Building System

Our CodeMark is the first of its kind for a building envelope system and the most comprehensive on the market


With 20 years of building envelope development and 15 years of Magnesium Sulphate (MgSO4) sheathing recipe refinement, we can deliver you a better building product that exceeds NZ’s building code and requirements.

  • By exceeding NZ building code requirements, we minimise the need for additional engineering with every panel providing significant bracing and impact resistance.

  • The entire surface is structural and load-bearing – with roof panels strength tested to hold a span of up to 7.2 meters thanks to our unique box spline and the use of pressed steel internal components.

  • The advanced science behind our panels allows for wind loads to ‘extra high’ – supporting specific designs for cyclone conditions.

  • Our product’s seismic design capabilities have been developed in New Zealand through extensive research and development using regional engineers and third-party test laboratories to address ductility, durability, and strength for New Zealand conditions.
