Smarter. Stronger. More Sustainable.
A Natural Upgrade from Conventional SIPS
Build faster, stronger, and more sustainably with Hiberna Modular pre-fabricated straw panels. Our precision-engineered system is designed for New Zealand conditions and delivers unmatched performance in speed, strength, and environmental impact.
The Better Choice for Structural Panels in New Zealand
Looking for a sustainable building solution that outperforms conventional SIPs in thermal performance, moisture protection and design flexibility?
Conventional SIPS (Structural Insulated Panels) have long been praised for speed and insulation. But they come with compromises – especially when it comes to breathability, moisture resilience, and long-term sustainability.
Our panels are New Zealand’s next-generation prefabricated building system. Designed for high-performance homes, and healthy living environments. Offering all the benefits of SIPS, without the downsides.

Hiberna vs Conventional SIPS: What Sets Us Apart?
Insulation
We use natural fibre insulation (straw) that’s breathable, non-toxic, and safe for occupants. Conventional SIPs typically rely on rigid foam (EPS or PIR), which is non-breathable and derived from fossil fuels.
Moisture Control
Our fully weather-sealed, vapour-open system helps prevent condensation and mould. In contrast, conventional SIPs can trap moisture inside the panel, increasing the risk of long-term damage.
Thermal Performance
The panels are engineered to meet or exceed Passive House standards, offering outstanding thermal values. While traditional SIPs offer good insulation, performance depends on the foam used and may degrade over time.
Sustainability
We prioritise low embodied carbon and renewable materials throughout our panel system. Conventional SIPs use synthetic foam cores with a higher environmental impact.
Compliance
Hiberna Modular Panels are in the process of achieving CodeMark certification for full compliance across New Zealand. Conventional SIP systems vary by supplier and may not have full national certification.
Sustainable Building,
Done Better
Hiberna Modular Panels are made from renewable, breathable, high-performance materials that help regulate temperature and humidity naturally. That means
-
A healthier home environment
-
Lower lifetime energy costs
-
Reduced carbon footprint
-
Superior performance in all New Zealand climates
Built for New Zealand builders & architects
We’ve worked with leading architects, builders, and developers across Aotearoa to design a smarter system:
- Pre-Fabricated for Speed – Panels are delivered ready to install with millimetre accuracy.
-
Superior Insulation – Designed to meet or exceed NZS 4218 and international passive house standards.
-
Healthy Homes – Non-toxic, breathable panels help regulate indoor moisture and temperature.
-
Minimal Waste – Pre-cut and pre-finished to reduce site waste and build time.
Trusted by builders across New Zealand.
“The Hiberna system gave us the speed of prefab without compromising on design or sustainability. It just made sense.”
