Sonablock FireSafe Wood Wool Acoustic Panel 25mm · 1.5mm fibre · A2-s1,d0

Painted wood wool cement board (WWCB) acoustic panels, also known as fibrolite, made from sustainably sourced wood fibres bound with a higher proportion of Portland cement. Sonablock FireSafe 1.5mm is the Euroclass A2-s1,d0 non-combustible grade of the Sonablock range, for projects where the standard B-s1,d0 panel is not accepted. A sustainable, EU-made wood wool panel with a distinctive tactile texture. The 1.5mm fibre gives the coarser, more tactile surface of the two FireSafe fibre sizes - well suited to schools, auditoriums, and public spaces where a visible wood wool texture is wanted alongside A2 fire performance. Manufactured by Stiga RM - a PEFC-certified Latvian producer. Fire classification report issued by Kiwa (4243A / 1784 / 2026, July 2026).
