The aim of the present study is to develop and analyze a prototype of porcelainized stoneware tiles fixing system in ventilated façade based on existing technology in the country. Moreover, the aim is to analyze aspects as the effects of holes execution operation in the ceramic material, besides properties related to the interaction of the tiles with expander screws for their fixation, as maximum torque for tightening these screws and union strength between screws and tiles. In this way, a procedure for no-pass holes execution in the tiles was developed, where the expander screws are inserted. Analysis using scanning electron microscopy shows that grooves are introduced and pores are opened in holes surface with the operation of holes execution. Testing methodologies for determining properties such as maximum torque for tightening of the expander screws for tiles fixing and union strength between these expander screws and tiles were developed. In the panel of the ventilated façade prototype, executed in a building in the real conditions (Tijucas, SC, near to Florianópolis - latitude 27º03'S, longitude 48º45'W), it was not verified pathologies during a visual analysis period of approximately 2 years.
