What are the acoustic performance benefits of using aluminum interior wall systems?

Aluminum interior wall systems can be engineered to deliver meaningful acoustic improvements for spaces where speech privacy and noise control matter—office suites in Riyadh, classrooms in Amman, or hotel guest corridors in Doha. Unlike plain metal sheets, modern aluminum interior wall assemblies combine multi-layer constructions: a visible aluminum face, an internal mineral wool or foam core, and resilient mounting clips or resilient channels that decouple the panel from structure-borne noise. This layered approach increases sound transmission loss (STL) and reduces flanking paths, improving privacy between adjacent rooms and corridors. Perforated aluminum panels with acoustic backer materials provide controlled sound absorption where reverberation must be reduced, such as open-plan offices or conference halls; perforation patterns and backing thickness are tuned to target mid and high-frequency ranges typical of human speech. Aluminum’s stable dimensions keep acoustic seals and joints tight over time, avoiding the gaps and cracks that can undermine long-term performance in gypsum partitions in dusty or hot climates like the UAE. For airport lounges and transportation hubs in Bahrain or Kuwait, specifying tested assembly ratings (STC or RW values) and partnering with manufacturers for on-site verification ensures the aluminum interior wall solution meets regulatory or client requirements. In short, aluminum interior wall systems offer flexible acoustic design—absorbing, isolating and sustaining performance in demanding Middle Eastern environments.
