Specifically manufactured material for acoustic sound insulation in false walls. It is made of a fixed combination of two natural materials which both posses very good properties in terms of soundproofing. This material can be used in combination with other insulation materials to improve better overall qualities.
The corkboard material is a natural product (vegetal) originating from cork. The cells of the expanded cork contain 50% of air, are waterproof and are expandable. The Corkboard is not only a good thermal but also a phonic and vibratic insulator.
The natural Cocos material provides great acoustic damping and has a leveling effect.
