O segredo do Silêncio! Vidro e Barulho: qual relação? Blindex #construcaocivil #podcast #arquitetura

In this short podcast segment, Speaker A explains how the acoustic performance of glazing depends on the thickness of glass panes, with thinner (4 mm) and thicker (6 mm) sheets attenuating different frequency ranges. He introduces insulated glass units (IGUs) – two glass sheets separated by a spacer (aluminum or flexible) that creates an internal air cavity – as a way to markedly improve sound isolation. Aural performance also hinges on structural factors such as the type of frame (cachilho) and the surrounding masonry, with specifications often noted as 4+4 or 5+5. Speaker B reacts, noting the insight about thickness‑frequency interaction, recounts his own experience using an air‑sandwich solution, and highlights practical challenges like creating an acoustic escotilha, describing the process as “a bit tricky but rewarding.” The dialogue underscores the need to match glass type and installation details to the intended acoustic goal of a space.
