Frank, having worked with sheet urethane foam (I assume common insulation with foil cover as sold at Home Depot, etc..),
do you know if the stuff is thermo-formable?
In other words, suppose you had 1/2" thick sheet urethane foam, peeled the foil off, put on a cookie sheet and into an oven at maybe 250 degrees for long enough for the heat to fully penetrate, then took the foam and pressed/vacuumed it against a compound curve shape like a basketball, would it drape and conform, keeping a permanent spherical shape as it cooled?
Or, would it just go back to flat stock shape?
