A thermal protection systems of a deployable aerodynamic decelerators includes a high temperature flexible insulation that utilizes a Flexible Gas Barrier (FGB) configured on an outside layer of a Hypersonic Inflatable Aerodynamic Decelerator-Thermal Protective System (HIAD F-TPS). The high temperature flexible insulation includes high temperature fibers and frits that melt upon exposure to elevated temperatures to prevent advection through the thickness of the high temperature flexible insulation. A coating may also be configured on an outside surface of the high temperature flexible insulation to also prevent advection. The frits may be configured through the thickness with different melting temperatures.
