Thermal blanketing is used to keep satellite cooler or warmer, depending on what is needed. It acts like the insulation in your house: when it's hot outside, insulation keeps cool inside and when it's cold outside, insulation keeps warm air inside. Mylar [is] a very good material for thermal blanketing. Mylar is the trademark name for a polyester film plastic discovered and manufactured by the company DuPont. Mylar has many uses, including insulation, backing for magnet tape, balloons, and as a polyester film used to cover a metallic yarn. Mylar is also used for insulation in space suits. It is moderately expensive, and moderately durable.
