In the solid rammed earth wall, the internal insulation structure can be used for internal insulation. The method is as follows: implant steel bars in the solid rammed earth wall and reserve a gap in the thickness of the polystyrene board, place the insulation board that meets the design requirements in the steel bar, fill the rammed earth material between the insulation board and the formwork for compaction, and During the process, both sides of the insulation board should be filled with soil and tamped at the same time to ensure that the insulation board will not be squeezed to one side.

In the rammed earth decorative wall, the internal insulation method can be used to complete the insulation construction of the wall. Construction method On the other side of the non-rammed earth decorative wall, the method of internal insulation is used to construct thermal insulation mortar or thermal insulation cotton. Afterwards, it is decorated with paint.
