A utilização de subcoberturas na construção civil para a correção do comportamento térmico de sistemas de coberturas cerâmicas:uma avaliação experimental

Abstract

This article deals with a field experiment, having tested foils as a measure of environmental correction of the thermal behavior of an inhabited construction. Considering the inexistence of suitable models that simulate quantitatively the effect of thermal isolation caused by light-coloured metal foils, in a thermal-barrier form, it was chosen to develop and use a measurement automatic empirical system, by means of the use of type T thermopairs and datalogger CR10X, Campbell Scientific. It was then registered and verified the fluctuations of the surface and air temperatures, registered inside the above mentioned inhabited construction, before and after the installation of double-faced bright foils, structured to resist mechanical strengths, as a way of reducing the thermal flow by the covering system: wood ceiling, Pinus elliottis, foils and ceramic tiles. Furthermore, it was used the climatic rythm concept for the choice of two measurement periods, in summer episodes, as well as of the typical days which represent this study, before and after the placing of foils.
