The present invention relates to a sound insulation material between floors of a building, comprising: a first buffer member having an irregular unit wherein a concave unit and a convex unit are continuously formed on one side; a second buffer member which is formed in a flat plane shape having a predetermined thickness, of which the upper side is combined to the lower side of the first buffer member, and which has multiple fastening holes at regular intervals in one direction among the longitudinal and lateral directions; and a third buffer member in which the upper side is combined to the lower side of the first buffer member through the fastening holes. The present invention relates to a sound insulation material between floors of a building, capable of effectively buffering, diffusing, and eliminating noise from an upper floor to prevent the noise from the upper floor from being transferred to a lower floor in a multistory building such as an apartment or the like. |
