Fireboard: What it is and why you should use it

Posted on by Maltings Timber Team


Fireboard is becoming an increasingly popular wall lining within industrial construction thanks to its highly fire retardant features and host of other benefits. Whilst drywall has a proven track record of providing a sturdy and reliable wall lining, this article will outline why fireboard may be the better choice for your construction.

What is fireboard?

Fireboard is a form of fire retardant drywall made from a hybrid of fibreglass and drywall. Consisting of a fiberglass layer that reinforces the gypsum layer, this wall lining doesn’t disintegrate as quickly as regular drywall and prevents fires from spreading from room to room as rapidly.

The uses of fireboard

Fireboard’s main use is primarily as a drywall replacement in office buildings. It can also be installed on steel beams and structural supports as an encasement. This is because fireboard has a smooth white appearance and plaster and paint can be used as a finishing layer. Within an office environment, this produces a much more pleasing appearance than exposed steel.

At Maltings Timber the fireboard we supply is Maxwood, which can be used for the following purposes:

  • Fire door construction
  • Window surrounds
  • Fireplace surrounds
  • Under roofs and in walls

The benefits of fireboard over standard drywall

  • Increased fire resistance – fireboard offers resistance to fires and smoke for up to twice as long as drywall.
  • Higher moisture resistance – drywall is very easily damaged if exposed to water and can develop mold that leads to warping if in damp conditions. Firewall is moisture resistant and can be used in high-moisture rooms such as bathrooms.
  • Fireboard is much more soundproof than layers of regular drywall.
  • Increased insulation.


Fireboard installation requires a professional installation technician who is used to working with the material. Specialist materials for installation are supplied by the manufacturer, including spoon-tipped gold screws that are used to fasten the boards together. A special joint compound that is needed to fill gaps in the board joins is also required. It is also recommended to finish the boards with a heat resistant spray.
