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.
Technical information
Development on INSUL started more than 15 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 to 20 years.
INSUL can be customised for particular materials (for instance a particular manufacturer's plasterboard).
