Natural wood wool cement board (WWCB) acoustic panels, also known as fibrolite, made from sustainably sourced wood fibres bound with Portland cement. Sonablock 2.0mm delivers genuine sound absorption, Euroclass B-s1,d0 fire rating, and a bold, coarse surface texture suited to industrial and raw interiors. A sustainable, EU-made alternative to Heraklith and Troldtekt wood wool panels.
The 2.0mm coarse fibre gives the most open, tactile surface of the three fibre sizes - popular for loft offices, sports facilities, retail and anywhere an honest, unfinished aesthetic is intentional.
