NZS 4218 – Thermal insulation – Housing and small buildings

Specifies the thermal insulation requirements for housing and small buildings. It provides three methods for demonstrating compliance with the New Zealand Building Code: Schedule, Calculation and Modelling methods. It guides the achievement of minimum thermal resistance through balancing solar gains from glazing, insulation, and thermal mass, in order to significantly reduce the energy requirements to heat and cool buildings.
