Ultra-thin stone decorating plate suitable for heat preservation and installation method of ultra-thin stone decorating plate

The invention provides an ultra-thin stone decorating plate suitable for heat preservation. The ultra-thin stone decorating plate suitable for heat preservation comprises an ultra-thin stone plate, a VIP part boned on the inner side face of the ultra-thin stone plate through adhesives, and a bottom plate bonded on the inner side face of the VIP part through adhesives. A plurality of pits and protrusions or a plurality of strip-shaped grooves or grating-shaped grooves are distributed on the inner side face and the outer side face of the VIP part. If the ultra-thin stone plate is a flat plate, by means of the distribution of the pits and the protrusions or the strip-shaped grooves or the grating-shaped grooves, after a film bag with a core material is placed in a vacuum cavity and enters a normal-pressure environment after vacuumizing and sealing are conducted, the VIP part is a planar plate body; in other words, the tension of the film material on the inner side face of the VIP part and the tension of the film material on the outer side face of the VIP part can be consistent, and the VIP part is prevented from being bent.
