The floatable element or pad including a body of floatable material, such as for example a low density polyethylene, or a high density cross-linked polyethylene, and the like, having a horizontal cross-sectional shape, such as hexagonal, enabling a plurality of such floating elements or pads to engage in flat surface-to-surface contact thereby providing a substantially gapless floating insulating cover. In one embodiment, the floatable element or pad includes top and bottom layers, side walls, and a plurality of thru-posts extending between the top and bottom layers and providing structural rigidity thereto, and wherein the top and bottom layers, side walls and thru-posts cooperatively provided a plurality of dead air spaces providing additional insulation between the liquid, slurry, semi-liquid or the like on which an insulating floatable cover comprised of such floatable elements or pad is comprised.
