Are space blankets warmer than regular blankets?

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.

Do Mylar blankets really work?

Mylar prevents heat loss from radiation, evaporation, and (because it is windproof) convection. Traditional blankets prevent heat loss from convection and (to a lesser extent) from conduction. Thus, if you combine a Mylar blanket with an insulating blanket, you will prevent all forms of heat loss.
