About this product

Sonablock Fiber

Sonablock by Stiga RM are high-quality wood wool acoustic panels manufactured from spruce wood grown in Latvian forests and sourced from PEFC or FSC certified forestry. By combining spruce fiber with Portland cement, an elegant, durable and long-lasting material is created, offering excellent sound absorption properties, high fire safety and strong mechanical performance.

Thanks to their natural composition — wood fiber, cement, limestone and water — Sonablock panels are a sustainable and environmentally friendly solution. They are suitable for offices, schools, public spaces, residential interiors and technical areas alike. Available in various thicknesses, textures and colours, the panels offer extensive design flexibility.

The panels comply with EN 13168 and EN 13964 standards and are designed for interior use and semi-exterior areas with indirect exposure to weather conditions. They are certified according to FSC® and PEFC sustainable forestry standards.

Available in three thicknesses — 15, 25 and 35 mm — differing in weight, available lengths, fiber widths and edge profiles (pick the variant in the selector). Panel width is 600 mm for all thicknesses; custom sizes as per request. Colours: white (similar to RAL 9010), natural (similar to RAL 1015 or unpainted), light grey (RAL 7035), dark grey (RAL 7004) and black (RAL 9011); other RAL or NCS colours upon request.

Panels require no special maintenance: clean with a vacuum cleaner (brush attachment) or a lightly damp cloth. Use water-based paint for painting.

How it works

How it works

The open structure of mineralised wood wool absorbs sound energy instead of reflecting it, reducing echo and reverberation in the room. The absorption achieved depends on the panel specification, its thickness and the installation height; up to αw 0.85 according to the manufacturer datasheet.
