Construction of the vibration-damping and sound-insulating material The sound- damping and sound-insulating sheets obtained in the above Examples and Comparative Examples were applied to the second floor of a unit-type 2-by-4 house ("2U Home" manufactured by Sekisui Chemical, 6 tatami mats). The construction was performed as shown in FIG. That is, the vibration-damping and sound-insulating sheet 21 is laid on a particle board having a thickness of 20 mm, which is the floor base material 23, so that the cushioning layer is in contact with the contact area ratio shown in Table 1, and the floor is placed thereon. A 6 mm thick flooring material, which is a finishing material 22, is bonded using a vinyl acetate paste-based adhesive (trade name “Esdine floor tile” manufactured by Sekisui Chemical Co., Ltd.). A 40-mm finish nail was nailed at intervals of 150 mm and integrated, and a three-layer vibration-damping and sound-insulating material was fixed on the floor joist 24. Further, a sound absorbing material 25 is arranged between the floor joists 24.

The vibration-damping and sound-insulating sheet of the first invention is as described above, and comprises a vibration-damping and sound-insulating layer comprising a high specific gravity filler and a binder component containing synthetic resin, rubber or asphalt as a main component. By laminating the buffer layer made of the resin foam, the surface density is large, and the buffer layer has a sound absorbing effect, so that it has excellent vibration damping and sound insulating properties. Furthermore, when the above-mentioned vibration damping sound insulation sheet is constructed, by contacting the buffer layer with the floor base material, the tackiness with the floor is good and it is hard to slide, so that the positioning can be easily performed and the construction time can be greatly reduced. .
