Sustainable Polyester Acoustic Panels

Only 6% of all plastic is currently being recycled. Polyx™ acoustic polyester panels are an environmentally friendly acoustic solution made from recycled plastic bottles.

To bring a second life to plastic bottles, we make use of used plastic bottles to produce Polyx™ panels. By putting our focus on upcycling used plastic bottles instead of producing new materials, we save plastic from landfills and incineration.

Why Eco-Friendly Polyester Acoustic Panels Matter

Polyx™ acoustic panels are crafted using a specialized process that includes tumbling, needle-punching, and baking a blend of low and high melting-point polyester fibers. This creates a high-density fibrous structure, effectively absorbing sound and minimizing reverberation. The Polyx™ Board is available in four distinct thicknesses – 6mm, 9mm, 12mm, and 25mm – offering versatile options for varying acoustic requirements.

Recyled Materials

To bring a second life to plastic bottles, we make use of used plastic bottles to produce Polyx™ panels. The bottles are sent to the recycling centres in densely pressed bales from the junkyard. The sorting machine removes all the coloured caps and labels while cleaning and sorting them. The sorted bottles are then sent to the granulator.

Sustainable PET to Fibre

Large rotating blades shred the bottles into 1 cm flakes and remove any debris. What were once plastic bottles are now pure PET flakes. The PET flakes travel through an extruder, melting them and forming polyester fibres. As a result, hard plastic gets a soft wool-like texture. The fibres are then cut into thin sheets to prepare them for felting.

Felting and Panel Formation

The felting machine folds the fibre in layers and compresses it. Thousands of barb needles stab the material, turning it into felt. Following the same principle, three sheets of felt are merged together into a dense mat, ready for pressing. The pressing machine transforms the felt into a solid large panel while maintaining its wool-like texture.

Certifications and Standards

Backed by recognised certifications, our materials meet global standards for performance, safety, and sustainable design.

Certified Assurance

We engage laboratories accredited by the UKAS to carry out our independent testings. This ensures our reports are verified and internationally recognised, making sure that all performance data is accurate, consistent, and fully trusted across local and global projects.

Green Building

We actively support sustainable building goals under the LEED framework. Our materials are developed to contribute to LEED credits through acoustic performance, responsible sourcing, and low-emission properties, supporting environmentally responsible and sustainable design.

Global Standards

We align our processes with standards set by the International Organization for Standardization to ensure quality, environmental responsibility, and reliable acoustic testing. Standards such as ISO 11654 guide how we measure and report sound absorption performance consistently.

Performance Testing

We test our materials in accordance with standards developed by ASTM International to validate performance. Methods such as ASTM C423 allow us to provide dependable acoustic data, ensuring accurate specification and consistent comparison across different materials and applications.

Material Safety

We source materials that meet OEKO-TEX® requirements for product safety and chemical content. This helps ensure the textiles used in our systems are tested for harmful substances and assessed for safer indoor use, supporting healthier interior environments.

At Polyx™, we focus on enhancing building design and sustainability. Our acoustic panels, crafted from select PET materials, embody our commitment to quality. We prioritize building health and effective acoustics in our manufacturing, continuously seeking to innovate and redefine design standards. This approach ensures our panels are not just functional but also contribute to green building practices.
