BRANZ staff are experienced in the thermal and insulation performance of buildings, and in the measurement of building energy efficiency. A two minute You Tube clip provides an overview of some of the services provided by our team.

We have contributed extensively to building code and standards developments and provide a full consultancy and testing service, in the laboratory and in the field, to assist manufacturers, designers and industry in general.

BRANZ has a registered testing facility for measuring the properties of thermal insulation materials.
