Libra Volumetric Baffles
Libra transforms the ceiling into a flowing, sculptural gesture. Curving and rising as continuous ribbons or segmented runs, these volumetric baffles bring movement overhead while quietly absorbing sound in busy, open interiors.
Each baffle is formed from 12mm ARCHISONIC® Felt [100% PET, 60% post-consumer], delivering dependable acoustic absorption [NRC 0,6; αw 0,65] alongside a B-s1,d0 fire reaction class. Sustainability is built in, with Cradle to Cradle, Declare and BREEAM Exemplary credentials supporting greener specifications.
Choose from 45 felt colours and 11 printed textures [including Riftcut, Terrazzo and Travertine], across three heights, with an optional integrated LED version that combines light and acoustics in one form. And when a project calls for something beyond the standard range, Akoesta's specialists can tailor Libra further, adding extra dimensions of freedom so the design fully expresses your intent.
Sold per linear meter. Available as continuous ribbons or segmented runs.
