Knauf Insulation APAC announced the launch of their new H1 Calculator earlier this year — a free online tool designed to make H1 Building Code compliance faster and more straightforward.

The calculator helps builders, designers, and architects understand how insulation choices affect thermal performance and compliance under the NZ Building Code.

Key features include:

• Clear comparisons of how different insulation products influence performance
• Insight into thermal bridging and construction details
• Support for both the Calculation and Modelling Methods
• Guidance on window-to-wall ratios and other H1 variables
• Early identification of design shortfalls before submitting consent
• A simple, accessible way to test options without complex manual calculations

It’s a practical tool for anyone working to meet H1 requirements with confidence.
