Does Mylar absorb heat?
Heat reflection: Because Mylar is impervious to infrared radiation, it has excellent heat-reflective properties, redirecting approximately 90 percent of radiant heat. This property can be used to reflect the sun’s heat and keep patients cool. Mylar withstands temperatures up to 150 °C (302 °F).
Does Mylar insulate?
It keeps your home cooler in the summer and warmer in winter. This type of insulation is commonly used to insulate roofs and attics. Mylar insulation reflects 97 percent of radiant heat in the home, potentially cutting home energy costs significantly.
