If you mean by that, that you used a box of 1 inch Styrofoam, you achieved an R-value
of 4. In my blurb of R values in the "permanent shelter" thread I explained originally,
that I would achieve an R-value of 15, with two layers of 1" polystyrene and fiberglass
batting between. Later, after I purchased the fiberglass I noticed the rated value of
R-12 and upgraded my estimate to a total of R-20, after I installed the fiberglass
batting and felt, that it would provide the rated protection fully. If you just used a 1"
polystyrene shell, you achieved only 1 fifth of the protection my basjoos got.
Best,
Olaf
