Bend Without Breaking
The ultimate acoustic solution for curved surfaces. Made from recycled PET felt with precision V-cut grooves, these flexible panels adapt seamlessly to columns, curved walls, and any architectural form with a minimum radius of 500mm.
Re-Sound is a Stretch Group brand. We manufacture in our own plants in Beveren-Waas (Belgium) and Częstochowa (Poland).
Flex-Groove panels provide a versatile acoustic solution for curved surfaces, effortlessly adapting to any shape. Suitable for inner and outer radii, their flexible structure allows for seamless transitions along walls, columns, and other rounded architectural elements.
Each panel is incised with precision V-cuts, allowing it to bend without breaking. This smart cut creates the signature ribbed texture — a series of linear grooves that enable flexibility while giving the surface a sculptural relief.
Minimum Bending Radius
Engineered grooves for controlled flexibility
Smooth transitions on any curved surface
Efficient design reduces cutting waste
Our carefully curated color palette offers versatile options for any interior. From soft neutrals to bold statement colors, each shade is designed to complement modern architectural spaces while providing excellent acoustic performance.
Made from fire-retardant recycled PET felt, Flex-Groove panels provide effective sound absorption while maintaining visual continuity across curved surfaces. The grooved texture enhances acoustic performance.
Fire-Retardant PET Felt
Reduces echo and reverberation
Built-in fire safety properties
Made from recycled plastic bottles
Designed to span standard floor-to-ceiling heights, the panels simplify alignment and reduce installation time. The adaptable form makes them a practical solution for interiors requiring both sound absorption and design flexibility.
Ensure the curved surface is clean and ready for mounting
Use recommended adhesive on the panel back
Gently bend the panel to follow the curved surface
Press firmly to ensure full adhesion along the curve
Every Flex-Groove panel is crafted from 100 % recycled PET plastic bottles, giving new life to waste materials. Our circular approach ensures that these panels can be recycled again at the end of their lifecycle.

Yes. All rPET panels are OEKO-TEX® Standard 100 certified — verifying the absence of harmful substances. VOC emissions are tested to French A+ (the strictest indoor-air-quality grade).
Under EN 13501-1, rPET Flex Groove is classified B-s1,d0. The fire certificate is in the downloads block on this page; the other rPET models carry their own class on their pages.
Yes. rPET behaves like MDF on standard woodworking machinery: cut with a circular saw or CNC router, drill with twist bits, paint with water- or solvent-based finishes. No special protective equipment required.
12 designer colors are stocked for the rPET Groove and Flex Groove lines; the rPET Panel line is available in 16 colors. Custom colors can be produced for projects above 200 m².
Stock colors ship within 2–3 weeks; custom colors require 5–6 weeks. Large projects (>500 m²) are scheduled in production batches — contact us for a binding date.
