Why this product
This product combines sound absorption with performance in outdoor environments, making it an ideal solution for industrial and infrastructure projects that require a durable, lightweight material with proven long-term acoustic performance.
Technical description
The 50 mm Whisper UV-Eco panel is an advanced sound-absorbing element designed for industrial and infrastructure applications that require a combination of sound absorption and reduced sound transmission.
The panel is made of polyethylene foam with a closed-cell honeycomb structure, which allows sound waves to penetrate the material, creates resistance to airflow and converts sound energy into heat (damping).
This structure helps reduce sound reflections, improve reverberation time (RT) and create a balanced acoustic environment, particularly at mid-to-high frequencies.
In addition, thanks to its closed-cell structure, the panel is highly resistant to harsh outdoor conditions, including exposure to UV, humidity and water, while maintaining its mechanical stability and acoustic performance over time – a significant advantage over fibrous materials.
The product has been tested to international standards and has a high sound absorption coefficient (αw ≈ 0.90, Class A), along with performance data that also make it suitable for infrastructure applications such as railways and roads.
Applications
- Industry and factories
- Plant rooms
- Infrastructure and rail
- Airports
- Outdoor facilities

Installation
The panel can be installed using several methods, depending on the application, the type of surface and the environmental conditions:
Mechanical fixing (recommended for industrial and outdoor use):
Fixed with dedicated anchors/screws directly to the wall, ceiling or framing.
This method ensures high long-term stability, especially in outdoor environments or areas exposed to vibration and loads.
Installation on framing:
The panels are fixed to metal/timber frames as part of an acoustic system (walls, partitions, cladding).
Particularly suitable for industrial and infrastructure projects.
Adhesive bonding:
Can be bonded with a high-quality contact adhesive or a dedicated polyurethane adhesive.
Suitable for smooth, dry surfaces where there are no mechanical loads.
Key points:
- For outdoor use – mechanical fixing is always recommended
- Make sure the surface is clean, dry and stable before installation
- Can be cut and fitted to size on site
- For optimal performance, combine with proper acoustic design
