[0044] In some embodiments, in combination with Figure 1 As shown, the thickness of the external thermal insulation layer 11 is D1, wherein D1 = 100 mm ± 4 mm. For the external thermal insulation layer 11, a thickness of 100 mm can provide sufficient thermal insulation effect under most climate conditions, reduce building energy consumption, and at the same time, not be too thick to affect the construction of the wall structure 1, thereby balancing the thermal insulation performance and wall construction.

[0045] In some embodiments, in combination with Figure 1 As shown, the thickness of the internal thermal insulation layer 13 is D2, wherein D2 = 20 mm ± 2 mm. For the internal thermal insulation layer 13, a thickness of 20 mm can form an effective thermal insulation barrier in the indoor space, slow down the loss of indoor heat, and at the same time, not be too thick to affect the utilization rate of indoor space, thereby maximizing the thermal insulation and benefits.
