PROBLEM TO BE SOLVED: To provide a laminated sheet for warmth keeping and heat insulation which hardly causes warps even if a temperature difference occurs between front and back surfaces, and is excellent in lightweight properties.SOLUTION: In a laminated sheet for warmth keeping and heat insulation according to the present invention, net-like sheets having a basis weight of 20 g/mor more are laminated on both surfaces of a foam sheet. The laminated sheet for warmth keeping and heat insulation, formed in such a manner can suppress the occurrence of warps, for example, even if a temperature difference occurs between front and back surfaces of the laminated sheet. Consequently, the laminated sheet for warmth keeping and heat insulation hardly causes warps when used as a lid of a container, a bathtub, or a hot water tank and as a heat insulating material for a house, whereby warmth keeping properties and heat insulating properties of a container, a bathtub, a hot water tank, and a house can be improved. Since a material laminated on both surfaces of the foam sheet is net-like sheets, the laminated sheet for warmth keeping and heat insulation maintains lightweight properties.SELECTED DRAWING: None |
