Análise comparativa dos sistemas construtivos alvenaria convencional e wood frame para habitação de interesse social

Abstract

The use of construction systems that combine durability, rapidity, concern with the environment and competitive cost with masonry, has been gaining more and more space in Brazil. To do this, one searches for effective construction methods that meet all these requirements, without increasing costs and maintaining the quality that the systems currently employed offer. The possibility of using new materials and alternative construction methods encouraged the development of this work. Therefore, the main objective of this work is to compare the construction methods of wood frame and conventional masonry in terms of cost, environmental impact, and thermal and acoustic comfort, in the civil construction of social interest, presenting these systems, their materials and construction stages with emphasis on the construction of low-income housing. As results, this work brings values of costs, labor necessity and time of construction of housing unit based on the two systems studied. In addition, it also presents the thermal and acoustic comfort that the systems provide, as well as the environmental impacts generated by them. The comparative analysis shows that the wood frame system is significantly more economical and more feasible, and brings less damage to the environment compared to the masonry system, which is more used in Brazilian constructions.
