Sandstone acoustic panel bonds mineral granules with eco, fire-resistant resin into an irregular-pore porous absorber. Its cavity combines porous and resonant absorption for a wide working band — and the mineral finish supports large-area seamless installation with real decorative presence.

Octave-band average of the 250–2000 Hz bands (NRC) ≈ 0.60. Coefficients are quoted for the mounting described above; a different cavity depth or backing moves the curve, so confirm the build-up with us before fixing the specification.
Hotel lobbies, museums, offices, corridors and anywhere a seamless mineral finish with real absorption is wanted.

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.
A sample panel of each sandstone finish is despatched free of charge within 7 working days.
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.
Is the surface really seamless?
Yes — joints are filled and the sound-transparent primer/topcoat system is scraped over the whole field.
Can I use my own paint?
Topcoats must remain acoustically transparent — we approve or supply the coating.
What substrate is behind it?
A board base screwed to keels, with acoustic cotton in the cavity.
Clear sound, clear mind.
