Análise comparativa térmica entre sistemas de vedação constituídos por paredes sanduíche em concreto armado com núcleo de EPS, alvenaria de vedação de blocos de concreto, tijolos solo cimento para fins de conforto térmico

Abstract

The current Brazilian civil construction market has several problems caused largely by the difficulty in implementing technological innovations that bring greater benefits to users and builders. In this scenario, it is necessary to search for materials that have superior qualities to those commonly used in Brazil, aiming to bring greater productivity, lower cost, more sustainability and also greater termal comfort for buildings. Thus, the constructive system using sandwich panels with an EPS core becomes an advantageous alternative in relation to the traditionally used methods, as it is a sustainable technology, more economical in the long and short term, lighter, and which brings greater thermo-acoustic comfort. In view of the potential of the method to bring better thermal comfort to buildings, this research focuses on building a sandwich wall prototype with an EPS core, and analyzing its heat transfer capacity with the aid of a thermal camera, comparing its results with Other masonry. Three types of masonry were analyzed, namely: The sandwich wall with EPS core, wall with cement and expanded clay soil bricks and wall with concrete blocks. Through the results acquired with the practical method used in this work, the concrete masonry with EPS core presented satisfactory results. It is also worth noting that, through standard deviation calculations for the results of temperature measurements that indicated the heat transfer of each prototype, the sandwich wall obtained more uniform data, proving to be a good alternative for masonry to be used in the municipality of Delmiro Gouveia, a city in the upper interior of Alagoas, which has high temperatures most of the year.
