Hoop Houses again

I'm installing a small hoop house (an Atlas 'cold frame') It's about 
36 ft long. I seem to remember that it's important to 'bury' sheet 
insulation on the outside of the greenhouse to prevent ice from 
creeping through the soil into the greenhouse if one is 4 season 
gardening. Furthermore, I seem to remember that those sheets of 
insulation should be canted at certain angles to further prevent 
pentration by the winter cold.

Can anyone tell me how think the insulation should be, how deeply it 
should be buried and what is the best angle to 'cant' it at?
