Understanding R-Values in New Zealand Insulation

When considering insulation for your home, understanding R-values is crucial. The R-value measures the insulation's ability to resist heat flow, with higher values indicating better thermal performance.

What Are the Recommended R-Values in New Zealand? New Zealand's Building Code specifies minimum R-values based on climate zones:

R1.9

• Zones 1 & 2 (North Island):

  • Ceiling: R2.9

  • Wall: R1.9

  • Floor: R1.3

• Zone 3 (South Island and central North Island):

  • Ceiling: R3.3

  • Wall: R2.0

  • Floor: R1.3

  • 
    

Why Are R-Values Important? Higher R-values contribute to:

• Improved energy efficiency

• Enhanced indoor comfort

• Reduced heating and cooling costs

Conclusion: Selecting insulation with appropriate R-values ensures compliance with the Building Code and promotes a comfortable, energy-efficient home.
