Sistema de isolamento térmico de fachadas pelo exterior (ETICS): avaliação preliminar de viabilidade para sua aplicação no Brasil

Abstract

This research presents a preliminary study of a wall thermal insulation system, applied on the exterior, called ETICS. It aims to evaluate the feasibility of the introduction and widespread use of the system in the Brazilian market. Through an analogous method, it is pointed out, in various areas, constraints such as rules, climate and economy, and the gains and problems encountered and reported by other countries that are using the system on a regular basis. Thus, this research concludes that in terms of the applied materials, they exist in Brazil, needing only to be adapted. In terms of techniques, there should be implemented a standardization method and calculations should be made by experts. For legislation issues, related to thermal insulation in buildings, only a few viable solutions are contemplated, and ETICS has the potential to become one. On climate issues, the ETICS proves to be adaptable to various temperature changes, whether extreme cold or heat. Economically, it was estimated an increase in the total cost of the building, overall, considering the type of current typical construction. Culturally is expected an easy acceptance, because the appearance of the façade coated with ETICS is similar to a finish painting on simple plaster.
