular drywall:

Fire resistance: An enhanced level of fire resistance compared with regular drywall for both residential and commercial construction applications. Firecheck Type X is formulated to perform in accordance with ASTM C 1396, Sections 5 and C 36, Type X; and is UL labeled (Type LGFC6A).

Ease of installation: Fast installation, similar to that of regular drywall.

Identification: Firecheck Type X is clearly identified by the UL label on the back and "Type X" printed on the tapered edge of the face of the board.
