3.3 Ceramic Floor Tiles

Ceramic tiles are an extensively used material for paving, yet the incorporation of PCMs into ceramic tiles has been rather neglected, as observed by Pomianowski et al. [38], in their excellent review.

Cerón et al. [39] reported the production, development and experimental method, to test its performance, of a prototype tile. Nonetheless, the design of the tile was rather complex requiring numerous layers (top stoneware tile, metal sheet, a metal container with PCM and a bottom thermal insulation layer). The developed tiles were tested over a period of 60 days in one side of the solar house placed in Madrid that had door-window towards south. It was observed that high effectiveness was achieved for tiles close to the door-window where the direct solar radiation hits the tiles. The contribution of the tiles in the deeper location, further from the window, was very small. Therefore, the key conclusion was that the scheme should be limited to the portion of the floor that can receive the direct solar radiation. It has been considered essential to make a new prototype of tile that could be placed directly on the framework (see Fig. 3.2) and not on a technical floor, since this is a more usual and cheaper solution for housing. It was also considered necessary to develop the system in such a way that it met the acoustic requirements demanded by the Technical Building Code in Spain (CTE) [39].
