Why this product
The 40 kg/m³ Palziv board is designed for applications involving industrial loads and mechanical equipment, and enables effective acoustic decoupling between the machine and the structure.
The material offers a reliable solution for treating noise and vibration at the source, especially in demanding working environments.
Technical description
The Palziv PA40 board is a microcellular expanded polyolefin foam with a closed-cell structure, designed for industrial noise and vibration isolation applications.
The material’s elastic structure dampens vibration energy and reduces vibration transfer through structural elements, forming a decoupling layer (elastic isolation layer) between the noise source and the structure.
The material works by reducing the transfer of mechanical and acoustic energy, thereby minimising structure-borne noise caused by machinery and industrial equipment.
Thanks to its closed-cell structure, the board offers high resistance to moisture, water and chemicals, and retains its mechanical and acoustic properties over time, even under harsh operating conditions.
Applications
- Industrial machinery
- Compressors and chillers
- HVAC systems
- Plant rooms
- Technical facilities
- Floating bases (floating systems)
- Vibrating equipment
