ACOUSTIC FARBIC KIESEL

Acoustic fabric Kiesel – curtain textile for drapes & professional room acoustics

Kiesel acoustic fabric is a transparent, acoustically effective curtain textile designed for tailored curtain systems in demanding commercial environments. Made from 100 % FR polyester, the fabric remains permanently flame-retardant according to EN 13773, Class 1 – making it ideal for offices, seminar rooms, schools, hospitals and public buildings with high safety and functional requirements.

With a certified sound absorption value of αw = 0.55 at 100 % fullness (EN ISO 354, absorber class D), the fabric significantly enhances room acoustics and reliably reduces reverberation time. This supports speech intelligibility and concentration – especially in work environments, educational institutions and healthcare facilities where good acoustics are essential.

The light-transmitting and elegant texture makes Kiesel acoustic fabric the optimal solution for architects, planners and acousticians seeking to incorporate acoustic performance into aesthetically demanding designs.
