摘要

The vacuum isolation panel useful in refrigerators, in freezer and in building and construction industry, comprises a inner component (1), which has cavities (1.1) arranged in two rows lying one above the other and which is provided with a covering (2) consisting of a thermoplastic material from renewable raw materials, and a laminate applied on the covering. The cavities of the upper row are arranged opposite to the cavities of the lower row in laterally movable manner. The laminate consists of glass nonwoven and/or glass fabric and/or metal foil and/or heavily inflammable paper. The vacuum isolation panel useful in refrigerators, in freezer and in building and construction industry, comprises a inner component (1), which has cavities (1.1) arranged in two rows lying one above the other and which is provided with a covering (2) consisting of a thermoplastic material from renewable raw materials, and a laminate applied on the covering. The cavities of the upper row are arranged opposite to the cavities of the lower row in laterally movable manner. The laminate consists of glass nonwoven and/or glass fabric and/or metal foil and/or heavily inflammable paper or a color pigmented material. The element is connected with a vacuum pump. The internal component consists of a honeycomb material. The cavities of the honeycomb material are separated by partitions having openings. An independent claim is included for a procedure for the production of vacuum isolation elements.
