Technical information
Development on INSUL started in the 90's 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 20 to 25 years.
INSUL can be customised for particular materials (for instance a particular manufacturer's plasterboard).
