The workhorse of the range: a 100% recycled PET panel that absorbs mid-to-high frequency sound and doubles as the finished wall surface. Because it is homogeneous throughout its thickness, cut edges need no edge banding — panels can be shaped, routed and printed without losing appearance.

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.
A4 swatches from the standard colour range are posted free of charge within 5 working days. Custom colours are matched against a Pantone reference.
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.
Why specify PET rather than mineral wool?
The panel is the finished surface as well as the absorber. There is no fabric wrap, no perforated facing and no edge banding, because the material is homogeneous through its thickness.
Can you print or route the panels?
Yes. CNC routing and UV printing are both available, and because there is no facing layer the cut edges stay clean.
Is the material genuinely recycled?
The fibre is needle-punched from recycled PET bottle flake with no added adhesive, and the panel can be recycled again at end of life.
