A local volcanic eruption is a substantial risk to the Auckland region. Research into the impact of multiple volcanic hazards on the roofs of buildings showed that they generally deal well with volcanic ash and flying rocks landing on them.

Costs can be lowered and accidents avoided if time is spent thinking about safety at a project’s design stage. This can range from the number of employees and the materials used, through to putting in permanent safety systems.

To simplify the consenting process for structural insulated panels (SIPs), we need to know how they perform locally. A BRANZ research project is helping by examining SIP durability, earthquake and fire performance.
