Panel systems
Our timber acoustic families work across different frequency bands through combinations of hole geometry, substructure and backing. The values below come from accredited laboratory reports.
OA-Line
OA-Line — Grooved slat panel
Visible timber grain with strong mid and high frequency absorption.
- Absorption class (αw)
- αw 0,60 – 0,85 (Sınıf C–B)
- Reaction to fire
- B-s1,d0 (EN 13501-1)
OA-Perfo
OA-Perfo — Perforated acoustic panel
Broadband absorption — the safest choice for large volumes.
- Absorption class (αw)
- αw 0,70 – 0,95 (Sınıf B–A)
- Reaction to fire
- B-s1,d0 / A2-s1,d0 (EN 13501-1)
OA-Micro
OA-Micro — Micro-perforated panel
Invisible from a metre away, fully performing across the surface.
- Absorption class (αw)
- αw 0,55 – 0,80 (Sınıf D–B)
- Reaction to fire
- B-s1,d0 (EN 13501-1)
OA-Baffle
OA-Baffle — Baffle and slatted ceiling
An open-plenum ceiling that absorbs on both faces.
- Absorption class (αw)
- αw 0,75 – 1,00 (Sınıf A)
- Reaction to fire
- B-s1,d0 (EN 13501-1)
OA-Custom
OA-Custom — Bespoke and 3D surfaces
Geometry that is not in any catalogue: diffusers, curves, parametric surfaces.
- Absorption class (αw)
- —
- Reaction to fire
- B-s1,d0 / A2-s1,d0 (EN 13501-1)
