The blankets work to keep you warm by their very design. But as these blankets are not insulative, they do not prevent heat loss by conduction (heat-transfer). They can, however, be used very effectively against heat loss through convection.Dec 8, 2016
What is the purpose of a foil Mylar blanket and how should it be used?
An emergency blanket, sometimes referred to as a first aid blanket, space blanket, Mylar, thermal or weather blanket, is used in emergencies to reduce heat loss in a person's body caused by thermal radiation, water evaporation and convection.
What can mylar be used for?
Mylar, a type of stretched polyester film, is used in applications such as space blanket material, emergency blanket material, foil balloons, and Mylar tags and equipment labels. Obviously, the material is strong, versatile, and multifunctional.
What does a foil blanket do?
Space blankets, also referred to as Mylar blankets, keep your body warm by reducing heat loss. These blankets are made from sheets of metalized impermeable plastic material that reduce up to 90% of heat transfer from the body.
What was Mylar invented for?
photographic film
How do you use a Mylar blanket?
Do not press the Mylar blanket right against the skin. This will transfer your body heat through conductivity instead of radiation. Mylar blankets only reflect radiated heat. Leave some air space by putting on a jacket or normal blanket underneath the Mylar.
