I haven't bought my foam yet, but I went to the store to try to figure out if the nominal thickness is the actual thickness. When I measured the edge of a 2" piece of Foamular 250, I found some variability, but they ranged from 1-13/16" to 1-15/16", so I was planning to call it 1-7/8", but I don't know if the edge measurement is the same as the thickness throughout the piece or not. For those of you that have worked with foam before, have you found that that the nominal thickness is the actual thickness or should I plan on something like my edge measurement?
Thanks, Tim
