Which would be better for insulating a box, duct tape, foil, card stock material, or heavy construction tar paper?
This is a project in school, we are working on Thermochemistry. Trying to figure out which would be the best insulator for a barrier box.(built from maple wood) The box is a model of a thermo-barrier system. We have to keep the temp. of the box above 0 degrees celsius for 15 min. and below 100 degrees celsius for over an hour.Any help, yea its alot, but i rlly need info and opinions.
