<p>PROBLEM TO BE SOLVED: To provide a sheet-like molding useful as a floor substrate material containing ash as a component provided with performances such as flexibility, size stability, lightweight and sound insulation. SOLUTION: The floor substrate material is formed by laminating a sound insulation material comprising a composition contained at the ratio where a binder comprising a synthetic resin or rubber as a composition to ash of 100 pts.wt. is 10-95 pts.wt. and cement is 3-60 pts.wt. on at least one face of a sheet- like base material and is joined to be integrated as the sheet-like molding.</p> |
