Where can I purchase flexible 4 x 8 sheets of styrofoam (3/8 to 1/2 inches thick)?

Answer 1

As Kacky pointed out... styrofoam is NOT terribly flexible.

I buy some of my styrofoam from my local hobby shop under the Woodland Scenics brand. It comes in 2'x1' sheets in thicknesses from 1/4 to 2 inches.

I've also bought SOME styrofoam at my local Home Depot... it came in 4x8 sheets 3/4 and 1 inch thick.

I also ordered some extruded polystyrene foam (pink board) through Home Depot... easy to carve.

You can't. That would be like a custom order. Home improvement centers offer sheets that are 8' long and 2 inches thick. The hard part is the 4 inches wide. Depending on how much you need; purchase a sheet and cut it 4 inches wide yourself. Use a long straight edge to assist you in the cutting. Make sure you measure the width and mark it. Use a pizza cutter(yes a pizza cutter) to scroll/mark your line to be cut first. Check the width and afterward use a long razor knife to make the final cut. There are fabric cutters shaped like pizza cutters also. That may help you also. I suggested a pizza cutter first because most people have them and would save you money on purchasing the round fabric cutter.

Answer 4

Styrofoam is never flexible.

Do you mean foam like they use for costumes and upholstery? If you are lucky, there may be a foam wholesaler in your neighborhood. If not, an upholstery shop could help you, or you could go thru the internet
