Structural plate for light engineering has inner core layer with outer cover layers having integrated mineral fibre plates as fire protection layers

摘要

The structural plate comprises an inner core layer (2) with outer cover layers (3,4) in sandwich structure so that the plate has an integrated mineral fibre plate (M) forming a fire protection layer. Mineral fibre plates can be provided either side of the inner corer. The corer layer can be formed from a paper honeycomb covered on the top and bottom surfaces with stuck-on mineral fibre plate.
