A method for increasing the ability of a water surface to cool and freeze i s disclosed. The method includes the steps of providing a substrate surface adapted to support a layer of ice, and providing a water-impermeable flexibl e sheet on top of the substrate surface which supports the flexible sheet, the sheet including at least first, second and third layers. The first layer includes a heat reflective coating for reflecting heat transmitted from the substrate back into the substrate, a second or middle layer which may be an insulative layer, and a third or uppermost layer including a non-reflective coating to reduce heat absorption, and providing a layer of water or ice on top of the water-impermeable flexib le sheet whereby the flexible sheet enhances or lowers the temperature of the water on the surface by reducing the temperature transmission through the substrate surface and the upper surface or layer providing non-reflective properties to reduce heat transmission therethrough.
