A suspended ceiling has a grid formed from a number of parallel first support sections and a number of parallel second support sections extending perpendicular to and between the first support sections. The support sections are extruded from a metal having good heat conduction properties and are adapted to be interconnected by cruciform connectors thereby to form a lattice of regular quadrilaterals. The grid carries a pipe through which flows a heated fluid and which extends in a serpentine path along an upper surface of the first support sections and along upper surface of the second support sections at the edges of the ceiling. The pipe is secured in good heat conducting relationship to the first support sections by a series of clips. Ceiling panels made from a heat-insulating material occupy the spaces between the first and second support sections. The supporting grid thereby constitutes a heating system for the room below the ceiling.
