Pet-felt panels
PET felt panels from In-Zee offer the ideal balance between high-quality sound absorption and a durable, aesthetic design for any business space. As a specialist in acoustics we transform recycled materials into custom-made solutions that bring peace and atmosphere to your interiors.
Innovation from recycled bottles
At In-Zee, circularity is at the heart of our production process. Our PET felt panels consist of at least 60% of recycled plastic bottles, directly contributing to the reduction of plastic waste. At our own production facility, we process this material with solar-powered electric cutters, making our production energy-neutral. Thanks to the ‘No Screw, No Glue’ principle, the panels are also fully recyclable at the end of their life cycle.
The technical power of acoustics
The strength of PET felt lies in its open fibre structure, which effectively absorbs sound waves instead of bouncing them back. A standard 9 mm panel has an absorption value of 0.45, but through clever techniques such as an air cavity or additional acoustic wool, In-Zee can reach a value of up to 1.0. This absorbs sound almost completely, which is crucial for quietness in dynamic environments.
This optimisation translates directly into a better user experience in offices and public spaces. Good acoustics increase speech intelligibility and reduce cognitive load, preventing stress and promoting focus. With PET felt solutions from In-Zee you are therefore investing in an aesthetic interior that directly contributes to the health and productivity of the people in the room.
Customisation in colour and shape
No two spaces are the same, which is why In-Zee offers complete design freedom. With advanced CNC cutting techniques and an in-house design studio, we translate your vision into a functional result. Our PET felt panels distinguish themselves by:
- Wide colour choice: Available in 39 unique colours to match any house style.
- Flexible thicknesses: Standard 9 mm, or bonded to 18 mm and 27 mm for extra mass.
- High-quality finish: Options for V-cut, bevel-cut and thermal forming.
- Certified safety: Fire class B-s1-d0, suitable for project application.
Frequently asked questions
What is the acoustic value of PET felt?
PET felt has a base value of 0.45, meaning 45% of sound is absorbed. By placing the panels on a battens or combining them with acoustic wool, this value can be increased to 1.0 for maximum attenuation.
In what sizes are the panels available?
Our standard plates have a size of 2440 x 1220 mm. For specific designs, we can cut these plates into any shape or combine them to form larger wall and ceiling elements.
Is PET felt fireproof for office use?
Yes, our PET felt panels are extensively tested and certified according to European fire safety standards with fire class B-s1-d0. This makes them extremely suitable for project-based applications in public areas.
How does this product contribute to sustainability?
The panels are made of at least 60% recycled fibres from PET bottles. We also produce locally and energy-neutral, minimise cutting waste through re-use and design products that are fully recyclable.
