Okay, serious question.
WHAT IS THE FOAM CALLED THAT YOU USE TO SCULPT ?
The term "foam" and "expanded foam" is used loosely throughout this thread, so I assumed that it must be some kind of expanded polystyrtene insulation foam.
But today I got a call from a heavily disappointed Odiwan72, who had visited a local building supply market due to a hint from me, but didn´t find the locally available STYRODUR (product name used in Germany for expanded polystyrene foam for insulating walls) being the same kind or similar material as the one you use for sculpting.
So, we need a clear technical description of the material to compare it to other brands and their insulation products. The usual short term for that stuff is "XPS" for "expanded polystyrene".
Dow Chemicals make something that is sold as STYROFOAM(blue colour) (another brand name that has been widely accepted as being an actual materials name), but they also use the names PERIMATE, FLOORMATE, ROOFMATE, respectively named for the intended use as perimeter insulation, wall insulation or roof insulation
.
The main difference in the appearance and quality is the level of insulation and pressure resistance the XPS has. And I think that is what the distinctive characteristics are that might help us finding a similar material.
I hope you guys can help.
It is that letter and number gibberish that is printed on the side or the top of the blocks/sheets you have that certainly will help us find the right material.
Thanks in advance,
Michael
