Abstract:
1. A material comprising at least one of a thermal or sound insulation material comprising at least one inner layer (A) comprising at least one of temperature invariant or temperature resistant material as decoupling layer showing a two or three dimensionally structured surface on at least one side, at least one layer (B) as intermediate temperature gradient layer comprising at least one of temperature invariant or temperature resistant material, and at least one outer layer (C) as insulation layer comprising an expanded polymer blend wherein layer (A) has a thickness >10 micron, layer (B) has a maximum thermal conductivity of 0.1 W/mK, and a thickness between 5 and 50 millimeters, and the polymer blend of layer (C) is expanded to a closed cell content of at least 80%.
