A double-walled panel for building includes a double-walled main body (1) defining an inner space and two opposite open sides, and being internally provided with a plurality of spacing boards (11) to divide the inner space into a plurality of chambers (12), and each of the chambers having two opposite open ends (121,122) at the two open sides of the main body; a working liquid stored in the chambers in the main body; and at least two sealing covers (3) for sealing the two open sides of the main body as well as the two open ends of each of the chambers. The double-walled panel may be used as a ceiling panel or a partition panel. The working liquid stored in the chambers not only helps in lowering indoor temperature in normal use conditions, but also helps in putting out fire when the building is on fire.
