Abstract: A double-walled panel for building includes a main body defining an inner space and two opposite open sides, and being internally provided with spacing boards to divide the inner space into a plurality of chambers respectively having two opposite open ends; a working liquid being filled in at least one of the chambers; and at least two sealing covers being respectively provided on one surface facing toward the main body with insert portions for sealing the two open ends of each of the chambers. The double-walled panel may be used as a ceiling panel or a partition wall. The working liquid filled in the chambers not only helps in lowering indoor temperature in normal use conditions, but also helps in extinguishing fire when the building is on fire. The working liquid can also serve as drinking water for those who are trapped in a collapsed building during a disaster.
