摘要

The multi-layered structure (1) with at least two sheets (2,3,4) for heat and cold insulation involves sheets arranged in the effective area without direct contact with each other. Outside the effective area they are joined to each other at their edges, and this by means of distance holders. The sheets are of plastic, of metal or a combination of plastic and metal. Between the sheets a further layer is arranged of non-organic fibers. It may also be of paper, organic material, of powder consistency, be an adhesive layer, co-extrusion layer or similar.
