The new Sonex plywood family

Choose the Sonex family of sound insulation plywood products wherever proper sound insulation is needed: from the floor and wall structures of buses and trains to various construction uses.

Sonex: Composite sandwich plywood panels that include technical heavy layer (Isokon) inside the birch plywood to improve sound insulation. Sonex panels possess excellent characteristics for reducing the engine noise of buses and other large vehicles.
Sound reduction index. (Rw (dB) 32 dB up to 33 dB).

Sonex Light: Same structure as Sonex but Sonex Light contains cork rubber (Amorim) to improve sound insulation. Sonex Light is the choice for vehicles where proper sound insulation and lightweight structure are key points. The low weight also has a positive impact on the vehicle’s consumption and carbon dioxide emissions.
Sound reduction index. (Rw (dB) 30 dB up to 31 dB).

Sonex Double: Combines the best properties of Sonex Light and Sonex, providing excellent sound insulation at both low and high frequencies. (Sound reduction index: Rw (dB) 34 dB).

Environmentally friendly panels

Phoenix and Sonex panels are environmentally friendly and easy and accurate to use. They are produced from fully renewable and premium quality Birch hard wood on a production line utilizing innovative and advanced production technology at the Metsä Wood plywood mills in Finland.

Phoenix and Sonex panels are produced mainly from wood originating from Finland and thus certified according to PEFC, the prevailing certification scheme in the country. Certification is a tool to ensure sustainability of the supply chain as well as the forestry operations.

Metsä Group (mother company of Metsä Wood) is owned by 125,000 private forest owners (50% of the privately owned forest in Finland) and we can therefore guarantee a continuous wood supply to our mills. All the wood that we use originates from sustainably managed forests and we always know the origin of the wood we use. We ensure and promote a high level of nature management and safeguard biodiversity in our forestry operations.
