Description
Composition
3-layer composite panel consisting of two outer layers of marine plywood (on specific request with RINA approval) and a centre core of cork-rubber, 3 mm thick.
The cork-rubber has a specific gravity of 900/1020 kg/m³, but it is also available in a light version with a specific gravity of 650/900 kg/m³.
The panel can also be constructed with 3.6-mm and 6.5-mm "ultra heavy" rubber, with a specific gravity of 8 kg/m² and 14 kg/m², respectively.
Applications and Use
Projects that require a high level of mechanical performance and a high level of acoustic insulation performance.
