Formance

Formance is New Zealand’s leading manufacturer of Structural Insulated Panels (SIPs), purpose-built for high-performance building envelopes. Manufactured in Christchurch using Oriented Strand Board (OSB) and Expanded Polystyrene (EPS), Formance panels deliver exceptional airtightness and thermal performance, two critical pillars of Passive House design.

With near-zero air leakage, no thermal bridging, and R-values well exceeding code minimum (including graphite-infused EPS options for even higher performance), Formance SIPs provide a proven pathway to Passive House certification. CodeMark certified to the New Zealand Building Code, panels arrive pre-fabricated and precision-cut, enabling faster, tighter builds with less on-site waste. Born in post-earthquake Christchurch, Formance is passionate about making warm, healthy, energy-efficient homes the standard across Aotearoa.
