Insulation module It is a component of a multi band camouflage network, which functions to suppress the radiation intensity of thermal targets, change the direction of radiation transmission, reduce the probability of target detection, and improve the survival ability of targets. The traditional camouflage barrier insulation layer is a single piece of insulation cloth, which has the main disadvantage of easily generating new contour thermal features and increasing the weight and volume of the camouflage net, directly causing a significant reduction in the quick response of installation and dismantling during use. This insulation module has a small volume, good insulation effect, easy operation and use, and is easy to package and transport.
