Insulation and thermal performance testing

BRANZ is experienced in testing the thermal performance of buildings and insulation products and measuring building energy efficiency. We provide a full consultancy and testing service, both in the laboratory and in the field.

We provide insulation and thermal performance testing.

What we do

BRANZ research has contributed extensively to development of Building Code requirements and standards for thermal performance of building materials. Through our consultancy and testing services, we assist manufacturers, designers and the wider industry to improve the thermal performance of insulation materials and of buildings.

Why work with us?

BRANZ is accredited by International Accreditation New Zealand (IANZ) for measuring the properties of thermal insulation materials using the test method in:

The properties we are accredited for measuring include:

  • thermal transmission properties of thermal insulation and other materials
  • thermal resistance of low-density batt and blanket-type mineral fibre insulation
  • thickness and density of blanket or batt thermal insulation.
