Double-layer hollow thermal insulation wall module for building

A double-layer hollow thermal insulation wall module for a building comprises a frame and a wall, wherein the wall comprises structural material layers, thermal insulation material layers and air isolation layers which are symmetrically arranged from outside to inside sequentially, as well as a single-layer isolation material layer located at the center; and the frame adopts a bar-type dimension lumber and is combined with the outer edge of the wall. The wall adopts a multilayer structure, and two air isolation layers are arranged between the two thermal insulation material layers and the isolation material layer. The wall adopting the structure has a stable mechanical property and an excellent thermal insulation property, the thicknesses of the wall and the materials which are required for the building achieving the same thermal insulation property are appropriately reduced, the wall floor space and the material cost are reduced, and the effective use area of the building is increased.
