Ceilings are the largest uninterrupted acoustic surface in most rooms, and treating them is the fastest route to cutting reverberation. These panels are designed to work with standard 12 mm, 24 mm and 30 mm exposed tee grid systems, so they drop into a conventional ceiling without special detailing.

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

Component test reports are issued to our manufacturing partners rather than to MST. Authorised copies, including laboratory and certificate numbers, are released with every quotation.
Cut samples of the 9 mm and 12 mm panels are posted free of charge, together with the ISO 354 data sheet.
Email your drawing, panel schedule or a square-metre count to sales@mstacoustics.com, or send the enquiry form on this page. We reply within one working day with pricing, lead time and freight options. Datasheets, colour charts and installation guides are collected in our technical resources library.
Does it fit a standard exposed grid?
Yes. Panels are supplied sized for 12, 24 and 30 mm exposed grid with a lay-in plain edge.
What does it weigh?
Approximately 1.85 kg/m² at 9 mm, so existing ceiling loads are rarely affected. Confirm against your structural allowance.
Are fixings included?
Lay-in panels need none. A screw-fixed version and a suspended ceiling-cloud version are also available.
Clear sound, clear mind.
