AS/NZS 4859.2 Calculations

Practical thermal bridging and insulation-system calculations aligned with AS/NZS 4859.2 methods.

What are AS/NZS 4859.2 calculations?

AS/NZS 4859.2 calculations are used to assess thermal performance impacts in building envelope systems, including thermal bridging effects where relevant to compliance pathways and product/system performance evidence.

These calculations are commonly used to support clear, evidence-based decisions in design and specification workflows where nominal R-values alone do not tell the full story of real system performance.
