Program for calculating the sound insulation of separating components

INSUL is a program for calculating the sound reduction index or the impact sound level of separating components.
The calculations are carried out in one-third octave bands, from which the evaluated parameters are calculated.
INSUL is currently available in version v9.0 and with a multilingual user interface (including German, English and French).
INSUL is developed by Marshall Day Acoustics.

Range of functions:

  • Calculation of the sound reduction index R for rigid and flexible walls, ceilings and floor structures (calculation of up to three shells)
  • Calculation of the impact sound level for ceiling constructions
  • Calculation of rain noise (ISO 140-18)
  • Calculation of the sound reduction index of glazing (up to triple glazing, standard glass, laminated glass)
  • Calculation of the sound reduction index of sandwich panels and trapezoidal sheets
  • Calculation of sound insulation against external noise (DIN EN 12354-3)
  • Results as third octave, octave and weighted single values
  • Multi-layer shell structure (several layers, different materials and material thicknesses)
  • Various coupling models (timber and steel frames, fixed point connections, etc.)
  • Material editor (input of own material parameters)
  • Calculation of the composite sound reduction index
  • Auralization of the sound reduction index
  • Export of data to SONarchitect ISO and Bastian
  • PDF export

New in version v9.0:

  • Newly designed program interface with 3D graphics of the construction
  • Calculation of floating screeds with polystyrene or mineral fiber insulation board
  • Improved auralization, expandable user library for audio files; auralizations can now be saved
  • New connection types / frame types
  • Thermal insulation of glazing (in accordance with EN 673)
  • Database with metal or wooden uprights (standard sizes selectable from menu)
  • Calculation of pitched roofs
  • Better handling for large and small screens (interface elements can be customized according to your needs)
  • Available for Windows and Mac OS

INSUL - Demo version / 30-day license

The demo version of INSUL is freely available for download.
In demo mode, however, the material selection is randomized.

For practical calculations, we can provide a valid, time-limited software key on request, which can be used to test the full range of functions.
A new download is not necessary for this.
