The acoustic fabric inlay Acustica is installed on the rear side of perforated ceiling panels and considerably improves the sound absorption. Acustica is available in different thicknesses and thus, it is suitable for diverse requirements. The inlay is completely made of polyester and has a density of 20 kg/m³ (± 10 %). It is completely free of mineral fibre and open to diffusion. Consequently, it is a sustainable solution to improve room acoustics.
