✦ Synopsis

There is a lack of reliable information on the application and performance of pipe lagging, even though this method of noise control is widely used to reduce noise radiating from exposed pipework.

To provide this information a thorough investigation has been run on pipe lagging materials. The noise-reducing properties of over 120 combinations of material were evaluated.

Results from this study show that lagging can be a very good form of noise control, provided it is correctly applied. Both inner layer and outer cover contribute to the overall performance. This paper explains how each element contributes to the performance and discusses the effects of material properties on these contributions.

The factors limiting the performance o flagging in practical situations are shown to be poor fitting, exposed flanges and physical coupling between the outer cover and the pipe.

Performance figures for commonly used laggings are of particular interest. Measured values for mineral wool with various outer covers are included for this reason.
