BRANZ staff are experienced in the thermal and insulation performance of buildings, and in the measurement of building energy efficiency.

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.
