How does acoustic absorption in slat ceilings outperform conventional mineral fiber panels?

In performance spaces from Tashkent Opera to Omsk universities, controlling reverberation is critical. Conventional mineral fiber panels absorb mid-frequency noise but require thick bulk to achieve NRC (Noise Reduction Coefficient) ratings above 0.7. Aluminum slat ceilings with perforated profiles and hidden acoustic backing deliver NRC 0.8–0.9 in just 25 mm thickness—enhancing ceiling heights and preserving architectural lines. The metal slats’ precision-drilled holes ensure uniform sound diffusion, while fiberglass or melamine infill absorbs broadband frequencies. This system resists moisture and fungal growth that can degrade mineral fiber in humid Kazakh summers. Installation around HVAC diffusers in Bishkek and Samarkand is straightforward, maintaining consistent acoustic performance without gaps. For modern lecture halls and conference centers, aluminum slat ceilings ensure clear speech intelligibility and balanced acoustics unmatched by traditional fiber panels.
