How does acoustic control differ between aluminum tongue and groove and gypsum ceilings?

Acoustic performance hinges on both surface design and backing materials. Gypsum ceilings rely on porous tiles or suspended baffles to absorb sound, but these systems can accumulate dust and degrade over time. Aluminum tongue and groove ceilings integrate perforated panels or micro-perforation patterns coupled with non-woven acoustic felts or mineral wool layers behind the metal surface. This assembly delivers controlled sound absorption while maintaining the sleek linear aesthetic favored in modern Central Asian auditoriums, from Moscow theaters to Bukhara conference rooms. Unlike gypsum tiles that scatter light and limit ceiling height, aluminum panels allow for continuous under-lighting and maintain clear plenum spaces for HVAC. Installers in Almaty report that properly designed aluminum systems achieve NRC (Noise Reduction Coefficient) values on par with traditional acoustic tiles. Furthermore, the metal’s non-porous finish prevents microbial growth within the acoustic layer, preserving performance and indoor air quality. For projects requiring durable, hygienic, and architecturally refined acoustic solutions, aluminum tongue and groove ceilings offer a compelling alternative to gypsum assemblies.
