About the BRE

The Building Research Establishment (BRE) is a world class testing authority offering an extensive range of services covering the built environment.  All our acoustic ventilators are tested by BRE Acoustics and test reports are freely available below.  We also commission the BRE to calculate the equivalent areas of our boiler, stove and fire ventilators and background room ventilators giving you the confidence that the air space provided is accurate and verifiable.
