The best sound insulation solution with our Acoustic Insulation Selector

Discover our new tool for your pipeworks

Why insulate your pipework?

Most industrial sites have kilometers of pipelines, a source of noise that can be very uncomfortable for workers.

There are multiple reasons for these noise disturbances, for example:


  • Fluid flow
  • Pipe diameter change
  • Termination of piping
  • Mechanical noise caused by equipment connected to the pipes (ejectors, pumps, valves or compressors)


Insulating will allow you to reduce the acoustic vibrations between the cladding and the pipe while absorbing the noise.

The sound insulation performance requirements of systems are defined in the standard ISO 15665. These requirements are intended to significantly reduce the noise produced by the pipes, valves and flanges of an installation.

Do you need help to find the best sound insulation solution for your pipework?

How does it work?

ISO 15665 standard defines the acoustic performance of three classes of pipe insulation: class A, B and C. The class “D” (Shell specification DEP has been adopted by industry professionals.

There are also 3 different groups of pipe diameters: 1, 2 and 3. Indeed, the insertion loss of sound insulation is related to the diameter of the pipe to which it is applied.

Now that we have all this in mind, here is how to use our tool:


  • Step 1:

Choose the acoustic class needed


  • Step 2:

Choose the diameter corresponding to the pipework you want to insulate


  • Step 3:

Choose the thickness of the insulation you want

How to interpret the results?

A selection of our products will be presented to you according to the criteria you have chosen. This selection is made according to ISO 15665.
To help you choose the best solution, our tool compares the entire selection according to two criteria:


  • Acoustic Insertion Loss
  • Thermal behavior (Thermal losses and Surface temperature)

Did you know...?

If you have pipes, valves or flanges that are already thermally insulated, they already benefit from a certain level of sound insulation!
