Construction

The AkuWall Felt differs from the classic AkuWall with a construction made entirely of certified acoustic felt.

    The absorbing material forms the entire surface of the element and is responsible for soaking up sound.

  2. 4 × 4 cm felt slats

    Each slat is 4 cm tall and 4 cm wide, which builds a clear spatial rhythm.

  3. 2.5 cm spacing

    The repeatable spacing keeps the slat layout tidy on the 240 × 40 cm module.

    The construction contains no hard parts or sharp edges and can be trimmed with a utility knife.

Le rendu feutre est très moderne sur le mur et la réverbération a baissé. Pose facile juste un prix au mètre carré un peu élevé à mon goût.

The felt slats look sleek on the wall and noticeably soften the room. Easy to put up and the colour options are great, very happy with it.

Miękki filc wygląda bardzo nowocześnie i ładnie ociepla wnętrze sypialni. Pogłos wyraźnie mniejszy, a montaż banalnie prosty.

Der Filz wirkt modern und edel an der Wand, dazu schluckt er den Nachhall spürbar. Montage war einfach und die Farben sind schön.
