A resposta correta é a alternativa (c) I, II e III estão corretas. Durlock® walls têm uma melhor isolamento acústico contra ruídos aéreos do que as técnicas de construção tradicionais. O desempenho acústico das paredes Durlock® é baseado no efeito massa-mola-massa. Os testes acústicos das paredes Durlock® foram realizados de acordo com a norma IRAM 4063. As paredes Durlock® são mais pesadas e menos flexíveis do que as paredes tradicionais.
