We engineer Insulated Glass Units (IGUs) that go beyond compliance to deliver best-in-class thermal performance, durability, and clarity.
Powered by global partnerships with innovators like Saint-Gobain and Technoform, and tested to the highest local and international standards, our IGUs are designed to perform in Australasia’s toughest climates.
Whether you’re specifying for residential, commercial, or architectural projects, you get a solution that’s proven to last and built to outperform.

FMIBI’s Insulated Glass Units (IGUs) are engineered to deliver exceptional thermal efficiency while helping you meet today’s stricter energy codes, such as New Zealand's H1 Energy Efficiency clause and Australia's NCC Section J.
Every unit is manufactured to reduce heat transfer, minimise condensation risk, and help projects achieve energy efficiency targets and building code compliance.
For projects requiring advanced solar control or enhanced insulation, we also offer a dedicated range of Low-E glass technologies.

Our IGUs last up to 3x longer

Our Insulated Glass Units use revolutionary XR Edge spacer technology in combination with Low-E, Ultra Clear glass for superior thermal performance, maximum clarity and a product lifespan up to three times greater than standard.

All FMIBI IGUs are tested in our IANZ-accredited onsite laboratory to ensure they meet or exceed local and international performance standards, including ASTM E2190, EN 1279, ISO 20492 and CEAKL rules.
Our testing simulates real-world conditions to guarantee long-term reliability and compliance, assessing:
  • Gas retention to maintain insulation performance over decades
  • Seal integrity to prevent condensation and moisture ingress
  • Thermal cycling to ensure stability across extreme temperatures
