External wall insulation system combining the elegance and outstanding impact resistance of a natural stone finish with thermal insulation. The natural stone panels are strengthened with fabric reinforcement and can be bonded to the substrate without the requirement for mechanical fixings at ground level. The maximum thickness of the stone is 12 mm, enabling a slim wall construction to be achieved.

Features/ Benefits:

  • External wall insulation with fabric reinforced stone panels.
  • Slim wall construction.
  • Available in a variety of standard finishes and individual types of natural stone, ceramic tiles and brick slips.
  • Provides outstanding impact and weather resistance.
