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?
