What is Powerscape Fiberock made off?

95% of the raw material in Fiberock comes from recycled external waste streams

  • 85% is post industrial gypsum, a waste product obtained from an electricity generator. No open cast or underground mining of gypsum is needed for the manufacture of Fiberock linings
  • 10% is recycled cellulose, meaning no trees are harvested for the manufacture of Fiberock linings.

What makes USG Powerscape Fiberock so special?

The patented Fiberock technology

In the manufacture of Fiberock interior linings a highly refined cellulosic fibre is heated, under pressure, in a ground gypsum rock slurry. During the process volatile materials are removed. The process mineralizes the fibre, with the gypsum rock nucleating into natural apertures in the fibre walls. As a result, exceptional strength and stiffness are achieved. The lining surface is formed by 'floatation'. This process directly creates a smooth mineral rich surface, and avoids fibre fluff typically experienced with many other products that need to be sanded smooth during production. Fiberock interior linings are finished with a factory baked on clear sealer, which creates an even suction for subsequent jointing, painting and other finishing systems.

These three scanning electron microscope images show, with increasing magnification (from left to right), the close bonding of cellulose fibre strands to the gypsum rock crystals, including the formation of gypsum crystals within the natural apertures in the fibres themselves. It is this bonding, achieved through this new patented manufacturing process, that underpins the exceptional impact resistance and durability of Fiberock.
