Sistema construtivo em painéis monolíticos em poliestireno expandido (EPS) em casa residencial - estudo de caso

Abstract

Among the new materials applied in civil construction is Expanded Polystyrene (EPS), which is a rigid cellular plastic originating from the polymerization of styrene in water, coming in different forms. The Construction System in Monolithic Expanded Polystyrene Panels (EPS) is made up of EPS panels with steel mesh, connected to the foundation by means of starters and subsequently covered by a structural mortar. This system has credibility regarding the functionality of its structural behavior, thermal comfort and impermeability, attested by the Technological Research Institute - IPT of São Paulo. As there is no specific standard for this construction system, NBR 7480 (ABNT, 2007), SINAT n°011 and NBR 11173 (ABNT, 1990) are used. The construction system has the advantages of speed in construction; thermoacoustic insulation; lower environmental impact and reduction in the weight of the structure, without reducing the resistance of the building, and presents as disadvantages, the need for specialized labor and maintenance and special care, in relation to electrical installations. In the cost comparison made in relation to conventional 9x19x29cm ceramic brick masonry, there is a saving of around 50%.
