Abstract: The objective of the present study was to evaluate the effect of using different types and compositions of materials with insulating characteristics in the production of concrete tiles, in order to improve the physical, mechanical and thermal characteristics of the tiles. The insulating materials used were vermiculite in proportions of 5% (TAV5) and 10% (TAV10), polystyrene in the proportion of 5% (TAI5 )and additive incorporated with air in proportions of 5% (TAA5). Tests were conducted to determine the physical properties (dimensions, water absorption and permeability), mechanical (flexural strength at break) of thermal and concrete tiles. The physical, mechanical and thermal of different tiles were compared to data obtained from the reference tile (TAN) and evaluated based on the minimal criteria established by the NBR 13.858:2 (ABNT, 2009). Based on the results of the physical properties, it was found that all treatments met the requirements of the relevant standard in the country. As regards the mechanical properties, various tiles in the flexural tensile strength was lower than the recommended minimum. The incorporation of materials with insulating characteristics of concrete tiles showed good efficiency in reducing the temperature of the tiles.
