Designed for external cladding, but is suitable for a wide range of applications.


Lightweight natural stone cladding with ventilated rainscreen system, combining a thin layer of natural stone with a fire-resistant composite board reinforcement through an exclusive bonding process.

Features and benefits:

  • Available in a wide range of natural and engineered stone types, and various different finishes.
  • Dimensionally stable and strong, ensuring the panels are suitable for high wind,
  • Good fire and mechanical performance.
  • Weighs approximately 65% less than traditional stone cladding, which helps with handling, installation and structural costs.
  • Suitable for use on buildings over 18 m in height.
  • Performs well in hot, cold, frosty and wet weather conditions.
  • The backing board is inorganic, negating any biological or pest infestation.
  • Helps to reduce acoustic and thermal transmission.
