Steel-faced SIPs emerged in Australia during the 1980s, initially for cold storage applications. Bondor pioneered local manufacturing with SolarSpan® in the 1990s, followed by Metecno's PIR technology introduction. The 2009 Victorian bushfires drove development of BAL-rated systems. Recent innovations include FM Global approved products and syntactic foam cores (XFLAM) for enhanced fire performance. Market growth accelerated post-2020 with energy efficiency requirements and construction efficiency demands. Current Australian market leaders Bondor and Metecno continue product development focusing on thermal performance, fire safety, and sustainability improvements.
