Investigação do comportamento de esquadrias utilizando a técnica da termografia de infravermelho

Abstract

The windows, in addition to the aesthetic requirements, have the function of guaranteeing the luminosity, the tightness (water and air), the safety and the acoustic and thermal comfort in the environments to which they are included. In order for these requirements to be performed correctly, it is necessary that the installation of these elements be carried out according to the appropriate construction techniques. This work, conducted a visual, photographic and thermal analysis to identify anomalies that compromise performance in windows. These analyzes occurred in the city of Alegrete / RS, in a reinforced concrete building, composed of two floors, and in an apartment, in a multifamily building, built with a system of concrete walls molded in loco. Through studies and analyzes obtained from the facades of reinforced concrete building, it was found that the pathologies discovered were always the same (horizontal cracks, tilted, staining and bubbles), with higher incidence in the east facade of the building. In the building of molded concrete walls in loco there were not observed pathologies in the region of the frames, however, it was analyzed thermal issues related to the connection between squaring-surface, to later make comparisons with the constructive system of reinforced concrete.
