We help you with Thermal Envelope H1 Calculations
The New Zealand Building Code clause H1 sets criteria for the energy efficiency of New Zealand homes and buildings.
There are a range of calculators that will check compliance of architectural building plans with the requirements.
When using Mammoth™ thermal insulation, we are happy to provide a free service to assist.
