Isolamento. Vedação vertical. Componente. Espessuras. Acoustic performance. Insulation. Wall partition. Component performance. Coating thickness. The performance of the buildings has become a growing concern of the builders, considering the demands of the users and the competitiveness of the real estate market; besides the Brazilian norm of performance of residential buildings. As one of these requirements, one can cite the sound insulation of vertical fences, which cause acoustic discomfort when deficient. The objective of the present work is to evaluate the compliance of the internal and external walls in the field concerning the criteria established by the Brazilian performance standard, analyzing the results obtained to the type of component and the total thickness and the coating. For this, data were collected in 15 multi-floor buildings, which used the following components: ceramic brick, ceramic block, concrete block or gypsum block. It was found that only 25% of the components comply with the standard for internal vertical seals. For external vertical seals, only 10% of the evaluated components comply with noise class II criteria and none with noise class III criteria. It was also verified that the concrete block presents a better performance for internal and external walls, due to its more constant behavior in the frequency range of 100 to 3150 Hz. The total and coating thicknesses that corresponded to the best acoustic performance, obtained in the sampling, were also identified. O desempenho das edificações tem se tornado preocupação crescente das construtoras, tendo em vista as exigências dos usuários e a competitividade do mercado imobiliário; além da norma brasileira de desempenho de edificações habitacionais. Como uma destas exigências, pode-se citar o isolamento sonoro das vedações verticais, que causam desconforto acústico quando deficiente. O presente trabalho tem por objetivo avaliar a conformidade das vedações verticais internas e externas em campo em relação aos critérios estabelecidos pela norma brasileira de desempenho, analisando os resultados obtidos em relação ao tipo de componente e às espessuras total e do revestimento. Para tanto, foram coletados dados em 15 edifícios de múltiplos pavimentos, que utilizaram os seguintes componentes: tijolo cerâmico, bloco cerâmico, bloco de concreto ou bloco de gesso. Constatou-se que apenas 25% dos componentes avaliados estão em conformidade com a norma, no caso das vedações verticais internas. Para as vedações verticais externas, apenas 10% dos componentes avaliados estão em conformidade com o critério de classe de ruído II e nenhum com o critério de classe de ruído III. Verificou-se também que o bloco de concreto apresenta melhor desempenho para vedações internas e externas, devido ao seu comportamento mais constante na faixa de frequências de 100 a 3150 Hz. As espessuras totais e de revestimento que corresponderam ao melhor desempenho acústico, obtido na amostragem, também foram identificadas.
