Soundac Cork and Cork Rubber

Product catalog summary

Description
Soundac® K224 and KR625 are flexible, lightweight cork and cork rubber sheets designed for optimal sound insulation with minimal weight. They are suitable for improving the insulation of panels made from materials such as steel, aluminum, wood, and plastic across all frequencies. These sheets are typically installed in close contact with the original panel.

Stock and Customization
The mats are available in standard sizes and are always in stock. Specifications can be customized to meet specific requirements, and offers can be provided without obligation.

Product Specifications
Soundac® K224 is available in 4 mm (1.0 kg/m²) and 6 mm (1.3 kg/m²) thicknesses. Soundac® KR625 is available in 4 mm (2.5 kg/m²) and 6 mm (3.8 kg/m²) thicknesses.

Application
These products effectively address coincidence dip resonance in stiff lightweight composites like plywood sheets and hollow core panels. They are commonly used in the production of lightweight floor and wall panels for yachts. Available thicknesses include 4, 6, 8, and 10 mm.

Installation
To prevent sound leakage, all joints between sheets and around pipes and air ducts should be thoroughly sealed. The mats should preferably be glued over the entire surface to the substrate.

Performance
Transmission loss for Soundac® K625 in a 12 mm sandwich panel is Rw = 30 dB, and for Soundac® K224, it is Rw = 27 dB.
