Hi Jan Willem,

In addition to the information that Lex gave i can tell you that we at
the Delft University of Technology have used this light isolation foam
(density up to 120) since a long time to mill models for our students,
taking part in a surface modelling course. The cost of the material is
about 20 to 30 percent of the OBOmodulan stuff.
Results can be good, depending on the requirements you have to meet.
As you seem to work around the corner here in Delft, maybe you would
like to drop in some time and have a look on the models we produce.
