Clause H1 of the Building Code

Architects Desk

The New Zealand Building Code clause H1 sets criteria for the energy efficiency of New Zealand homes and buildings.

There are a range of options for showing compliance with clause H1 of the Building Code for residential or commercial buildings.

We offer our own free H1 calculation service when using Mammoth® thermal insulation. 

Our free H1 thermal calculations service

We offer a free H1 thermal calculation service where all you need to do is send us a set of your plans and we will take care of the rest. We'll measure up and calculate what is required using your plans and supply the information you need - you don't need to do anything else.

We provide the best solutions to save you time and money but more importantly, we know the cost and benefits of insulation as we’ve been manufacturing and supplying it for over 20 years.

In preparing your plans we can also suggest combinations of insulation products that more cost effectively deliver on your H1 requirements.
