Gyprock Fyrchek has been developed to take the heat. Fyrchek’s specially processed glass fibre-reinforced gypsum core makes it ideal for use in fire rated wall and ceiling systems and where improved acoustic performance is required.

Product Overview

Fyrchek’s glass fibre-reinforced core enables it to maintain structural integrity when subjected to direct flame making it an ideal board for use as part of a fire rated wall or ceiling system.

This plasterboard is also an acoustic grade board and can be used in systems where acoustic separation is specified.

Gyprock Fyrchek can be easily identified by its pink coloured face paper.

Typical Applications

Fyrchek is predominantly specified for commercial installations in areas where there is a higher level of fire resistance and/or acoustic performance required.

Typical applications include:

  • Fire separation and smoke walls
  • Intertenancy walls and party walls
  • Multi-residential unit ceilings
  • Lift wells
  • Plant rooms
  • Any non-wet area wall or ceiling where a fire or acoustic rated system is specified


Protect plasterboard and cornice from weather and moisture. Avoid products sagging by storing horizontally, supported on a level platform or full-width support members spaced at max. 600mm centres.
