[0003] When the insulation layer is set on the bottom surface of the structural board, a non-disassembly insulation formwork is usually used, and the insulation board is used as a formwork for cast-in-place construction to connect the insulation board to the structure. This practice is usually to abandon the composite board in order to improve the bonding between the insulation layer and the structure.

This method uses wet construction. When pouring fine stone concrete, the insulation board will often warp or fall off from the structure due to the operator's trampling and mechanical pressure, resulting in poor molding quality and poor insulation against ground thermal bridges.
