Catedral Assembleia de Deus - Sede Nacional CONAMAD

BrazilBrazilCompany Name: Acústica do Brasil Indústria e Comércio Ltda

Project description

This Evangelic Cathedral was renovated to offer more visual and acoustic comfort to its visitors. The entire structure is oval and grandiose. The main challenges were its height of 25m, curved roof, and limited suspension points between the ceiling and the pre-cast concrete structure. Another important aspect of the installation was the alignment of the RIGITONE® boards and perforation to ensure a perfect finish. Great technical skills and knowledge of the usage and installation of RIGITONE® Ceiling systems were required in order to install the ceilings boards and optimize acoustics. The team also worked to mix reflection and sound absorption within a very complex curved shaped structure, which would not naturally provide this level of performance.
