5.2.2 No-noise bracketing – Double bracket – lower than 10 dB(A)
The no-noise type installation makes use of the same “Wavin low noise bracket”, only difference in this installation is the stacked
installation of the fixed bracket. The sliding bracket is the same as in the Low noise installation (see paragraph 5.3.1.). Each Wavin
low noise bracket contains a rubber inlay that has foam sidewalls. The stacked installation offers further acoustic decoupling, for
increased noise performance. The stacked installation consists of a sliding bracket that is mounted to the wall (not exceeding the
treaded rod distances in table 22) and a fixed bracket that is mounted to the pipe. In final installed form, the fixed bracket is carried
by the sliding bracket.
In the no-noise installation, the distance washers make sure that in any situation, the clamping force on the pipe is perfect. This re-
sults in minimal structure borne sound transmission. The distance washers also prevent over-tightening of the brackets, which could
otherwise result in a reduction of sound performance.
