The decorative heat insulation structure comprises fasteners fixedly connected to a wall surface to be subjected to decorative heat insulation, wherein the fasteners comprise substrates which are parallel to the wall surface and are arranged in a spacing manner; edge closing slots extending towards two sides are formed in the substrates, and notches of the edge closing slots are parallel to the wall surface; the edge closing slots are connected with edges of decorative boards on two sides in a clamping manner; inner slots convexly extending towards a direction away from the wall surface are formed in the surfaces of the substrates; the bottoms of the inner slots are parallel to the wall surface; embossed connection blocks are arranged at the inner slots in every two adjacent upper and lower substrates; a space among the substrates, the decorative boards and the wall surface is filled with a heat insulation material; an embossed connection block is arranged between every two adjacent fasteners, so that the mounting intensity and the flatness are guaranteed; and by filling of the heat insulation material, gaps among the decorative boards, the substrates and the wall surface during mounting are effectively eliminated, so that the heat insulation performance of the external wall is improved. The construction method provided by the invention is easy and convenient to operate and high in mounting efficiency.
