Compressive loads—either caused by atmospheric pressure or developed during the application of multilayer insulations—are already known to reduce the overall effectiveness of insulation. Figure 1 shows the effect of compression on the heat flux through 15 multilayer insulations. The increase in heat flux after a compressive load of 2 psi has been reached is of comparable magnitude for all insulations tested. When compressive loads up to 2 psi are applied, the majority of the insulations show a heat flux about 100 times greater than the no-load condition.
