SR485 Assessing the long-term performance of structural insulated panels (SIPs) in New Zealand (2024)

This research aimed to determine which method of ageing and mechanical testing offered the most practical measure of durability for SIPs having timber-based face layers to support the future assessment of these systems in New Zealand. The project also investigated the long-term performance of SIPs in a New Zealand context and the effects of ageing on the seismic performance of SIPs. Results are provided and discussed, along with recommendations made for appropriate methods for evaluating SIPs in the future potentially for compliance with the New Zealand Building Code.
