Stone has been fundamental in construction since the beginning of civilization. Proper selection of rock materials contributes positively to environment by saving energy. Actual legislation is mandatory in what concerns Buildings Energetic Certification. Therefore, it seems relevant to discuss some thermal parameters as technological parameters. The purpose of this work is the evaluation of the rock finishing textures influence on heat transfer by temperature rate changes analysis along time. A comparative thermal behaviour analysis with different surface finishing was made. For this purpose common ornamental Portuguese stones used in building were tested for different types of finishing. Tests description is made, results are analysed, and some conclusions are presented. © SGEM 2014.
