Thermal performance, specified and installed to suit the project.

Common questions

Questions builders and specifiers ask us.

• Why is the construction R-value lower than the product R-value?

  The product R-value is the batt on its own. The construction (or "as-built") R-value accounts for thermal bridging through the timber or steel framing, gaps and compression, so the assembly always performs below the bare product figure. H1 is assessed on the construction R-value, which is why correct product selection and install matter.

• Is a higher R-value better?

  Yes. R-value measures resistance to heat flow, so a higher number means better thermal performance. The right target depends on the element (wall, ceiling, floor) and the H1 climate zone the building sits in.

• Are you a Pink Batts installer?

  Yes. We are a commercial Pink Batts installer and also install Earthwool, Autex GreenStuf and Kingspan rigid board, choosing the product to suit the assembly rather than defaulting to one brand.

• What is H1 and which climate zone applies to my project?

  H1 is the energy-efficiency clause of the NZ Building Code. New Zealand is split into six climate zones, each with its own minimum construction R-values; the colder the zone, the higher the requirement. We install to the R-values your design and zone require and document them for sign-off.
