Thermal and acoustical protection of a light construction

Claim 1

Method for thermally and acoustically protecting a construction in which a space is defined by a plurality of wall means, comprising, providing a substantially planar porous fluid conduit layer having intercommunicating pore-like cavities distributed substantially throughout the entire mass of the layer and two opposed surfaces in at least one of said wall means so as to be in a state of heat exchange with said space, directing water from a source of water whose temperature is different from the temperature naturally prevailing within the construction to undergo a bidimensional flow through said fluid conduit layer of intercommunicating pore-like cavities of the porous layer and substantially throughout the entire mass of the layer while maintaining said two surfaces of said layer in contact with means defining fluidtight surfaces, said flow of said water through said pore-like cavities being substantially without pressure and achieved by capillarity and thermally conditioning the space covered by the layer through which water flows.
