Description

Fibre?cement faced SIPs combine an EPS core with fibre?cement skins. Fibre?cement panel data list dry density ?1.6 kg/dm? (?1600 kg/m?), flexural strength about 4,640 psi (~32 MPa), and water absorption around 9%. These face-sheet properties underpin durability and impact performance; panel thermal performance depends on EPS core thickness.

SIPs technology originated in the 1930s USA Forest Products Laboratory research, with commercial adoption from the 1950s. Australian market entry began in the 1990s, with local manufacturing established in the 2000s. Fibre cement facing adaptation developed specifically for Australian conditions to address bushfire, cyclone, and termite requirements. Current Australian standards and manufacturing capacity support growing adoption in residential and commercial sectors, with ongoing development of higher performance cores and automated manufacturing processes.
