The neatest use for space blankets that I've seen is in what Mors Kochanski calls a Super Shelter.A combination of space blanket, clear poly , uncoated nylon and natural materials.Natural material form the frame and platform,clear poly covers the frame and the one side that slopes toward you. Nylon is for a breathable door and the space blanket pinned inside on the ceiling as a fire refector. Think combination green house refector oven with the fire taking the place of the sun.
