I don't have any idea what aircraft insulation is....

but I have read here on the list of some who have cut up the foil/bubble
insulation that you can get in hardware stores... comes on rolls.... it's
about 1/4 inch think I think .... I guess they just push it into place when
they get to camp and raise the top.
