About Building Boards

Building boards for a wide range of internal building applications including Fermacell, Hardiebacker and Moistsure building boards:


Fermacell is a range of gypsum building boards for use on walls, ceilings and floors. Fermacell has been developed to the highest standards of German engineering.  

Fermacell boards have a simple, uniform structure:

  • recycled gypsum
  • cellulose fibres from post-consumer waste paper and water
  • no added chemicals

Fermacell building boards are fibre-reinforced throughout which makes them extremely resilient and provides excellent sound insulating properties. Fermacell is a universally applicable material - as straightforward building boards, for fire protection purposes and in rooms where resistance to moisture is required. Fermacell outperforms traditional dry-lining where other systems need multiple layers and separated studs to achieve similar impact, acoustic and fire ratings.


Hardiebacker boards are 12mm thick cement building boards for tile and stone, designed to be used as an alternative to plasterboard for tiling on walls.

Hardiebacker is a water-resistant, cement backer-board for tile that fastens directly to the wooden frame of a wall. A good tile job begins with using the right materials, and when tiling onto a wall in a wet area, there are a few important things to consider.

  1. HardieBacker cement building boards are impervious to water damage and will not rot, crack, or swell in the wettest conditions.
  2. It contains MouldBlock Technology™, an anti-mould additive that prevents unseen mould growth behind the walls. It contains no paper facing, a food source for mould or gypsum, which can disintegrate with continuous water exposure.
  3. Unlike plasterboard, HardieBacker board has a unique cement formulation providing a strong bond to all ceramic or natural stone tiles for applied weights of up to 100kg/m2.
  4. It is non-combustible and carries an A1 fire rating. HardieBacker 12mm can also be used on the floor when additional height is needed, behind a boiler, or even behind a multi-fuel or log burning stove.


MoistSure building boards are moisture & water resistant – will not swell, rot or degrade. They're also mould and mildew resistant. MoistSure building boards are environmentally friendly thanks to a low carbon manufacture and are available in easy to handle sizes that are straightforward to attach. MoistSure boards are A1 fire-rated (non-combustible).

"Many other tile backer boards are very difficult to score and snap and require up to 6 scores on each straight edge with a specialist cutting tool before the board can be snapped to size. MoistSure building boards are easily scored and snapped with a standard cutting blade, resulting in easier installation and fitting savings of time and money." - MoistSure.
