ABOUT INSUL
With extensive drop down menus to select materials, and simple choices for construction details you can quickly evaluate different constructions. INSUL shows a picture of your construction and a graph of the 1/3 octave TLs.

You can download a trial version of INSUL to evaluate for yourself. Should you decide to purchase INSUL you may contact Marshall Day Acoustics Ltd, or one of our distributors.
NEW FEATURES (version 7.0)
INSUL undergoes continual development. The new version includes triple panels, a powerful new materials editor (with regional and user databaases), an auralisation feature and a guide to flanking limits.
TECHNICAL INFO
Development on INSUL started more than 10 years ago, based on research in the USA by Ben Sharp and others. It has gradually developed into a unique tool that incorporates the best of many research papers published over the last 15 years. INSUL can be customised for particular materials (for instance a particular manufacturer's plasterboard).
EXAMPLES
Of course such a program is of no use if it doesn't actually predict the performance of walls accurately. We have prepared a number of comparisons between predictions and measurements to give some idea of INSUL usefulness. A summary of a study on overall accuracy is shown on this page
