Bildspec Passes Stringent CSIRO Acoustics Testing
Bildspec Operable Walls have recently performed testing on its suite of operable walls with the aim of determining what acoustic rating could be achieved from its frames, seals, insulation types, wall materials and densities, and overall construction methods. This testing was carried out in February 2020 at CSIRO’s acoustic testing facilities in Clayton, Victoria. Testing was in accordance with AS 1191
Through consultation with PKA Acoustic Consultants and using the combined knowledge of Bildspec’s staff (which equates to 100+ years of operable wall experience), Bildspec has been able to achieve some very strong results at the CSIRO. Testing in accordance with AS1191 requires the test wall to be opened and closed 10 times without intervention, to the seals or components before the test. This stringent form of test means the wall will perform better in the real world, compared to our competitors walls. Through many tests and trials we are now able to provide walls that are rated to 45Rw, 47Rw, 49Rw and 52Rw, in accordance to AS1191, all out of our 100 series walls.
Bildspec have worked closely with PKA Acoustic Consulting in the R&D work that has gone into the construction of our operable walls. PKA Acoustic Consulting commenced operation,
as Peter R Knowland & Associates, in 1968. From then until the present, the firm has handled well over 8000 acoustic projects spanning a wide spectrum of the boundaries of acoustic consulting.
The skills of this practice are widespread extending from domestic air conditioning to industrial noise, environmental noise control and complex vibration isolation solutions.
