Polyester Fiber Acoustic Divider

100% recycled PET free-standing acoustic divider — 1800 × 600 mm standard, custom patterns and thicknesses available.
Fire: EN 13501-1 B–s1,d0 · GB 8624-2012 B1

Description

Polyester Fiber Acoustic Divider

A free-standing screen that gives an open-plan space its edges back. The panel absorbs sound from both faces while creating visual and acoustic separation — deliberation without walls.

Sound absorption coefficient

Measured to ISO 354 in a reverberation room, 100% polyester fibre, type A mounting.

Frequency (Hz)	125	250	500	1000	2000	4000
9 mm	0.13	0.63	0.83	0.95	0.75	0.69
12 mm	0.31	0.55	0.79	0.91	0.66	0.61

Peak absorption sits between 500 Hz and 1 kHz — the range that governs speech
intelligibility in offices, classrooms and open-plan spaces.

Applications

Open-plan offices and co-working floors
Public waiting areas and reception zones
Restaurants and hospitality

Options

Standard size 1800 × 600 mm; custom sizes available.
Patterns may be cut to your own artwork.
Thickness from 12 mm to 30 mm.

Material story

Panels are needle-punched from recycled PET bottle flake — a purely physical process with no
water discharge, no emissions, no waste and no adhesive. The porous structure makes the panel both
sound-absorptive and thermally insulative, and the finished panel is fully recyclable.

Frequently asked

Is the divider freestanding?
Yes. The 1800 × 600 mm panel stands on a weighted foot, so nothing is fixed to the floor or the ceiling.

Can it carry a printed graphic?
Yes. UV printing and CNC-cut patterns can be applied to either face.

Will it block noise between desks?
It absorbs the sound that reaches the panel rather than blocking it, which lowers reverberation across an open-plan floorplate — the effect that makes speech intelligible.
