Aircraft insulation is a material that is used to insulate aircraft from the extreme temperatures that are experienced during flight. The three main types of aircraft insulation are: foil-faced insulation, fiberglass insulation, and elastomeric insulation. Foil-faced insulation is typically used in areas where there is a high risk of fire, such as the engine compartment. Fiberglass insulation is used in areas where there is a need for high thermal resistance, such as the cockpit. Elastomeric insulation is used in areas where there is a need for high vibration damping, such as the passenger cabin.
