While fire-rated steel windows carry a higher upfront cost than standard glazing, they are an investment in long-term building performance, life safety and compliance certainty. Increasingly, South Island construction, particularly commercial and multi-residential projects, cannot be consented without them. What Drives the Cost Achieving a certified fire rating requires specialist glass, reinforced steel joinery, thermal and structural testing, and installation to a documente

Specifying fire-rated windows is a process that begins long before installation. In the South Island, where seismic strengthening, densification and heritage upgrades are shaping the built environment, accuracy in specification is essential. Southern Windows works alongside architects, fire engineers and construction teams to ensure fire-rated steel systems are correctly selected, documented and installed to meet C/AS2 and AS1530.4 requirements.
