How do Emergency Blankets work?

Emergency Blankets are one of those thing that everyone should carry in an outdoor pack or survival gear bag. They are light weight and simple but how do they work?

I found this good reference http://adventure.howstuffworks.com/survival/gear/space-blanket.htm but the synopsis is that the special reflective film helps to reflect infrared energy. They also help to stop evaporative and convective heat loss.

Emergency Blankets have been around for some time but now manufacturers are making sleeping bags and heavier reusable blankets. For all types of blankets available at Barre Army Navy Store see http://shop.vtarmynavy.com/emergency-blankets-c470.aspx

Over the years we have had customers use these blanket for survival use but also to keep the alien's from getting them; as solar reflectors for their windows;  in between two layers of blankets to make a super blanket for insulating cold spaces and recently to reflect electromagnetic waves from transmitters. Let face it Vermonter's are a diverse group.

What would you use them for?

Even in a nonemergency situation, I put one under my sleeping bag in the winter to reflect body heat back to me and the cold back to the ground. Even with a Thermarest or similiar mattress, this keeps me a lot warmer.

When our furnace bit the dust several years ago, my husband and I built a walk-in-closet-sized room with conduit and emergency blankets. In it, we put all our small animals (birds, reptiles, rodents, etc), and a small space heater. The house was very cold, despite a space heater in each room, but the "animal room" stayed above 80° all the time, saving our tropical animals from the cold.
