The utility model discloses a granite heat-insulation decorative slab, which comprises a decorative layer and a heat insulation layer, wherein the decorative layer is formed by a granite stone-like coating on one surface of the heat insulation layer, the other surface of the heat insulation layer is adhered to the wall via a bearing layer, and the heat insulation layer is an expandable polystyrene slab. The granite heat-insulation decorative slab is hung to the wall in a wet-sticking way. the expandable polystyrene slab is adopted as the heat insulation layer of the granite heat-insulation decorative slab, thereby the thermal conductivity is lower than 0.039W/(M,K), the apparent density is higher than 25kg/ m , the compressive strength is larger than 150kPa, and the flame retardant rating reaches to B2. The perfect closed cell honeycombed structure provides ultra-low water absorption, low thermal conductivity and fine ageing resistance, and the granite heat-insulation decorative slab scarcely ages during norm
