The flat space acoustic body is a high-density microporous fibre absorber with edge sealing, hung horizontally by M8 safety rings, U-shaped rope buckles or angle-iron brackets. Broadband performance measured at 50 mm thickness reaches coefficients above 1.4 through the speech bands.

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 600 × 600 mm cloud sample with its suspension kit 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.
50 mm or thicker?
50 mm is the published data point; thicker bodies extend low-frequency control and are quoted per project.
How is the safety ring rated?
M8 rings with rated working loads; suspension calculations issued with shop drawings.
Horizontal or vertical mounting?
Both — horizontal clouds absorb the ceiling reflection; vertical mounts work in tall volumes.
Clear sound, clear mind.
