なるので、５〜４０倍が好ましく、１０〜３５倍がより
好ましい。The foaming ratio of the foamed sheet 2 is preferably 5 to 40 times, more preferably 10 to 35 times, since the smaller the density, the higher the density and the lower the soundproofing property.
【０００９】また、発泡シート２の厚さは、配管用溝２

There is no particular limitation as long as the thickness is such that 1 can be formed,
The thickness is preferably 6 to 15 mm, because the soundproofness is reduced when the thickness is reduced, and it becomes easy to set when the thickness is increased. Here, the thickness of the foam sheet 2 means the distance from the lamination surface of the foam sheet 2 and the heat conductive sheet 4 to the lamination surface of the foam sheet 2 and the vibration damping sheet 5, that is, the pipe groove 21 is formed.

荷重が低下し、さらに沈み量が少なくなる。The floor heating mat of the present invention uses a closed-cell thermoplastic foam sheet as a base material and is therefore excellent in flexibility, heat insulation, impact cushioning, heat resistance and the like. Since the vibration-damping sheet having excellent rigidity is laminated, even when a concentrated load is applied, the amount of sinking is small and the soundproofing is excellent. In addition, by laminating the damping sheet on both sides of the closed-cell thermoplastic resin foam sheet, even if a concentrated load is applied to the surface, the load per unit area transmitted to the foam sheet is reduced, and the sinking amount is further reduced. .
