The emergency blanket is a handy and versatile item, essential inn your survival kit. This heat reflector can also be used to construct a shelter in itself. It’s a good item to have along when there is a shortage of natural construction materials at hand.
Remember, this emergency blanket is a heat reflector and nothing else. It is simply a thin sheet of plastic with a highly reflective material, usually on one side only. This side is the silver side. Because of the thin material used in this blanket, they are not particularly strong. They will shatter in windstorms, so they must be backed up with a heavier piece of material to prevent them from coming apart in the wind. If you do not have this sort of backing, the emergency blanket is not adequate as a shelter.
To construct the shelter, tie the cord between two trees or other uprights about three feet from the ground. Backing/reinforcing the emergency blanket with the 3 mil. Plastic, tape the combination over the cord all the way along the surface. Then, by straightening the blanket-plastic combination out and putting rocks, snow or other ground litter or debris on the far edge, you have completed a lean-to. The wind direction, at least initially, should be over the back of the shelter. Then, beneath the shelter put down another emergency blanket with the silver side up, put insulating material (pine boughs or whatever) on top, and build a fire out front. Now approximately 80 percent of the heat that goes into the shelter from the fire will be reflected down onto you from the top blanket, and heat will be reflected back up to you from the blanket underneath. In effect, you have a reflector oven which can “toast” you all night long. Another emergency blanket or piece of plastic thrown over the front of the shelter about one to one and one-half feet will help to hold the heat in.
