A package is adapted for assembly to form a panel unit to be deployed on a body of water to alter heat transfer to or from the water or to block evaporation. The package includes: (a) multiple frame sections adapted to be coupled together in end-to-end relation to provide a loop-shaped frame bounding an open zone, and (b) a flexible sheet sized for connection to the loop-shaped frame so as to extend crosswise of that zone.

In a panel unit to be deployed on a body of water to alter heat transfer to or from the water or to block evaporation, (a) a loop shaped plastic frame that is defined by end-to-end assembled frame sections, the frame bounding an open zone, certain of said frame sections being elongated, and others of the frame sections comprising short couplers telescopically interfitting ends of said certain sections, said certain frame sections being substantially straight, and exceeding four in number, said couplers having shallow angled elbow shape, and (b) a flexible sheet extending uninterruptedly cross-wise of and substantially completely across said zone and means attaching the sheet to said frame, said means comprising a flexible strand wound about said loop-shaped frame and passing through retainers in the form of eyelets on edge portions of the sheet, said sheet attached to the frame solely by the strand.
