View SpecificationsIn response to the global transition towards sustainable architecture and climate resilience, New Zealand has implemented historic updates to the New Zealand Building Code Clause H1 (Energy Efficiency). These updates demand significantly higher thermal resistance values (R-values) across the country's six newly defined climate zones. For designers, developers, and mechanical contractors, this regulatory transition highlights the crucial need to source insulation materials that perform consistently under humid marine climates without structural breakdown.
Glass wool insulation has become the cornerstone of this transition. Composed of up to 80% recycled glass materials, glass wool leverages low thermal conductivity while maintaining high breathability. In New Zealand's unique climate, where dampness can compromise the thermal performance of building envelopes, selecting high-quality hydrophobic glass wool blankets and boards ensures the prevention of thermal bridging and moisture entrapment. This structural durability minimizes operational carbon and keeps heating and cooling costs low over the building’s lifecycle.
Important Industry Metric: The 5th edition of H1/AS1 and H1/VM1 has dramatically increased roof R-value requirements to R6.6 in all zones, pushing building designers to seek optimized, high-density glass wool configurations that fit standard truss footprints.

Understanding which material to deploy is essential for maximum energy efficiency. Glass wool uses an open-cell, fibrous matrix to trap air pockets, rendering it an exceptional choice for structural walls, roof cavities, and soundproofing applications. Elastomeric rubber foam, utilizing a completely closed-cell structure, acts as an impervious moisture and vapor barrier—essential for chilled water lines, cryogenic processes, and HVAC piping where condensation control is critical.
