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.

INSUL can be customised for particular materials (for instance a particular manufacturer's plasterboard).
