It takes one day to construct the final finishing mortar The method for preventing noise between layers according to the fifth embodiment of the present invention is characterized in that when the case in which the sound insulating material is inserted is arranged on the floor of the upper part of the slab in the room, To the hot-water hose connection groove formed in the case, and then the final finishing mortar is installed within 4 minutes The comparison was found that could be constructed for the interlayer soundproofed completed very rapidly enough not be compared with Example 2 accordingly.
