Product Description

Acoustic folded PET slats of various sizes and colors designed for wall cladding. They are inserted into a metal ridge and are removable. Optional fillers between the slats are available to achieve a homogeneous appearance. Excellent acoustics, pleasant felt material with endless options for custom design and colors. Create your own look with variations in width, depth, and color.
They are spatial acoustic elements composed of vertically or horizontally oriented slats for walls. The combination of different widths and heights of slats is a distinctive design feature. The slat height is 2400mm with a width of 40mm. Felt Line felt slats are easily shaped with a sharp knife, allowing for various design compositions with different lengths. They are suitable for office communities, shops, and restaurants—only limited by your imagination. The Felt Line panel is designed to reduce noise levels and is an effective solution for sound absorption, also reducing reverberation time for household noise.
