Natural wood wool cement board (WWCB) acoustic panels, also known as fibrolite, made from sustainably sourced wood fibres bound with Portland cement. Sonablock 1.0mm delivers genuine sound absorption, Euroclass B-s1,d0 fire rating, and a fine, refined surface texture for demanding commercial and public interiors. A sustainable, EU-made alternative to Heraklith and Troldtekt wood wool panels.
The 1.0mm fine fibre gives the densest surface of the three fibre sizes - ideal for corporate offices, healthcare, and hospitality spaces where a clean, precise aesthetic is required alongside acoustic performance.
