Abstract
A thermal insulation system 1, especially for low-temperature containers, formed of at least two multilayer mats 4 and 5, which are made from fiber mats 8 and are separated by a gas-tight film 6. The inner multilayer mat 4 arranged directly on the container wall 2 is filled with a gas, which cannot condense during operation and whose pressure can be adjusted to the actual ambient pressure. The outer multilayer mat 5 is filled with the ambient gas, generally air or nitrogen, and the pressure is adjusted to the ambient pressure. The multilayer mats 4 and 5 may be further subdivided by reflecting films 7 that are permeable to gas.
