<p>Multilayer metal foil pads or panels (10) for heat or sound insulation or shielding comprising two or more corrugated metal foil or metal sheet layers (C) wherein a flat metal foil or metal sheet layer (S) is positioned between each pair of corrugated layers (C). The corrugated layers (C) and/or the flat layers (S) may be embossed, patterned or textured to enhance performance of the pad or panel. A preferred pad or panel (10) comprises an embossed, patterned or textured flat exterior layer (E) adapted for contacting the surface (12) to be insulated or shielded to provide air space between the pad or panel (10) and the surface (12) and to separate the first corrugated layer (C) from the surface (12). Methods are provided for making the pads and panels (10), which are useful in automotive applications, food cooking devices and other uses.</p> |
