ルをつぶすため、吸音性が低下する原因となる。However, although the sound-insulating flooring material using the heat-compressed polyurethane foam sheet is excellent in the performance of the flooring material, when it is applied to a concrete surface or the like, the urethane foam sheet Since the cell surface is exposed on the surface, resistance to slippage was strong and workability was poor. Further, when the curing of the concrete is incomplete, there is a problem that water oozes out and absorbs water from the cushioning material on the lower surface. Further, at the time of construction, the adhesive applied to the concrete surface infiltrates into the cushioning material to crush the cells, which causes a decrease in sound absorption.
